About me▍

tl;dr — a nerd who ships production software for web and mobile.

I'm a full-stack & mobile application engineer with 12+ years in IT — the kind who reads the changelog, keeps a terminal open, and genuinely enjoys a good refactor.

My playground spans Java & Spring Boot services, Node.js and PHP backends, and frontends built with Svelte and Vue.js. On mobile I ship Android apps in Kotlin and cross-platform builds with Flutter.

I care about clean architecture, fast feedback loops, and software that stays maintainable long after launch day — not just demos that look good in a sprint review.
