Hi, I’m Abhinav

15 yrs · Java · distributed systems · high-reliability domains

I build Java systems for high-stakes domains: payments, pharma, and most recently the ground-control rooms that keep satellites talking to Earth. Curious by default, I turn tangled requirements into software that holds up in production.
