I need an Android-only utility that quietly watches whichever app screen I choose and alerts me the moment a word, phrase, symbol, or emoji I have entered appears anywhere on that screen. The content could be part of a photo, a running video, a PDF, chat text—anything visible to the eye. As soon as the target string is recognised the app must raise a standard Android notification with sound and vibration. Key working rules • 100 % offline: no internet access, no background data, no cloud calls. • On-device OCR: embed the engine (Tesseract, ML Kit, or similar) so recognition happens locally. • App picker: I can toggle monitoring on or off for any installed app. • Keyword manager: a simple manual entry field where I add or remove words, special characters, or...

“When Whild” is a fresh social–networking concept that I want built first for Android. I already have the core idea and brand direction; what I need now is a developer who can turn that vision into a clean, dependable APK that is ready for Play Store submission. The scope covers everything from setting up the project structure, implementing the standard social features (user sign-up/login, profile creation, posting/sharing, simple notifications), through to basic analytics and crash reporting so I can monitor early traction. Material Design guidelines should steer the UI/UX, and Kotlin is preferred for maintainability, though I am open to Java if you have a compelling reason. Key deliverables: • Fully functional Android app (APK + source) • Clear build/ru...

I need an Android application that brings two things together under one roof: property-focused features for buyers, sellers and renters, and on-demand “mistri” (skilled worker) services for repairs, renovations and maintenance. The idea is to let users browse listings, schedule site visits, and, with the same account, hire verified carpenters, electricians, plumbers or other tradespeople. Here is what I expect as the finished deliverable: • A clean, modern UI that runs smoothly on current Android versions. • Two interconnected modules—one for real-estate listings with search, filter and basic enquiry functions, and one for mistri bookings with service categories, pricing and simple time-slot selection. • Secure user registration/login tied to phone nu...

I need a straightforward Android app that lets field staff collect asset-related inspection data, attach photos on the spot, and then produce a clean, branded PDF report automatically once they hit “submit.” Core workflow • User opens the app, selects or creates an asset, fills in the inspection form, snaps the required photos, and saves. • When the form is completed, the app compiles all inputs (text, photo thumbnails, time/date, inspector name) into a well-formatted PDF and prompts the user to share or store it locally/on the device. Key requirements • Native Android build (Java or Kotlin). • Reliable in-app photo capture with compression so PDFs stay lightweight. • Offline first: the inspector must be able to work without a signal and...

I need fresh eyes on an AI-powered chatbot that lives inside an Android mobile app. Your main task is to talk with the bot as a normal user would, then tell me exactly where it shines, where it hesitates, and where it flat-out fails. Here’s how the work will flow: • Install the current APK I provide and register with a throw-away account. • Run through a set of typical user scenarios I’ll outline (ordering, support queries, small-talk, and a few edge cases you invent on the fly). • Capture screen recordings or annotated screenshots whenever you spot odd replies, broken UI elements, or latency spikes. • Summarise findings in a concise report, grouping issues by severity and adding reproduction steps so my devs can trace them quickly. If you notice...

I’m building a production-grade web application and need a seasoned full-stack Java developer to drive the effort from architecture through deployment. The back-end will be written in modern Java with Spring Boot at its core, using Hibernate for ORM and a microservices design to keep the codebase modular and scalable. You’ll own everything server-side: designing RESTful endpoints, modelling the database, securing the APIs, writing unit and integration tests, and containerising the services for smooth deployment. If you prefer bringing your own front-end stack, that’s fine—Angular experience is certainly welcome but not essential, as long as the UI integrates cleanly with the services you expose. When you respond, focus on the depth of your experience deliverin...

I’m expanding InsureNet with an AI-powered module focused exclusively on assessing cyber risks for our business customers. The goal is to combine three proven methods—vulnerability scanning, threat-intelligence analysis, and security audits—into a single, automated workflow that produces a clear risk score and supporting evidence that underwriters can trust. What I need from you • Build or integrate reliable vulnerability scanners (OWASP ZAP, Nessus, or a comparable open-source tool) that can be triggered via API and return normalized findings. • Pull real-time threat-intelligence feeds (STIX/TAXII, CVE databases, commercial feeds if you have access) and correlate them with the scanner output. • Design an ingest mechanism for security-audit data so t...

