Full-Stack Engineer · RGIPT '27

Building systems that scale — from voice-first AI pipelines to multi-tenant SaaS platforms.

About

I'm a 4th-year IT student at RGIPT who builds and ships full-stack products. I care about the details that actually matter in production: query performance, caching strategy, auth flows that don't break, and APIs that are consistent under load.

Currently focused on backend engineering, distributed systems fundamentals, and competitive programming.


Projects

TrueTone — Voice-First AI Feedback System

React · TypeScript · Node.js · Express · PostgreSQL · Groq/Openrouter APIs

A full-stack platform that processes audio sessions end-to-end: transcription → LLM analysis → sentiment + topic extraction → summarization.

What I built and why it was non-trivial:

  • Handles 100+ daily audio sessions with automated transcription pipeline; had to think carefully about async processing to avoid blocking the request cycle
  • PostgreSQL indexing strategy reduced query latency by 35% under real query load
  • Ran sentiment analysis + summarization across 500+ records via Openrouter/Groq — had to manage rate limits, retries, and cost-aware batching
  • JWT auth + role-based access control with clean separation between user roles

NAMS — News Agency Management System

React · TypeScript · Node.js · Express · PostgreSQL · Prisma · Redis · BullMQ

A multi-tenant SaaS platform where each newspaper agency gets isolated data, billing, and customer management — fully production-deployed.

What made this architecturally interesting:

  • Multi-tenancy at the data layer: had to design schema with proper tenant isolation without sacrificing query performance
  • Redis caching + BullMQ background workers to handle subscription billing jobs async, decoupled from the request path
  • CDN setup (AWS CloudFront + Cloudinary) brought asset load times down 40% — measured before/after with Lighthouse
  • Deployed across Vercel (frontend) + AWS EC2 (backend); set up proper env management and zero-downtime deploys
