About

Portrait of Dmitriy Leybel A childhood photo on horseback

Born in Kiev, Ukraine. Moved to Los Angeles at five and stayed for a couple of decades of pleasant weather before Oregon. AI/ML engineer, data scientist, statistician.

I work on knowledge systems and language models — building them, teaching them, and deciding when not to use them. Consultancy is Prudent Patterns; the writeups live on this site.

These days I build systems, write about them here, and get outside when I can.

Otherwise

I absolutely love the outdoors and try to get out as often as possible. Sometimes the laptop comes along for the ride, but usually not.

I am also an avid enjoyer of Corgis. A corgoisseur, one may say.
