NoSQL Couch & Mongo Jobs

The application is being built on the MERN stack—MongoDB, Next, React, and Node.js—and every line you write will be pushed to GitHub by the end of each workday so progress is always transparent. I work in a live environment, so quick turn-around on questions, fixes, and new features is essential. Core feature set • Secure user authentication with robust session handling • Payment gateway integration (Stripe or similar) wired cleanly into the back-end API • Solid database connections in MongoDB with efficient querying and indexing • External API integration for third-party services • Real-time debugging and hot-fixes as issues surface Acceptance criteria • A GitHub repo showing daily commits and clear commit messages • React fro...

I’m putting together a machine-learning driven web app and need an experienced hand across the whole stack: Supabase for the database layer, FastAPI powering the backend, Vercel handling the build and edge deployment, with the domain and any auxiliary services running through Hostinger. The core goal is simple: ship a production-ready web application where the ML logic is exposed through FastAPI endpoints, persisted in Supabase, and served to users via a responsive front end that Vercel can build and deploy automatically on every push. I already have accounts on all four platforms and can grant access immediately. Here’s what success looks like for me: • Supabase: a well-structured Postgres schema, relevant RLS policies, and JWT-based authentication tied into the FastAP...

Connect CRM dashboard (Admin + User panels) to backend APIs. Set up Mapbox, WhatsApp API, AI assistant, push notifications, and cloud storage. Implement reporting system (weekly + monthly). Configure and deploy backend on a server (Render/Railway/AWS). Add all environment variables. Connect backend to frontend (Netlify) and complete final QA testing. Goal: A fully working backend ...

Phase 1 starts with a deep dive into our current stack. The most urgent pain point is Twilio: messages simply never reach some users or reach them far too late, and the pattern seems tied to certain carriers. I need you to trace the root cause, implement a reliable fix, and document what changed. While you are inside the codebase, upgrade Node.js to the latest stable LTS, profile the app for slow-loading pages, and squash the intermittent login failures that keep appearing in our logs. I’m looking for clear, reproducible steps that prove each issue is resolved and a short write-up that flags any other weaknesses you spot. Phase 2 shifts to strategy. Our content team struggles with Prismic slices; routine edits turn into dev tickets. I want an informed recommendation on whether we s...

I need a developer who already knows the BlueBubbles code-base to tailor the desktop client exclusively for macOS and connect it to my existing Firebase project. My immediate priorities are: • Cloning the current BlueBubbles Electron/Node repo and configuring it to build cleanly on the latest macOS release. • Replacing the default Firebase placeholders with my project keys so Cloud Messaging, Firestore syncing and presence tracking all work out of the box. • Producing a signed, notarized .dmg plus the updated source so I can recompile in the future with a single command. I will provide the Firebase credentials and a test Apple ID once we start; you provide concise setup notes and any scripts you add. The finished app must sign in, display chats, push new messages in ...

I have an active Node.js codebase that needs an experienced hand to move it forward. The immediate priorities are reviewing the existing modules, identifying bottlenecks, and delivering clean, well-tested updates that follow modern best practices. You should be comfortable navigating asynchronous patterns, integrating third-party APIs, and profiling performance issues in production-like environments. I’ll share full repository access, a brief architecture diagram, and a set of test cases once we connect. From there, I expect concise pull requests with clear commit messages, inline documentation, and a short summary of what was improved or fixed. If you are available to start soon and can point to prior work that demonstrates solid Node.js mastery, send over a quick note and we can d...

I’m building ReFocus, a digital-wellness web app for students, and I need an experienced Node.js / Express / MongoDB developer (full-stack is a plus) to finish and fix the backend + role-based flows. Current status Frontend: React + Vite, deployed on Vercel (working). Backend: Node.js, Express, Mongoose, JWT auth, MongoDB Atlas. Basic auth routes exist but are incomplete/buggy. User roles: admin, coach, user. What I need Review and clean up existing backend code and API structure. Fix and finalize authentication & authorization: Login / register Email / password rules (simpler rules) Proper role-based access so each role only sees their own dashboard and pages (admin dashboard, coach dashboard, normal user pages). Implement / complete main features: User profile &...

