Shipping backend systems that don't fall over — slot locking, RBAC, rate limiters, the unglamorous stuff that has to actually work.
I'm Rohit — a backend dev who'd rather debug a race condition than write a slide deck about one. My comfort zone is the backend: designing APIs, wrangling databases, and making sure the thing scales before someone finds out the hard way.
I've built a health-tech booking platform with slot locking under real concurrency, published an npm package that developers actually use, built hybrid rag ai agents, and shipped a mobile app to the Play Store — end to end, my code, my bugs, my fixes.
Actively looking for SDE intern / fresher roles where I can keep shipping things that need to stay up.
Worked on a health-tech booking platform, building slot-locking logic to stop double-bookings under real concurrent load and role-based access control (RBAC) to keep patient and provider data properly separated.
Built and shipped front-end features in React, translating designs into responsive, production-ready UI and working directly with the existing codebase and team workflow.
A production-grade RAG chat app on a TypeScript-native stack — LangChain.js, LangGraph.js, ChromaDB, Elastic Search, and transformers.js with cross-encoder reranking. A deliberate choice over Python to keep it consistent with the rest of my stack.
