Building a client SaaS platform

About

Grounded in fundamentals, built for production

I'm a Computer Science & Engineering graduate from Government Engineering College, Khagaria, focused on the MERN stack and, more recently, Next.js and NestJS.

Right now I'm building a production SaaS platform for an international freelance client — architecture, backend, frontend, and deployment, end to end. Outside that engagement, I've shipped four full-stack apps on my own: a real-time social platform, a role-based campus management system, a community help-matching app, and a B2B marketplace for Indian textile suppliers.

I'm also NPTEL-certified by IIT Madras in Python and Operating Systems, which keeps the core CS fundamentals solid underneath the framework of the month.

Four apps in production. One live client. Everything on this page is something I actually built and deployed — not a tutorial I followed.

React.js Next.js Node.js NestJS MongoDB PostgreSQL TypeScript Socket.io JWT Auth REST APIs

Frontend

React and Next.js interfaces that are responsive and accessible — built to be maintained, not just demoed.

Backend

REST APIs and service architecture in Node.js and NestJS, with real auth — JWT and role-based access, not a login screen for show.

Database

Schema design in MongoDB and PostgreSQL, matched to how the app actually queries data.

Deployment

Every project here is deployed — Vercel, Render, Netlify — and I own the deploy, not just the code.

Featured work

4 apps, deployed and reachable right now — each with a short case study on the problem, the architecture, and the trade-offs.

VibeConnect

Challenge: Two transports (REST + WebSocket) had to agree on state, and an unauthenticated client couldn't be allowed to subscribe to a live channel.
Technical Decision: JWT is verified at the Socket.io handshake itself, not inherited from the REST session — writes land in MongoDB before they broadcast.
Result: Real-time and REST auth share the same boundary; a dropped broadcast never desyncs a client, since a refresh always re-reads the same MongoDB truth.

CampusCare

Challenge: Student vs. admin access needed to be a real security boundary, not a UI toggle a client could route around.
Technical Decision: Role-checking middleware sits in front of every protected route, rejecting a bad role claim before the controller runs.
Result: 2 roles enforced server-side (RBAC) — an admin route rejects a student's token outright, it doesn't just hide a button.

HelperHub

Challenge: A request's status had to be a real state machine — not a field any authenticated client could set to whatever it wanted.
Technical Decision: Transitions are validated server-side and scoped to the request's owner or assigned helper, not any caller.
Result: 3-state lifecycle (open → claimed → resolved) where an invalid transition is structurally impossible from the API.

AI B2B Textile

Challenge: Hub and category needed to filter the same listings independently, without forcing buyers through a pick-one-first funnel.
Technical Decision: Hub and category are combinable filters over one listing set, addressable as real Next.js routes, not client-only state.
Result: 34 listings live across 6 categories and 6 sourcing hubs, each combination reachable as its own URL.
