ai engineer at coop. shipping ai apps by day, going deep on how language models actually work by night, running small saas in the in-between hours.
this site is where i think out loud. long-running notes on the subjects i'm in the middle of, smaller asides on the side, and a record of the things i'm shipping.

ai engineer at coop
shipping production ai for switzerland's largest retailer. mostly the engineering layer underneath the model — evaluation, observability, latency, the stuff that decides whether ai tools actually get used at scale.

building an llm from scratch

indie saas
language-islands.com (web, ios, android) and therapiebericht.ch — both shipped with kaan sentürk. zazaki-islands.com is a non-profit i run on my own: a place where native speakers translate and pass on an endangered language.
§ notebook
not posts — each subject is a single, growing document. sections pile up; conceptual asides sit in the margins.
