About

I've been writing software for about 7 years, mostly in fintech and crypto . The stuff I work on tends to be the stuff that really can't break: wallets, ledgers, transaction pipelines.

Elixir

Elixir is my main tool. I like OTP, I like supervision trees, I like knowing that when something fails it fails in a predictable way. I've built GenStage pipelines, circuit breakers, retry logic, all the patterns you reach for when you're integrating with flaky blockchain nodes or third-party APIs that have opinions about uptime. I also write Go and TypeScript when it makes sense. I'm the kind of engineer who wants to understand how things actually work under the hood, not just get them working.
