Ashwin Gopalsamy

Hey! I'm Ashwin. I build the infrastructure behind global payments.

I work from home; on a countryside region wrapped in coconut groves, close enough to the Western Ghats that the weather has opinions.

I'm a Staff Engineer at Pismo, a Visa company working on sub-second high-throughput distributed systems. Previously, built core-banking stuff.

This fall I start my Masters in AI at UT Austin alongside my work.

Off the clock, I'm happiest around good machinery and cars, or absorbed in technology, anthropology, old history, and long-form work of almost any kind. Here's the library of stuff I love, photos I take and cafes I try and more.
