MongoDB Jobs

I need a full-featured application built on the MERN stack for the web and a native Android counterpart created in Android Studio. Both must share a single MongoDB database and a secure RESTful API layer written with Node.js and Express.js. The web front end should be React.js, delivered as a standard responsive website while also shipping a separate mobile-optimized web app for situations where that approach works better than native. Authentication is email-and-password based. It must support: • Password reset • Account verification via email • Multi-language support Clean, well-commented, and scalable code is important throughout the project. Please keep the UI modern and lightweight, and ensure all endpoints are protected against common threats (JWT, rate limiti...

Fix Broken Backend Deployment for Live E-commerce Site URGENT — React + FastAPI/Node + MongoDB My e-commerce website is live but login, payment, and orders are broken because the backend was never deployed properly. Need an experienced full-stack developer to fix this in 1–2 days. Current Setup • Domain: (live) • Frontend: React (Create React App) — already deployed on Vercel • Backend: FastAPI / Node + MongoDB — NOT deployed (code is in GitHub) • Originally built on: Emergent AI, then exported to GitHub • Integrations: Razorpay, Google OAuth, SendGrid The Problem REACT_APP_BACKEND_URL in Vercel is pointing to the frontend domain itself instead of a real backend. So login, payments, and orders all fail. All API keys have already been ro...

We are looking for an experienced UX/UI designer and/or full-stack web development team to help evolve an existing live marketplace platform within the adult industry into a polished, scalable V1 product. IMPORTANT: This is NOT a from-scratch build. The platform already exists with a solid technical foundation and live functionality. Another developer has reviewed the codebase and confirmed the architecture/foundation is strong and workable moving forward. Current live functionality includes: • Account signup/login • Service provider profiles • Image uploads • Search/filter system • Subscription functionality • “Available now” functionality What we now need is the next evolution of the platform: • Complete UX/UI redesign and elevated visual...

My + MongoDB store holds about half-a-million product pages and I have roughly $400 to devote to tightening its technical SEO so Google can crawl, understand and rank the catalogue far better than it does today. What I need is a hands-on specialist who can dive straight into the codebase, server configuration and deployment pipeline, then implement the changes that move the organic needle. The focus is purely technical SEO: aligning every part of the site with Google’s organic guidelines and lifting overall search-engine rankings. Key deliverables • Full technical audit of the live site, highlighting bottlenecks that keep Googlebot from accessing, rendering or indexing pages efficiently. • Implementation (not just advice) of the top-priority fixes—structured da...

I’m building Pahle as a place where people can connect with each other in real time. The core feature I need you to deliver is a seamless live chat / video environment that works inside a modern web interface and scales to thousands of concurrent users. Here’s what matters most to me: • Real-time video and audio powered by reliable tech such as WebRTC (or another proven alternative you can justify). • Text chat running alongside the video stream so participants can share links or quick notes without leaving the call. • User accounts with secure sign-up, login, and password reset; social-login options are a plus. • A clean, mobile-responsive UI that feels as fast on phones as it does on desktop. • Backend that can grow: Node.js, Python, or Go w...

I’m wrapping up development of Offro, a hyper-local deals and offers app built with Flutter, FastAPI, and MongoDB. Most core functions are live—OTP login, Google-Maps-based store discovery, reward wallets, QR redemption, merchant and admin panels, and Firebase push notifications—yet the Flutter layer still needs a final round of polish before we can push to production. Here is what I need from you: • Refine the user interface so screens feel consistent, modern, and visually crisp. • Restructure navigation where flows feel clunky, ensuring back-stack behaviour and deep links work flawlessly. • Hunt down and fix the load-time and responsiveness issues that are slowing the current build, especially on the store listing and deal-redemption screens. &bul...

I need a clean, well-tested Python pipeline that listens to our MongoDB (DocumentDB) product collection, transforms each incoming SKU document, and pushes the result into Apache Solr so the search index is always in lock-step with the source data. What the transform must do • Enrich taxonomy on two fronts: category as well as attribute level. • Keep only English content for now, but structure the code so Spanish or French could be switched on with minimal effort. • Filter out the fields we don’t want surfaced—specifically the SKU number, product description and price—while leaving all other data intact. • Merge duplicates that share the same SKU logic we will provide. Runtime behaviour The service should behave like a sink connector: near...

ResolveNow is a community-driven problem-solving web application that must be built on the full MERN stack with Tailwind CSS for styling. The core flow is simple: residents post local issues, departments review them, track progress, and finally upload proof that the job is done. Everything needs to run smoothly on both mobile and desktop. Key application flow • Auth: secure registration / login with JWT, clearly separated User and Admin roles. • User post section: a resident fills a form, writes a description, and attaches one or more images; no categories or tags are required in this first release. • Complaint management: Admins see an inbox of new issues, update status (Pending → In Progress → Resolved), and can export a concise report of all resolved case...

I want to ship a full-featured mock interview platform where students and job seekers can log in, pick an HR, Technical, or Behavioral session, and face dynamic AI-generated questions alongside a bank of pre-defined and admin-curated ones. After every answer the model should evaluate wording, depth, and communication style, then return a numerical score plus natural-language feedback and concrete improvement pointers. Users must see their scores trend on a personal dashboard and revisit any past session. Two roles are enough on day one—Students/Job Seekers and Admins—so the admin panel needs controls to create or edit question sets, toggle AI generation on or off, and review platform analytics. Tech-wise I am leaning toward React or on the front end, Node.js with Express (or...

Take My App To 100% My cross-platform app is already live on both the App Store and Play Store and generally runs well, but a handful of finishing touches are holding it back from perfect. I need someone who can jump into an existing codebase and knock out the last few issues so the product feels rock-solid to every user. I can help you with Claude subscription. Key areas that need attention • iOS voice feature – the functionality is coded but the permission handshake is failing on some devices, so the microphone dialog never appears. • Backend stability – the Node.js API on AWS (EC2 + MongoDB Atlas) goes down intermittently and response times spike under load. I want logs cleaned up, memory leaks traced, and sensible auto-scaling or monitoring put in place. •...
