Started programming as a young boy on a Commodore 64 using the Logo language.
Used a variety of languages before settling down on TypeScript/JavaScript and Elixir to do fullstack development with Phoenix (for traditional web apps/backends/APIs) and Vue 3 + Tailwind CSS (for SPAs).

Continually learn new things, right now looking into domotics and the new AI techs.