I’m assembling a worldwide team to design and deploy next-generation intelligent systems. My own focus is Artificial Intelligence, and every project on our roadmap—from rapid prototypes to production-grade platforms—relies on solid expertise in the field. The core technical stack revolves around: • Machine Learning • Natural Language Processing (NLP) • Computer Vision If you work comfortably across those areas and can demonstrate real-world results, we should talk. Contributions may range from model architecture and data-pipeline design to API integration and performance tuning; exact scopes will be matched to each contributor’s strengths. When you send your proposal, highlight the experience that best proves you can deliver impact quickly (p...

I’m steering a compact product sprint and need one versatile freelancer who can move fluidly between code, pixels, and data. Day to day you’ll script backend logic in Python, wire up interactive elements in JavaScript, and maintain a small Java micro-service. When we pivot to visuals, you’ll open Adobe Photoshop, Sketch, or Figma to polish UI mock-ups and marketing assets. Rounding things out, you’ll dive into raw numbers with the data-analysis platform of your choice, turning them into clear, actionable visuals. Deliverables • Clean, well-documented modules in Python, JavaScript, and Java • Finalised design files exported from Photoshop, Sketch, and Figma • Concise analytic report with reproducible steps and charts Acceptance criteria: ever...

Must explain workflow properly. Long-term work possible.

I want Clauld AI Mythos to evolve into a smart, text-driven analytics engine. Its sole focus is data analysis, extracting insights, patterns, and trends from large volumes of text—think natural-language processing, topic modelling, entity recognition, and sentiment breakdowns that decision-makers can act on. Here’s how I picture the workflow: 1. Ingest raw text through a clean, modular pipeline (API or batch upload is fine). 2. Process the corpus with Python and state-of-the-art NLP libraries—spaCy, HuggingFace Transformers, or similar—so the architecture remains future-proof. 3. Generate clear, exportable outputs: interactive dashboards (Streamlit or Dash are welcome), concise PDF/CSV summaries, and machine-readable JSON for downstream use. Acceptance crit...

I need a small-scale platform built on the official WhatsApp Cloud API that automatically sends order-update messages to my customers. The flow should trigger from my existing system (a simple webhook is fine) and push status notifications—order confirmed, shipped, out for delivery, and delivered—without manual intervention. Beyond the push messages, I also want an AI-powered conversational layer so customers who reply can get immediate, relevant answers. When the AI reaches its limits, the chat must hand over cleanly to a live agent through an agent console or any lightweight web dashboard you provide. The agent should see the full history and be able to take over in real time, then return control to the bot once done. Key deliverables: • WhatsApp Cloud API integration ...

I need an AI-driven solution that will remove the manual grind from our image-heavy data entry and management flow. The end product should pull raw image files from a designated source, read the embedded or visual information, classify or tag each file correctly, and populate our existing database automatically. Accuracy is the top priority; any mislabeled or unprocessed images must be flagged for human review rather than slipping through. Here is what success looks like for me: • A repeatable training pipeline (Python preferred,TensorFlow or PyTorch are both fine) capable of handling new images as the dataset grows. • An inference service that runs on-prem or in the cloud—AWS S3 / Lambda is ideal, but I’m open to workable alternatives—that accepts a batch ...

I want to build a brand-new web application from the ground up and need someone who can comfortably handle every layer of the stack. Because this is a fresh build rather than an enhancement or a quick bug-fix, I’m looking for a developer who enjoys shaping architecture, choosing the right technologies, and iterating thoughtfully. There’s no hard deadline pressing us, so we can focus on clean, maintainable code, solid test coverage, and a deployment pipeline that scales. Here’s what I have in mind: you’ll design the database schema, implement the back-end API, craft a responsive front-end, and set up CI/CD so the project moves smoothly from development to production. I’m open to your recommendations on frameworks, languages, and hosting—what matters most...

I’m setting up a series of REST services built on Java 17 with Spring Boot and need an experienced backend developer to take ownership of both new features and ongoing maintenance. The core of the work is writing clean, test-covered code that exposes reliable, versioned endpoints, backed by a MySQL data store accessed through JDBC and, where appropriate, JPA/Hibernate. All modules sit in a microservice architecture and are managed through Git, so solid branching and pull-request discipline is essential. While the focus is the backend, it will help if you can speak the same language as our UI team; they primarily work in React and Angular with plenty of vanilla JavaScript, HTML, CSS, Bootstrap—and the occasional PHP snippet for legacy views—so being able to align contract...

