About me

I've spent ten years building software that ships and stays in production. I start from a design and handle everything after it: the app, the API behind it and the server it runs on. When something breaks in any of those layers, I don't have to hand the problem to someone else.

I started on Objective-C and PHP; today I write SwiftUI and Angular. That path left me with something uncommon for a web developer: I also work with devices — ESP32, Raspberry Pi, MQTT — so a project that starts at a sensor and ends in an app does not need two teams.
