Hi, I'm Nrupesh 👋
I build fast, reliable checkout and payment systems at Amazon scale.
Software Development Engineer II at Amazon, based in Madrid, Spain. I care a lot about latency and system design, and enjoy building GenAI tools. Away from the keyboard, I'm usually out running.
Happy to chat about payments, distributed systems and GenAI tooling.
