I build products, and the automation that gets them out the door.
I'm also working on something about AI for small businesses. If that sounds like you, get in touch.

Services
Currently booked full-time. Open to short advisory work if interesting enough.
How we can work together.
You need another senior pair of hands.
I join your team for a few months and ship with you.
Mobile, backend, payments, and the CI and AI tooling that holds it all together.
Recently: I moved a team's iOS builds off Xcode Cloud and onto GitHub Actions. Checks on every PR, a build every night, a release whenever you tag.
You want someone to look at it with fresh eyes.
A short review with a clear scope.
Architecture, mobile and backend, how you release, and where an AI agent could save your team time.
Recently: I set up bots that open, approve and merge their own pull requests, and a single CI gate for a whole monorepo.
You need someone to lead engineering.
Part-time lead while you hire, or while you grow.
How often you release, code standards, testing, and hiring the people who'll take over.
Recently: Nightly end-to-end tests that create their own test accounts, so nobody has to set them up by hand any more.

About
I studied telecoms engineering and ended up coding. I've lived in Wrocław and London, and came back to Marbella. When I'm not automating something, I'm probably cooking, lifting heavy things or wandering around somewhere new without a map.
