    I need an Android chat application built to MVP level within 2–4 weeks. Core scope is straightforward: • User login supporting Email and password, Google login, and Facebook login • Unlimited public chat rooms • One-to-one private messaging • Clean, basic UI that follows Material guidelines You’re free to use Firebase or a Node.js backend—whichever lets us move quickly while keeping the codebase easy to extend later. The first deliverable is a working APK and well-structured source code that I can open in Android Studio, followed by a concise setup document covering environment, database rules, and any API keys. If we hit the mark on stability, code clarity, and chat performance, I have a roadmap of additional features and platform roll-outs...

    I’m looking for an experienced Android developer to step in and refine an existing native app. The core build is stable, but it still lacks a reliable, well-structured push-notification system. Your task is to review the current Kotlin/Java codebase, integrate (or repair) FCM-powered notifications, and be sure they respect the app’s current UX flows—no rogue alerts, no missed messages. Once the notifications are live you’ll help me run a quick round of QA on a small device matrix, package a signed release APK, and supply the updated source in Git so I can keep the repository current. Clean commits, clear comments, and a short README on any new dependencies will be part of the hand-off. If you’ve shipped native Android apps before and can demonstrate tigh...

    I have an existing Java Spring web application that has been running for a few years and now needs a full refresh. The immediate priorities are: • Migrating everything to a brand-new server and hosting environment • Updating all Spring-related code and third-party dependencies to their latest stable releases • Implementing a handful of new features that have been on my backlog The current stack is Spring (Boot & MVC), Maven, MySQL and a small front-end in Thymeleaf with a sprinkle of jQuery. The code sits in Git and deploys on a Linux VM, but I’m open to Docker or any modern CI/CD improvements you can suggest during the move.

    Stealth is absolutely the top priority: once the project is finished the jar must register in-game exactly as the Fabric mod “yetanotherconfig.” Nothing in its mod-id, metadata, or display name can betray the real purpose.

Required behaviour • When I pop a totem the mod waits for a small, ever-changing delay (e.g., 0.123 s, then 0.214 s on the next pop, etc.), opens my inventory, and as soon as my cursor merely hovers a totem the item is moved to the off-hand instantly. • The routine must repeat until no totems remain. • The whole system toggles with the ‘ (apostrophe) key.

    My Android app is already built and functionally complete, but it still needs a final round of refinement before I can release it. The focus is on two areas: tightening up the user interface so everything looks consistent and professional, and squashing the remaining bugs that occasionally surface during normal use. No major performance overhauls are required at this stage—just solid, reliable cleanup work. Alongside that polish, I also need a straightforward web-based admin portal. The portal’s primary purpose will be to let me view and manage core data from the app (think user records, content updates, simple analytics, and basic configuration toggles). A clean dashboard with standard authentication is enough; nothing overly complex for now, but it should be built with an ey...

    1- Update application calls should have zero delay so that calls go at full speed. 2- Latency is very important — locally it's 250-300ms, so after deploying on AWS it should be minimum 200ms. So delay = 0 and latency should be low so calls hit fast. 3- We need to pick jobs, and for that we need to eliminate 429, 403, and 504 errors. Why does 429 come? Because we reuse the same token too fast. 403 comes when multiple calls hit from the same IP or combination calls hit together. 504 doesn't come that often, so for that we can keep a retry mechanism. 4- To eliminate 429, we need to use multiple tokens, because a job will only be picked when calls go without even a single 429, with latency 200-250ms and delay 0. 5- For that, we need to do the following: Enter one combination of...

    I have a working utility-focused app running on and I now need it packaged as a native Android application. The goal is a seamless, faithful reproduction of the existing web experience, compiled in Android Studio and ready for upload to Google Play. Scope • Mirror every current screen, workflow, and interaction exactly as it behaves online. • Keep the codebase clean and modular so future feature additions (such as push notifications or data sync) can drop in without a full rewrite. • No multi-language layer is required; all strings may remain in English for now. Deliverables 1. Complete Android Studio project with source code. 2. Release-ready APK/AAB, properly signed. 3. Short read-me explaining build steps, key classes, and where future feature hooks can b...

    I need a lightweight, self-hosted URL shortener that runs on my VPS under my own domain and uses Java for the backend with a MySQL database. The core feature is the ability to create fully branded links such as (custom slugs, no third-party dependency) and redirect them instantly. The admin dashboard can stay basic and purely functional; as long as I can add, edit, disable, and delete links quickly, that’s perfect. Analytics must be baked in—total and unique clicks, referrer data, visitor location, and timestamps—all viewable in the same interface. Every redirect has to be fast, reliable, and HTTPS-secure; I already have an SSL certificate on the server, so the application just needs to respect it. Full code ownership is essential. Please include: • A clean Java ...

    I have a fully finished Android game that is ready to ship to Google Play. What I need from you is straightforward: use your publisher account or guide me through mine to get the build live, set up the listing (screenshots, icon, content rating, privacy policy link, etc.), handle initial release approval, and then provide ongoing maintenance—version updates, compliance checks, crash-related fixes, and timely replies to any store alerts. The build itself is final, so no code changes or feature tweaks are expected right now, and I’m not looking for extended ASO work; the focus is on smooth publishing and reliable upkeep once it is in the store. If you already manage several games on Google Play, know your way around Play Console policies, and can commit to quick turnarounds fo...

    I need an Android application that lets customers schedule at-home servicing for both bikes and scooties in just a few taps. The single must-have feature for this first release is a smooth, location-aware booking flow: the user opens the app, grants GPS permission, selects bike or scooty, picks a service slot and confirms. No real-time tracking or payment gateway is required at this stage—capturing the booking details and pushing them to my team is enough. A modern Material-style interface, compatibility with recent Android versions and fast load times are important to me. Feel free to use Kotlin with Jetpack components or another current stack that keeps maintenance simple. A lightweight back-end (Firebase, Supabase, or a small REST API) is fine as long as bookings reach an admin d...

    I have an existing GitHub repository that works well in its current form, and now I need it packaged as a fully functional mobile application for Android. The core logic and assets are already available in the repo; what I’m missing is the Android-specific layer—activities/fragments, UI, permissions, Gradle setup, and anything else needed to publish on the Play Store. Your task is simple in scope but requires solid Android expertise: • Clone the repo, study the codebase, and wire it into a standard Android project structure (Kotlin or Java—use whichever fits the code best). • Build out the necessary UI so every feature that runs in the GitHub project works seamlessly on an Android device. • Handle all mobile-specific concerns such as runtime permissio...
