About
I'm Raj — a backend engineer who likes the problems that show up when software meets money, concurrency, and scale.
I work as a Software Development Engineer II at Togopool, a multi-tenant mobility SaaS platform. My first real production task there was a payments incident: passengers were being charged, drivers weren't being credited, and the answer was buried in a large, interlinked codebase. Tracing that failure — and then redesigning the wallet system so it couldn't happen silently again — set the tone for the work I care about: systems where correctness is the feature.
Since then I've built payment infrastructure across five providers, a Redis-based distributed locking system for concurrent seat reservations, fraud detection for driver incentives, and routing that cut our third-party API costs by 75%. I was promoted to SDE II in January 2026, and I own my work end to end — design, implementation, deployment, and the on-call that follows.
I hold a B.Tech from Maulana Azad National Institute of Technology (MANIT), Bhopal, and an AWS Cloud Practitioner certification. I'm currently deepening my system design and architecture skills — the Architecture Lab on this site is where I work through those ideas in public.
