/// HELLO, WORLD!

©2026

I’m Rohit, a full-stack developer based in India, currently building scalable web apps and the APIs behind them at Shellel.

I’m a software engineer with a strong focus on building modern, scalable, and performance-driven web applications, front to back.

I work across React & Angular on the frontend and Node.js / NestJS APIs on the backend — with real-time features, caching, and AI built in.

    Full-Stack Developer Intern

    Shellel · Remote, India

    May 2026 — Present

    Moved the company's public pages — food database, blog, features, and static pages — from Handlebars to Angular SSR with client hydration, putting the whole public site on one rendering stack without changing any URLs. Wrote the backing REST/JSON APIs in Node.js (NestJS) with MongoDB/Mongoose so each page loads from a single request, owning the backend data flow. Set up a layered cache (CDN edge → SSR → in-memory → MongoDB) so traffic spikes and crawls rarely hit the database, and integrated Google Analytics 4 with environment-specific config to keep dev and production tracking separate.

  • Parkcade

    Jan 2026

    A real-time parking management system with role-based access (OpenFGA) and the booking logic behind slot reservations. Added Redis caching and tuned PostgreSQL queries to keep slot management responsive under concurrent load.

  • QuizForge

    Mar 2026

    A serverless quiz generator that turns a single user prompt into a full assessment using Google Generative AI, with Firebase handling hosting and real-time data.

  • LLM Gateway

    Planned

    A single API endpoint that pools free LLM API keys and lists every model each key can reach across providers, then automatically rotates and falls back when one is rate-limited or down. Configurable priority with fully automated failover.

  • Scalable NestJS Architecture

    Planned

    A production-grade NestJS backend blueprint — modular domains, queue-backed jobs, and layered caching built to scale cleanly. Multi-tenancy with per-tenant data isolation is next on the roadmap.
