Skills

Grouped by area, without made-up skill levels. Technologies used in my projects link to them.

Frontend

Most of my daily work: React with TypeScript and the TanStack libraries, styled with Tailwind CSS. I have also shipped projects in Vue, Nuxt and Angular.

Backend

REST APIs and server-rendered apps: Kotlin with Spring Boot and Elixir with Phoenix at work, Node.js, Python and PHP in earlier jobs and projects.

Mobile

One Kotlin codebase for Android and iOS, with shared UI in Compose Multiplatform.

Data

Relational and document databases, query tuning, and ETL pipelines that move data between systems.

AI

I develop with AI coding agents every day, through the whole project: planning, implementation, tests, code review and deployment. I make the decisions and review every change, and I maintain context files, skills and hooks so agents follow each project's rules and do not repeat mistakes. I also trained neural networks for my master's thesis and integrated the OpenAI API into products.

DevOps and testing

Containers, CI pipelines and a self-hosted home server for my demos, plus unit and end-to-end tests with accessibility checks.