My Kotlin-based Android app emulates a generic Xbox-style gamepad. It advertises itself as a Bluetooth LE HID GamePad and Windows happily pairs with it, requests InputReports, and even receives my packets—yet the data isn't being received by test programs. The frames appear to leave the phone intact, so something in the report composition, descriptor, or timing is clearly off. It is tantalizingly close, but I can't seem to "bring it over the finish line" and I need a fresh set of eyes to locate and correct the fault. You’ll be working with clean, well-commented Kotlin code that is already broken into clear layers (BLE transport, HID descriptor construction, game-logic encoder, MVVM). The task is to trace why the InputReport that “looks” correct ...

My Flutter app is feature-complete and already builds successfully, but before I release it to users I want a fresh pair of expert eyes on it. I need you to run a full quality sweep, identify any bugs—no matter how small—then patch them and ship clean release builds for both iOS and Android. The scope in a nutshell: • Audit the existing Dart/Flutter codebase, dependencies, and build settings. • Reproduce and document every issue you find, from crashes to subtle layout glitches. • Fix each problem in the main branch, keeping the codebase null-safe and compatible with the latest stable Flutter SDK. • Configure signing, provisioning profiles, and release flavors; generate production-ready .ipa and .aab files. • Prepare all App Store Connect and ...

Hi, I’m Yash in Mangalore and I’m ready to move quickly on a brand-new Android application. I’ve chosen mobile app development as the scope and Android as the platform, and I’d like to see a first release live within the next month. The core idea and feature set are drafted, but I value your input on the best architectural approach, UI/UX polish, and any performance or security considerations specific to Android.

I need an experienced Android-focused app developer to build a Transport Bilty application that lets trucking or logistics staff create, store and share digital bilty (consignment) documents directly from an Android phone or tablet. Core idea – A clean interface where a dispatcher can enter shipment details, vehicle and driver data, generate a unique bilty number and instantly save it as a record. – Saved records should be searchable, editable and exportable as PDF or image for WhatsApp/email sharing. – Data must live locally first, with the option to sync to a simple cloud back-end (Firebase or your recommended alternative) when a connection is available, so the app still works offline on the road. Key screens I expect 1. Login / user PIN (basic security) 2. ...

I’m planning a new website and want it built end-to-end with the tools I already trust—Java, Spring Boot on the server, ReactJS on the client, and either MySQL or MongoDB for persistence. The single non-negotiable feature is solid user authentication: registration, login, encrypted passwords, session/ token handling, and a clean path for future additions such as social-login or multi-factor. You will design the architecture, craft the REST APIs, wire the React front-end, and set up a responsive UI with clean HTML / CSS / JavaScript. Code should live in a GitHub repo with clear README, build scripts (Maven or Gradle), and environment files so I can stand it up locally or in the cloud without surprises. Please tell me about projects where you’ve delivered similar Java-Spr...

I want to launch an on-demand security-guard platform made up of three tightly integrated parts: a customer-facing Android app, a guard-facing Android app, and a web-based admin panel. Customer app Users must be able to search for available guards, schedule or book instantly, watch a real-time map as the guard travels to the job, and leave ratings or reviews once the work is done. Smooth in-app payments and push notifications for booking status changes should sit behind these core flows. Guard app Guards receive job notifications, choose to accept or decline, see turn-by-turn GPS navigation, and manage an up-to-date work calendar from their phone. Their location feeds the customer’s live-tracking map, so the background GPS service needs to be battery-efficient and reliable...

I need a WhatsApp-based AI system that takes over three daily pain-points at my school: distributing timely notifications, answering routine questions, and helping with light administrative chores. Students, parents, and staff will all interact with it, so the bot must recognise who is writing and then act accordingly—sending each person only the information that fits their role. For notifications, I want individual messages, not bulk blasts. A parent should receive fee reminders and event updates, a student gets timetable changes, while staff receive internal alerts. The same identity awareness should guide the FAQ module; the answer to “What time does school start?” may be different for teachers on duty than for learners. Key expectations • Integration with the o...

My Android app is fully built, tested and already aligned with Google Play guidelines. What I now need is a smooth, end-to-end submission to the Play Store. You’ll log into the Play Console, set up a compelling store listing and push the first production release live. I answered “Yes” to needing help with the listing, so please handle every public-facing detail—app name, long and short descriptions, graphics, screenshots, content rating and policy declarations. I can supply raw assets (AAB/APK, icon, artwork) and any text you need; you refine, format and upload them so they pass review the first time. Deliverables • Complete Play Store listing created and populated • App bundle uploaded with correct signing and versioning • All compliance form...

