About
Six years building and running payment and logistics systems for Sri Lankan and Singaporean companies. I work mostly in TypeScript and Go, and I care more about what happens at 3am than what happens in the demo.
Most of my work has been on systems where downtime costs money directly, so I have spent as much time on observability, rollbacks and on-call runbooks as on features.
