01About

I have spent 8+ years turning complex data into interfaces that feel instant. I care about the details users never notice — the 480ms that disappeared from a page load, the polling loop that stopped hammering a backend, the release that shipped on a Tuesday afternoon without anyone holding their breath. I lead with architecture, measure everything, and like making whole teams faster.

03Impact

Numbers I’m proud of.

Frontend work is easy to call “polish”. I prefer to point at the dashboards: speed, load, revenue and people.

Fresh data. 90% less load.

A live model of the polling rework I shipped at Datadog. Both clients watch the same endpoint — flip the strategies, hide the tab, push an update, and watch the request count.

06Arcade · after hours

I also make games.

After hours I’m building browser games — game loops, canvas rendering, and squeezing a smooth 60fps out of the web platform. They’ll live at their own address; the mini-game on the right is a warm-up.

  • Canvas & game loops
  • Playable in the browser, no install

Warm-up round: move your mouse over the screen to take over the paddle.

07How I work

Five things I believe.

  1. 01

    Measure, then optimise

    Performance work starts with a trace, not a hunch. I budget Core Web Vitals like any other product requirement.

  2. 02

    Fast is a feature

    Every 100ms is felt by millions of people. Latency, jank and layout shift are bugs with a user attached.

  3. 03

    Types are documentation

    A good type tells the next engineer what the code means. A great one makes the wrong thing impossible to write.

  4. 04

    Ship small, ship often

    Trunk-based development, feature flags and tests people trust. Releases should be boring.

  5. 05

    Leverage, not heroics

    Platforms, tooling and AI-assisted workflows that make a whole team faster — not just me.
