NoSQL Couch & Mongo Jobs

My e-commerce site already holds every product record in a MongoDB cluster, and I now want a Retrieval-Augmented Generation (RAG) layer that can pull that data on-demand for search, chat, and merchandising features. Here’s what I need built: • A lightweight service (Python preferred; open to Node.js) that connects securely to the existing MongoDB collection and exposes a clean retrieval interface. • An embedding/indexing routine so product documents can be vectorised and queried efficiently (e.g., with FAISS, Pinecone, or a native MongoDB Atlas Vector Search). • RAG pipeline logic that combines the retrieved product fields with a language model prompt to produce rich, real-time answers. • Environment configuration and clear instructions so I can run, exten...

Looking for a Reliable Full-Stack Developer / Partner Hi everyone, I'm looking for a reliable full-stack developer who can take over and complete an existing project.

I aim to build a truly global space where more than ninety-nine million professionals can discover one another, collaborate and grow. The core idea is simple: give users a reliable way to meet peers, share expertise and uncover new career opportunities—yet the execution must be enterprise-grade from day one. What the build involves • Full-stack development of a responsive web application (React or similar on the front end, Node.js/Go/Python on the back, with a REST or GraphQL API). • Cloud-native deployment on AWS, GCP or Azure, containerised with Docker and orchestrated via Kubernetes so the system scales smoothly as membership climbs. • A rock-solid data layer—PostgreSQL or MongoDB combined with Redis for caching—designed to accommodate hundreds of...

I have the core concept and a technical outline for a new medical platform that puts patients first, and now I need a full-stack developer to turn it into a production-ready application. Platform focus The entire experience must revolve around patients—everything from the landing pages to each dashboard screen should guide them effortlessly toward the information or action they need. In addition to the features outlined below, patients will be encouraged to stay engaged through an integrated blog section that delivers health tips and practice news. Stack and architecture • Back-end logic is planned in PHP for traditional server tasks and Node.js for any real-time components that benefit from non-blocking I/O. • A secure SQL database needs to be designed, populated, ...

I’m building a small-scale billing web app and need you to take it from idea to deployable code. The tech stack is fixed—React (hooks + functional components) on the front end, Node.js with Express on the back end, and MySQL for data storage. Core focus The heart of the system is invoice generation. Every invoice must be produced as a PDF, saved to the database, and retrievable from a client’s record. A flexible template engine is essential: I want to tweak colours, fonts, and layout without touching code and, most importantly, drop our company logo into the header of every invoice. What I expect the finished product to include • React UI for customer, product, tax and invoice management • RESTful API in Node.js/Express with JWT-based auth and basic role con...

I’m putting together a tutoring roster for students who need help across both technical and management tracks. On the engineering side, support is required for Mechanical, Electrical, and Computer Science subjects. On the business side, guidance is needed in HR, Finance, and Stock Marketing. You should be comfortable moving from calculus-heavy circuit analysis or thermodynamics to explaining financial ratios and equity fundamentals—sometimes in the same day. Clear explanations, real-world examples, and the ability to tailor depth to each learner will make you a great fit. Sessions will be conducted online, so reliable connectivity and screen-sharing tools are essential. If you have prior experience creating problem sets, mock exams, or case-based assignments, let me know; t...

Our production platform is built on Node.js and I’m looking for someone who can step in as a long-term partner to keep it healthy while steadily making it better. Day-to-day you’ll be digging into three broad areas: • Fixing bugs as they surface so the system remains stable. • Profiling and tuning performance to keep response times low, memory use under control, and throughput high. • Enhancing existing features—polishing the user interface, tightening up backend logic, and refining the data-processing layer whenever we see an opportunity. Most of the work is about improving what already exists rather than building brand-new modules, so an eye for incremental refactorings, clean code, and solid test coverage is essential. I’ll share a prioritize...