I’m building a subscription-based shipping and order-management platform for Australian merchants and I need help turning the concept into a production-ready web app. Core workflow • Tenants sign up, connect their Australia Post account and immediately start importing orders via CSV. • Labels are generated, orders are tracked in real time and fulfillment events are pushed back to the tenant’s dashboard. • Stripe handles metered billing so each tenant is charged automatically according to monthly label volume. Tech stack I’d like you to follow React on the frontend and a Node.js (Express or Nest) back end. Data isolation must be baked in from the start—each tenant should live in its own logical partition with role-based access for staff. ...

I have a production MERN application that has begun showing functionality bugs and noticeable slow-downs under load. I need a developer who can dive into the existing MongoDB, Next, React, and Node.js codebase, trace the root of those issues, and optimise both the server and client so response times return to normal. Alongside stabilising the app, I also want to move the product forward. A handful of new features are already scoped in Figma and Jira, and several external APIs must be connected so we can expand our data sources and prepare for future payment-related work. I will walk you through the backlog on our kick-off call and grant access to a private Git repository plus detailed Postman collections. Deliverables • Resolve all current functionality bugs (error logs supplied)....

My website currently reaches roughly 86 million registered users, yet daily engagement has stalled. I need a developer who can analyse the existing codebase, propose interaction-driving improvements, and implement them end-to-end without disrupting the live service. Think modern, friction-free features that keep visitors talking, reacting, and returning—whether that’s a dynamic commenting layer, real-time activity notifications, or other creative elements you know will work at scale. You’ll start by reviewing the frontend (React) and backend (Node + Mongo) to map what’s already in place, then suggest interaction modules that integrate cleanly with our tech stack. Once we agree on the plan, I’ll expect iterative releases on a staging server, load-testing to pr...

I’m spinning up a new backend and want a hands-on developer who can jump straight into building production-ready, secure APIs. The stack is Node.js with Express, PostgreSQL on the data layer, and Microsoft Graph for several integration points. You should already be comfortable handling OAuth flows and token management because authentication is wired through Azure AD. My priority is robustness: clean, well-documented endpoints, solid error handling, and security baked in from the start. If you have experience tightening Node.js applications against attack vectors, you’ll feel at home here. Please tell me about projects where you built or hardened APIs on a similar stack. I’m particularly interested in how you approached authentication with Microsoft Graph or secured Post...

I’m leading the build-out of a custom enterprise-grade business application and now need an experienced backend architect to validate existing architecture. The stack is not yet fixed; strong, production-level mastery of any modern backend environment—Node.js, Python, or Java—will be considered as long as you can justify how it serves scalability, resilience, and easy maintainability in an enterprise context. Expect to work with high-traffic data flows, role-based access control, and a modular service layout that can grow into multiple business domains over time. What I need from you: • A comprehensive architecture blueprint (micro-services vs. modular monolith, database sharding strategy, messaging, CI/CD pipeline choices). • Clear API specifications an...

I have a partially-built MERN application that needs to move from “prototype” to “polished product.” The immediate task is to integrate a Sign Up / Sign In flow that feels modern—think clean lines, generous white space, and subtle micro-interactions. Users should be able to authenticate through social media, opt into multi-factor verification, and recover forgotten passwords without friction. Once the authentication layer is in place, I want the same contemporary aesthetic carried through an all-new dashboard. I’m picturing a clear information hierarchy, responsive layout, and intuitive navigation so future features can slot in easily. The final milestone is a built-in blog where I’ll publish personal stories. It needs standard CRUD, rich-text ed...

I run a live, cross-platform stock-advisory app that also delivers bite-sized financial lessons to users on both Android and iOS. The front end is entirely Flutter, the API layer is Node.js, and the data sits in MongoDB. Everything is already in production; what I need now is an experienced all-rounder who can keep that stack healthy, fast, and moving forward. Here’s what the role looks like day-to-day: • Diagnose and squash production bugs before they ripple out to users. • Build and ship new user-facing features in Flutter as we expand the lesson library and advisory tools. • Keep an eye on performance—from frame rate on older devices to query speed in MongoDB—and optimise whenever we slip below target. • Maintain and extend the Node.js API, ...

