  Avrupa Çocuk platform

  A platform connecting specialists and parents across a multi-branch rehabilitation clinic chain: a Java 25 and Spring Boot 4 backend with six user roles, a Flutter client, and separate deployments per country so regulatory boundaries stay real. I also run the organisation's Instagram and its ad campaigns.

  Triage

  A pipeline that takes messy customer input and turns it into structured data: an urgency score, a category, a two-line summary. When something is urgent, the webhook and the alert e-mail go out on their own.

  Chess, from scratch

  Chess with all its rules and no chess library: board model, move generation, check and mate detection, and a minimax search with alpha-beta pruning over a tile-based board. Java first, then ported to JavaScript so it runs in the browser. You can play it on this site.
