Ashwin Sathian.
Engineer.
The systems I've built handle $1B+ in transactions. Calm under load. Precise by design.
Seven years building things that matter.
I spent seven years at one company — growing from the engineer who shipped features to the one who designed the systems that shipped them. That depth is rare in this industry. I'm proud of it.
My work lives at the intersection of architecture and execution. I care about the systems underneath the product as much as the product itself: clean boundaries, honest tradeoffs, and teams that understand why — not just what.