1. pakistan developer 2. india developer only contact please. I’m building a production-grade backend in NestJS and need a seasoned Node.js engineer to push it across the finish line. The stack is modern JavaScript/TypeScript on top of NestJS, backed by MongoDB, and version-controlled on GitHub. Your main focus will be to design and refine RESTful endpoints, implement solid error-handling patterns, and fine-tune performance—especially around MongoDB query optimisation and overall request latency. A deep grasp of asynchronous programming, callbacks, and event-driven architecture is essential because some critical flows rely on websockets and background jobs. Git skills matter; you’ll be working through pull requests in a shared GitHub repository and following a clean ...

I need a solid Python build that blends a clean, browser-based interface with powerful data-scraping logic. The goal is a self-contained web application that can pull information from three distinct sources—websites, APIs, and internal databases—then present or export that data on demand. Here’s how I picture the flow: from the front end I choose the target (URL list, API endpoint, or DB table), set any parameters or credentials, and kick off the scrape. Behind the scenes your Python scripts handle the session management, parsing, rate-limiting, pagination, and error recovery. Results land in a single unified store—SQLite or Postgres is fine—and the UI lets me filter, download CSV/JSON, or trigger another run. Deliverables • Responsive web UI (Django,...

An API built in Node .js is required to pull detailed Instagram profile and audience metrics so they can be consumed by an existing platform. The highest-priority data points are followers, following, engagement rate, audience country, e-mail addresses, and city/state, followed by age, gender, fake-versus-real follower ratio, profile picture and post metadata. Engagement rate must follow the “likes + comments over a period of time” formula; please make the period configurable so I can test different windows later. The service should expose clear JSON endpoints, return clean, well-typed responses, and include concise setup instructions for deployment on a standard Node environment. Before final hand-off I need a simple document that flags any fields Instagram does not make...

I already have a working prototype hosted on Replit: The core screens and features on that link must stay exactly as they are; what I need now is the infrastructure and polish that turns it into a production-grade tool for my resort. Access & authentication • Staff will log in from both smartphones and laptop . • Login should rely on phone number + password for everyone, with one admin account holding full privileges. Cloud architecture The app has to run on a scalable cloud stack (AWS, Firebase, Supabase, or any comparable service) so that data is instantly synced across all devices, even on spotty resort Wi-Fi. I also need an admin dashboard in the cloud where I can oversee everything in real time. Data export From within the dashboard I must be able to export...

We are looking for a Senior Full-Stack Engineer to architect and build our MVP using 14 (App Router), React 18, TypeScript, MUI 5, Prisma, and PostgreSQL. The role requires end-to-end ownership: implementing multi-tenant Clerk authentication, designing REST APIs with Route Handlers + Zod, building admin dashboards, handling file uploads, blob storage, PDF/Excel export, adding i18n (next-i18next), and setting up background jobs with Upstash/Redis. Applicants must have strong skills in DevOps (Vercel, env management, DB migrations), security, GDPR-compliant development, and enterprise UI patterns. This is a solo senior role requiring someone who can independently deliver production-ready architecture and features. Check the attached PDF for detailed skill requirements. thanks, chris

I’m ready to launch a full-scale online marketplace dedicated to physical goods and need a developer who can take the project from blank server to live storefront. Shoppers must be able to browse vendor pages, add items to a unified cart, and check out seamlessly with credit/debit cards, PayPal, or a direct bank transfer. Product pages have to feel trustworthy and engaging, so every listing needs space for several high-quality images, a star-based rating, and text reviews that appear only after verified purchases. A clean seller dashboard for inventory, order processing, and payout tracking is essential, while I need an admin panel that lets me approve vendors, resolve disputes, and feature select products. The build should be responsive for mobile and desktop, optimised for fast...

Voy a poner en marcha un ERP contable hecho a la medida y necesito que te encargues del desarrollo completo: Java en el backend, Angular en el frontend y PostgreSQL como base de datos. Todo el código debe quedar estructurado para crecer por micro-servicios más adelante, pero en esta fase se entrega como un solo proyecto bien desacoplado por capas. Cada uno de los módulos deberá ser totalmente personalizado —no partimos de plantillas ni de paquetes prefabricados— y compartir el mismo esquema de seguridad: registro e inicio de sesión con correo electrónico y contraseña, con roles gestionados desde la propia aplicación. Módulos que entran en esta primera iteración​ • Compras • Inventario • Produ...
