...profiles, a real-time messaging system, and an engaging activity feed that keeps everyone up to date on posts, likes, and comments. The site has to be entirely browser-based, mobile-responsive, and built with clean, well-documented code. I’m open to the modern stack you prefer—whether that’s React or Vue on the front end, a Node/Express, Django, or Laravel backend, and a solid relational or NoSQL database—so long as it scales, is secure, and performs smoothly under load. Deliverables I expect: • Wireframes or a clickable prototype to confirm UX • Front-end implementation with responsive styling • Back-end API and database schema supporting profiles, messaging, and feed updates • Real-time or near real-time messaging (WebSo...

...database and front-end dashboard that stores and serves geotagged data (GPS coordinates and timestamped photos) for every single unit of impact. Users must be able to verify their specific contribution through a unique digital certificate or a live tracking link. Technical Requirements: Backend: Scalable architecture (Node.js, Python, or Go) with well-documented RESTful endpoints. Database: A NoSQL approach (like MongoDB or DynamoDB) is preferred to handle the rapid scaling and diverse data types (images/coordinates) required for millions of records. Security: Airtight data security and settlement logic to ensure every dollar collected is accounted for and matched to a verified event. Frontend: A lightweight, clean UI for a "Client Impact Dashboard" where corporate...

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...

I have already built a residential-focused property-management application in Google AI Studio using Nex.js. The UI is complete; what’s missing is the back-end layer that will persist property records and let me push the product live. Here’s what I need from you: • Review the existing React codebase and advise whether an SQL or NoSQL solution best fits the current architecture. I’m open to either and will follow your recommendation. • Spin up the chosen database, create the schema/collections for residential property details, and connect it to the app with secure CRUD APIs. • Configure an integration endpoint so property data can flow in automatically from other systems rather than being keyed in manually. • Walk me through deployment&m...

...services through a REST API. I already ruled out GraphQL and SOAP for now, so your focus will be on structuring clean endpoints, handling authentication, and ensuring low-latency 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....

...When a date is approaching, the owner and any assigned RTO Agent receive an in-app alert plus an SMS and WhatsApp message. Admin sees the same warnings in a consolidated panel.
