I am building a complete sports-tracking platform that works beautifully in a browser and installs on a phone’s home screen like a native app. The core of the project is a responsive website/PWA where three distinct roles—Admin, Coach/Manager, and Athlete—log in with a standard email-and-password flow to manage data quickly and securely. Each athlete profile must hold name, photos, rankings, fight history, contact details, and a private section for medical records that stays encrypted at rest and in transit. Coaches and managers need a clean dashboard to compare stats across leagues, teams, and individual fighters, while a public view shows only approved rankings and fight results. Rankings and other stats should update in real time or on a scheduled job you recom...

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 consis...

...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 course-management screens (create, edit, enroll) powered by live data • Real-time progress-tracking display that reflects the learner’s s...

...calls inside the MGX stack. Second, I have not yet committed to a specific datastore because the choice has to serve the AI that will sit on top of it. I need guidance on designing a schema—whether that ends up being SQL, NoSQL, or even a hybrid cache layer—that lets the AI fetch, store, and update information efficiently enough to answer user requests in real time. Finally, the intelligence layer itself: I’m aiming for an “informative and analysis” AI module. Think NLP that can interpret user prompts plus analytical routines that can surface insights from the stored data. Model selection, pipeline design, fine-tuning, and integration back into the app are all on the table. Deliverables • End-to-end REST API implementation connected ...
