About
Backend engineer, mostly payments. I like the parts of the system nobody wants to own — retries, idempotency, the queue that quietly drops things at 3am. Ten years in, and I still write the test first.

Idempotency keys, service-wide
Made retries safe across 40 services at Stripe without a coordination layer.
Writing
Idempotency is a product decision
Why the retry key belongs in your API, not your infrastructure.
How to read a flamegraph
The five-minute version I give every new hire.
About
I design brands that have to work as products — identity, type, and the interface it all lands in. Ten years split between studios and in-house teams, most recently four years at Airbnb on design systems. Independent since 2023, two projects at a time. I care about typography that survives contact with real content, and I would rather ship a smaller system that holds.

About
I build data tooling. Halden is the third thing I have shipped and the first that pays for itself. Before that: four years at Vercel, and one startup that did not work — which taught me more about pricing than the four years did.

Rowboat
Async standups. Good product, wrong market — I wrote up why.
About
I build the systems a company runs on — hiring loops, planning cadence, the spreadsheet that quietly becomes a team. Took Faire's operations from 40 people to 900, through two funding rounds and one very bad quarter. Now I work with Series A founders who are about to hire their first fifty people, usually a month or two before they think they need help.