I need a small utility that sits on my Android phone and repeatedly performs a simple swipe gesture in the game I’m playing. The motion never changes, so a loop that keeps firing until I manually stop it is enough— no timers, no condition checks. You’re free to implement it as an APK with Accessibility Service permissions, an ADB script, or any other lightweight approach that keeps the device un-rooted and lag-free. All I really care about is: • I enter or edit the start- and end-coordinates (or drag to record them), • I press Start and the swipe repeats smoothly, • I press Stop and it halts instantly. Hand me the finished build or script with a brief note on setup and I’ll test it right away.

I need a developer who can replicate Meta’s system-level “floating overlay” on HorizonOS by creating an independent app that shows a WebView on top of any screen. This WebView will act as a HUD: it must load any URL I specify at runtime and display it without back, forward, or refresh controls. What makes the job tricky is that the original overlay relies on Meta’s private APIs. I already have the device rooted and running USERDEBUG, so full adb, shell, and file-system access are available. Your job is to: • Analyse the stock overlay APK (it is unencrypted and easy to decompile) to discover the required libraries, services, and signature checks. • Re-implement the floating interface using those same libraries so the new APK is accepted by the system....

I’m building a web-based Java application that performs intensive data processing while talking seamlessly to our database layer, several third-party APIs, and existing internal enterprise systems. The goal is a single, cohesive platform that ingests raw data from multiple sources, transforms it, and presents the results through a clean browser interface. Core expectations • A robust Java processing engine capable of scheduling, prioritising, and tracking data jobs. • A responsive web UI (desktop and mobile friendly) that lets end-users launch tasks, monitor progress, and download results. • Connectors for relational databases, REST/SOAP APIs, and our on-prem enterprise services, with clear configuration files so new endpoints can be added without code changes. ...

I am building a full-featured Student Management System in Java and I want the finished application to be clean, well-structured, and ready for hand-over to another developer or a teaching environment. Scope The core is a desktop Java application (Swing or JavaFX is fine) that lets me create, read, update, and delete student records while also managing courses, grades, and attendance. All data should persist to a MySQL database, but I am open to PostgreSQL or any other relational engine if that makes development smoother. Code Quality & Structure • Modern, layered architecture (DAO / service / UI) so future modules—such as Inventory, Library, or POS—could plug in without rewrites. • Thorough in-line comments and concise Javadoc on every public class or met...

I’m building a responsive web application from the ground up and need a developer who can move comfortably across React + TypeScript on the front end and Java + Spring Boot on the back end. The core of the project is rock-solid user authentication and authorization: every screen and API call must respect three distinct roles—Admin, Seller, and Buyer—so granular permissions, session handling, and token refresh logic will be central to your work. What you’ll be working with • Front end: React 18, TypeScript, modern CSS and a component-driven approach that renders well on desktop and mobile. • Back end: Spring Boot, building REST endpoints that handle the auth flow, business logic, and data services. • Database: MySQL, with clean schema design and...

I need to move a collection of Java-based operational reports away from iText and over to Apache PDFBox (or an equivalent open-source library) while keeping the existing Vibe coding style intact. The finished reports must still ship as PDFs and match the current layout, calculations, and branding. We should use any one of the leading Vibe coding tools such as Cursor, Claude code. Key features that have to work after the move: • Dynamic table of contents generated at run-time • Data filtering options passed in as parameters and reflected in the output No charting components are necessary. You will receive the current iText source, sample data, and a short checklist of unit tests. Please return clean, well-documented code free of all iText dependencies, build files, and a...

You’ll be taking charge of the server-side work for my application, and the core focus is clear: build a set of robust, well-documented RESTful APIs in Java. All persistence logic, request/response handling, and authentication layers will live in this codebase, so clean architecture and disciplined error handling matter a lot. Here’s what I expect to come out of this collaboration: • A modular Java codebase (Spring Boot or similar is fine) that exposes the required REST endpoints. • Well-structured data models mapped to the underlying database of your choice, with migrations/versioning in place. • Postman (or equivalent) collection and Swagger/OpenAPI documentation that let any front-end or third-party consumer hit the routes without guessing. • Unit...
