About

Backend engineer who likes building systems that scale — and actually hold up when they do. Spent nearly 4 years at Urban Company working on the kind of infrastructure that quietly powers everything: re-architecting the multi-category checkout across 7+ microservices with zero downtime, building Kafka + FAISS-powered recommendation engines that moved homepage engagement by 13.7%, integrating AI models into conversion pipelines, and hardening payment systems on the road to IPO. Real scale, real ownership. Now at Fello, building backend infrastructure from the ground up — communication systems, AI integrations, multi-agent orchestration. Early stage, high ownership, exactly the kind of engineering I want to be doing. Stack: Node.js, TypeScript, Kafka, Redis, MongoDB, AWS, distributed systems. IIT BHU '22. Petrolhead 🏎️
