The operator behind the products.

Software engineer in Bengaluru, India. I build production systems end to end — product surfaces, money movement, real-time state, data sync, workflow automation, and the recovery paths behind them.

§I

I work as a founding engineer — owning product surfaces and the load-bearing systems underneath them: payments, real-time coordination, timed attempts, data sync, admin tooling, and production recovery paths.

Most of my time goes to AfterBoards and AfterGrad, exam-prep products I build as the sole engineer on one Turborepo monorepo. The work is in the systems: reconciliation-safe payouts (idempotent settlement against Cashfree, holding ambiguous gateway failures until reconciliation, with a ~30-minute Razorpay→Cashfree failover during a live outage), a multi-provider AI question pipeline — versioned prompts, automatic fallback, batch generation/review — that cut question creation from days to ~30 minutes, and a timed exam engine with resumable attempts, server-authoritative scoring and section-wise analytics that has served 100,000+ exam attempts. Around that I take on hard problems in messy real-world domains involving concurrency and distributed systems: logistics and GST billing, pharma ERP sync, on-demand commerce — see the full work record.

I care about shipping, and about writing down what I learn along the way. Based in Bengaluru, India.
