You’ll own the entire build: front-end, back-end, database design, third-party integrations, and cloud deployment. You should feel at home with a modern JavaScript front-end (React or Vue), a Node-based or similar back-end, REST / GraphQL APIs, and either relational or NoSQL databases. Containerised workflows, CI/CD pipelines, Git-based collaboration, and security best practices are expected parts of your toolkit.

This project focuses on the design and implementation of a distributed NoSQL database system capable of handling large-scale, dynamic data with high availability, scalability, and strong consistency. The system uses dynamic sharding to automatically partition and distribute data across multiple nodes based on data growth and access patterns. It incorporates replication and consistency mechanisms such as quorum-based replication or distributed consensus protocols to ensure data integrity even during node failures or network partitions. The project aims to balance the scalability and flexibility of NoSQL systems with the consistency guarantees of traditional databases. Performance, scalability, and consistency are evaluated under di...

    I’m kicking off a new Learning Management System and need a developer who can drive the entire build, from the first database table to the final front-end interaction. The immediate priority is the Node.js back-end: you’ll stand up a clean Express (or Nest) codebase, wire in a relational or NoSQL store, and expose secure, documented endpoints. The first API milestone is robust user authentication—JWT or OAuth is fine as long as it’s production-ready and easily extendable for role-based access later on.
