I build cloud platforms that handle millions of requests, lead engineering teams that ship fast, and occasionally break production (but always fix it before anyone notices 😅).
I'm an engineering leader who loves solving hard problems — the kind that make you stare at logs at 2 AM wondering why that worked in staging.
At Drive lah, I lead a team of 25+ engineers building a platform that handles over a million requests daily. We've cut AWS bills by 35%, sped up deployments from an hour to 5 minutes, and somehow maintained 99.99% uptime (knock on wood 🪵).
I started as a backend dev who just wanted to write clean code. Eight years later, I'm more excited about building teams than building features. There's something special about watching engineers grow and ship things they didn't think they could.
