Hi, I'm Zak.

I’m a staff engineer working on Realtime data problems at Ably, previously Unweave and Attest. I spend much of my time leading teams, upskilling engineers, and solving scaling problems — team, tech, and organisation.

I’ve been writing here on and off since 2016 — posts, talks, and opensource projects. The common thread is the interesting bits at the edges, where the abstractions stop holding up.

Marathon runner, code lover, seasoned reviewer of PRs. If anything here resonates, I’m easy to find — let’s solve hard problems together.
