Chapter I · Now

Since November 2025, I’ve led technology for the Investor Portal at Droom.

I joined as a front-end developer in April 2025 and became Tech Lead seven months later. I shape the product’s architecture on web and mobile, guide the team, and make sure our process helps rather than gets in the way.

App

Team

Git Flow, semantic commits and Scrum, set up from scratch with the team.

Chapter II · The workshop

Tools I build after hours.

First they solve a problem of mine. Then, anyone else’s who wants them.
