Hi, I’m Tseko.

At Amsterdam UMC’s Department of General Practice I explore how LLMs and other modern AI can help primary care, and, as an infrastructure engineer, help decide how its databases and systems fit together. I also build secure data pipelines for the Netherlands Heart Registration.

Before that: a PhD on robust validation of clinical prediction models, and a decade of software engineering. I like using curiosity to improve everyday life, one step at a time.

Federated learning across four hospitals Four hospitals each train on their own patients. Only model updates travel to a shared model in the middle, which is merged and sent back. Patient data never leaves its hospital. shared model Hospital A Hospital B Hospital C Hospital D model updates merged model
patient data never leaves its hospital Federated learning, as in my TAVI work.

Stay awhile and listen.

Storytelling reveals meaning without committing the error of defining it.

  1. The bot

    School kept getting in the way of an MMORPG, so I wrote a bot to play while I sat in class. It levelled up faster than I did, and taught me how computers work.

  2. Competitive programming

    Contests in C, where code has to be right and fast.

  3. Maths competitions
