NoSQL Couch 和 Mongo Jobs

Our shopping site is already up on a React-Node-MongoDB stack; now I need an experienced developer to take it over the finish line. Your main focus will be sharpening functionality, with special attention to robust search and filtering so customers can locate products quickly and intuitively. While you’re in the codebase, I also expect you to hunt down lingering bugs, tighten performance, and give the interface a final polish so it feels modern and consistent across devices. You will be working in a familiar environment—React (hooks, context or Redux), Express API, and MongoDB Atlas—so solid experience with that trio is essential. If you can blend in UI frameworks like Material-UI or Tailwind without bloating the bundle, even better. Key deliverables • Functional...

I’m building a full-stack invoice manager and need someone who can take it from concept to a polished, production-ready web application on the MERN stack. The core flow is straightforward: a user signs up with a traditional email-and-password form, completes a one-time company profile, and from then on every invoice they create automatically applies that branding. Here’s what I need you to deliver: • Secure authentication (email + password) with hashed storage, JWT sessions and basic password-reset flows • A responsive React dashboard that works smoothly on mobile, tablet and desktop, styled with clean CSS (Tailwind or plain CSS-in-JS is fine) • Invoice creation, live preview, PDF generation and download • A simple table to view past invoices with se...

I’m expanding ReviewyAI from a promising prototype into a production-ready, autonomous code review engine. The immediate focus is twofold: first, integrating GPT-3 (with the option to swap in OpenAI or Anthropic APIs later) so the reviewer delivers highly accurate suggestions; second, re-architecting the backend so the system can serve a growing number of simultaneous users without losing speed or reliability. Here’s how I picture the collaboration working: • Frontend evolution – You’ll design and refine reusable components with Tailwind CSS, ensuring the interface feels fast and intuitive on any screen size. • AI-driven analysis – Wire GPT-3 into the Node/Express layer to inspect incoming code, score potential issues, and return actionable feed...

I’m building out a new React front-end and now need the server side to catch up. The priority is a robust Node.js backend that exposes well-structured RESTful endpoints returning clean, predictable JSON. The data layer will live in MySQL, so you’ll design the schema, set up migrations, and write queries or use an ORM—whichever keeps performance high and code readable. Although Laravel experience is welcome and I do plan to introduce a small GraphQL layer later, right now your main focus will be the REST API: authentication (token-based), role management, pagination, filtering, and solid error handling. Clear inline documentation and a concise README or Swagger / OpenAPI file should accompany each route so the React team can plug in immediately. I’m flexible on tim...

I already have a fully-built Node.js project (Apostrophe 3 CMS, v 4.8.0) zipped and ready to go. All I need is a smooth deployment to my Hostinger Business Node.js plan so the site becomes publicly accessible on my domain, no code changes, no feature tweaks. Key context • Node version on the server is 22. • Auto-deploy won’t work with ApostropheCMS, so it must be set up as a custom Node.js app. • I do not have SSH enabled on the account. Instead, I can upload through Hostinger’s File Manager and am looking for an alternative workflow that accomplishes the same npm install → npm run build → npm run prod sequence. The archive you’ll receive already contains , package files, all modules, views, public assets, scripts and ; node_modules is i...

I run a RO-based tech agency and I need a technical partner to take over running it. This post is specifically for technical freelancers and consultants who've already been running their own show — winning clients, scoping projects, managing delivery — and want to do it with an existing agency, team, and client base instead of building from zero. If you're a developer or architect who outgrew just writing code and started running your own consultancy, managing clients, and subcontracting to other devs — this is your role. This starts as a freelance engagement with a 2-week paid trial. If it works, this becomes full-time with a base salary + commission on new business. Partner-track, not employee-track. You get: an existing team of developers, active clients, and...

I need a part-time full-stack developer who is comfortable owning both the machine-learning pipeline and the web stack around it. The core assignment is to build and maintain a web application whose main feature is a ChatGPT-style chatbot, so practical experience creating, fine-tuning, and deploying conversational ML models is essential. You should be able to: • Design, train, and iterate on machine-learning models that power the chatbot, keeping latency low and responses relevant. • Wire those models into a modern web front-end and a secure, scalable back-end. Whether you reach for React, Vue, or another JS framework on the front and Flask, FastAPI, Node, or similar on the back is up to you—as long as you can justify the choice and move quickly. • Handle end-to...

I’m ready to commission an end-to-end system that streamlines every core activity in my restaurant. The platform must let staff register customer orders effortlessly—whether those orders come from table service, the main cashier, or our Drive-Thru window—and route each ticket to the kitchen in real time. For payments, the system needs to accept cash, bank cards, and mobile wallets, closing each bill against the correct order source with minimal clicks. Clear audit logs are essential. On the staffing side, I want to create roles, assign granular permissions, and distribute daily tasks so each employee sees only what they need to see. Accurate, filterable financial reports are a must. At minimum I expect revenue, expense, and net-profit dashboards that can be exported to...

My MongoDB Atlas cluster connects instantly through Compass, yet the same connection string refuses to cooperate inside my React project. The URI is tucked away in an environment variable, but at runtime I receive a generic “connection string” error and no data appears. I need someone to: • review how I’m importing the .env values and verify the string syntax • confirm the driver / library I’m using from the React side (or its Node-based API layer) is configured correctly for an Atlas URI • diagnose any authentication, whitelisting, or network nuances that Compass might mask • deliver a working example and a brief explanation so I can replicate the fix across environments Once the project builds and fetches data from Atlas without throwi...

I’m kicking off the creation of a brand-new web application and need a programmer who can guide the project from first commit to production release. You’ll take my concept and implement both the user-facing front end and the server-side back end, then deploy everything to a live environment. You are free to choose a modern tech stack—React, Vue, or plain JavaScript on the front end; Node.js, Django, or a comparable framework on the back end—so long as it results in clean, secure, well-documented code. Database design, API integrations, user authentication, and responsive UI are all part of the scope. I already have wireframes and a feature list ready to share once we start. Deliverables • Fully functional web application that matches the provided feature li...

I already have a production-ready library management platform running on a front end with a NestJS API, containerised with Docker and deployed on AWS (files are stored on S3). The missing piece is a compact student-tracking module that: • scans a student’s unique QR code on entry and exit • records the exact timestamps, the library section they visit, and calculates total duration of stay • appears seamlessly inside the current interface (no separate UI) The work involves adding the relevant pages/components in , extending the NestJS services and database schema, wiring in any AWS resources you need, and shipping the whole thing with full Jest unit/integration tests. Code quality must match the existing clean, typed, linted codebase; every new container or scr...
