👤 About

About Ryan Kapoor

I’m an independent full-stack engineer with 10+ years building products that scale. I’ve worked at Google, Stripe, and Monzo, and now I take on a select number of client projects each year where I can have real impact.

I specialise in Go and React, with deep experience in distributed systems, cloud infrastructure, and performance engineering. I work best with technical founders who need someone who can move fast without breaking things.
