NoSQL Couch y Mongo Jobs

I'm building a new business-services platform and need end-to-end development help: polished React screens on the front, a solid Node.js API at the back, and a well-structured MySQL data layer tying everything together. The job spans UI/UX design through deployment. You’ll take wireframes and shape them into a modern, responsive interface, weave in secure user flows (contact forms, service pages, an admin dashboard), and keep performance, accessibility, and basic SEO in mind throughout. Clean, well-commented code, sensible component architecture, and Git-based version control are non-negotiable. For the backend, the brief is a RESTful (or GraphQL if you prefer) Node.js service written in expressive, testable JavaScript/TypeScript. Expect authentication, role-based permission...

I have a nearly-finished expense-manager app built with Flutter on the front end and a Node.js + MongoDB on the backend. My next step is to take it live. I already own and can access a Google Play Developer account, but I’m not completely sure the project is production-ready, so I’d like a specialist to handle the last mile. Here’s what I need: • Set up a production MongoDB database (collections and indexes match the current dev schema, any seed data that’s required, secure credentials, and environment variables). • Make sure the Node.js API is deployment-ready—dependencies up to date, build scripts finalised, something like Heroku, Render, AWS or GCP for hosting (open to your recommendation), and that it successfully connects to the new database...

I have a small web application built with the PERN stack that has a reproducible bug affecting data flow between the API and the frontend. The issue occurs when fetching and displaying records from PostgreSQL. The API responds, but the UI does not behave as expected in certain cases. This is a debugging task only — no new features, no redesign, and no large refactors. Scope of Work: - Investigate the API ↔ frontend interaction - Identify the root cause (query, API logic, or React state handling) - Apply a minimal, correct fix - Verify the issue is fully resolved Good Fit If You: - Have real experience with PERN or MERN-style stacks - Are comfortable debugging backend queries and frontend state Prefer short, focused tasks

I’m looking to get my full MercurJS commerce stack up and running on DigitalOcean’s App Platform. The project is made up of three containerised parts: • an API backend built on Medusa (Node.js) • a public-facing storefront • a React-based vendor panel Everything is already in a Git repository; what I need now is a clean deployment workflow on DigitalOcean that covers: 1. Container build & deploy for each service on the App Platform (not a droplet). 2. Environment variable setup and secret handling. 3. Automatic HTTPS and custom-domain routing for the storefront and vendor panel. 4. Connection of the Medusa API to an existing Postgres database. 5. Simple CI/CD so each push to main triggers a fresh build. If you’ve shipped Node.js...

I need a system that seamlessly ties together three core capabilities: • Secure user authentication • Reliable data-processing workflows • Clear, actionable reporting and analytics dashboards I’m flexible on the underlying platform—whether the solution is architected as a web application, mobile app, or standalone software—so feel free to recommend the stack you’re most comfortable with (React, Flutter, Django, Node, Laravel, .NET, etc.). Key expectations • Authentication must support modern best practices (hashed passwords, token-based sessions, optional social login). • Data pipelines should accept raw inputs, validate and transform them, then store results in a relational or NoSQL database you select. • Reports need bo...

I need an experienced Node.js engineer who can spin up a minimal yet production-ready backend for a mobile-app MVP within the next two hours. The stack is set: Node.js (Express or NestJS), PostgreSQL, Docker, and plain REST. Core tasks • Scaffold the project, containerise it with Docker, and deploy it to my cloud instance (I’ll supply SSH or registry access). • Create clean REST endpoints to create and fetch a single resource type so I can validate the mobile client flows. • Model the data in PostgreSQL; feel free to apply standard best practices as I have no special schema constraints right now. • Wire in an authentication layer that is already compatible with JWT; the mobile side will handle token issuance later, so the server just needs middleware ho...

I’m building a production-ready, user-facing web application and need a developer who can own the stack end-to-end. The front-end is React.js, the back-end runs on Node.js with Express, and all data is persisted in MySQL. You’ll shape new features with our UI/UX designer and product manager, translate wireframes into responsive components, develop clean server-side logic, and keep performance tight on both tiers. Well-structured, scalable code, thorough code reviews, and automated tests are part of our everyday workflow, so I’m looking for someone who shares that mindset. Along the way you’ll design and optimize the database schema, integrate third-party APIs, and continuously suggest technology or architectural improvements that future-proof the platform. Deli...

An existing web platform built with FastAPI for the API layer, for the interface, and PostgreSQL as its data store is roughly 80 % complete. Core authentication, routing, and database models are in place, yet several pieces still need tightening before a production launch. The immediate objective is to review the current repository, identify gaps, and implement the final set of fixes and enhancements. Outstanding work may include refining API response handling, extending a handful of endpoints, wiring the remaining React pages, polishing UI states, and cleaning up a few database queries that currently hamper performance. During our kick-off call we will agree on the exact priorities and sprint order, but code quality, test coverage, and deployment readiness are non-negotiable throughout....

I need hands-on, day-to-day help from a seasoned DevOps Engineer to keep our AWS environment running smoothly while we roll out new features. The immediate focus is on three pillars: building a reliable CI/CD pipeline, codifying our infrastructure, and tightening monitoring and logging so issues surface before our users ever notice.

Hi I will share the details with the shortlisted candidates. Thanks

My MERN stack application is ready for production and I need it running smoothly on an AlmaLinux server. You’ll start with a clean box that currently has only SSH access; no Node.js, MongoDB, or build tools are installed yet. I do want help setting up that entire environment, so plan on installing the required versions of Node, npm/yarn, MongoDB and any supporting packages. Apache is the preferred web server. Please configure it as a reverse proxy so the React front-end and Express API are both reachable under the same domain, served over HTTPS with a free Let’s Encrypt certificate. If you like using PM2 or a similar process manager to keep the Node processes alive, that’s fine—just document what you do. Deliverables: • Deployed, publicly accessible MERN ap...
