// 03about.mdconst me = {…}

Software developer, 3+ years in. I write code that has to survive production traffic, junior engineers, and my own future self.

I work across the stack — from low-level systems to pixel-perfect interfaces — and I care about the small details: cold-start times, error budgets, and the way a button feels under your finger.

Currently obsessed with developer tooling, real-time systems, and making the boring parts of software delightful.
