    It is my college final year project Basis. 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. Once the back-end foundation is solid, we’ll move to the React front-end. I’d like to see the following three features come to life in our initial sprint: • Fresh, responsive user interface skeleton that sets the design language • Core...

The mobile build must compile cleanly for both iOS and Android, while the web version should feel like a first-class responsive application on desktop screens. Core scope • Design and implement a scalable, secure database schema (SQL or NoSQL—convince me which fits best) that can comfortably support thousands of concurrent support tickets. • Build a robust back-end API layer (REST or GraphQL) with authentication, role-based permissions, logging, and sensible test coverage. • Develop the front-end as a hybrid app that packages for iOS, Android, and the web without code divergence.
