I build tools people actually use.

Software engineer working across full-stack web, machine learning and mobile. Most of what I have built started as a problem someone I knew actually had. 6 of them run right here in your browser.

Building the tooling for a coaching org

I helped run a Valorant coaching organisation, and most of what it needed did not exist. Over about a year I built the pieces one problem at a time — a public league site, then the admin work behind it, then the analysis tools coaches asked for.

  1. Underpeel

    A tournament site for a Valorant league, still live today.

  2. Valorant Kill Map

    Where rounds are actually won, plotted from match data.

  3. Lineup Tool

    A desktop overlay that reads the game and aims for you.

  4. Student Progress Tracker

    Automating the coaching report nobody wanted to write.

I am looking for internships and early-career software roles.
