02 / A BIT ABOUT ME
Curiosity is the start.
Making it work
is the
interesting part.
Runiir Beltran ↗
I like working across the whole problem: the interface someone uses, the logic underneath it, and the system that keeps it running.
My personal work moves between product development and machine learning research. Sometimes that means building a publishing tool. Sometimes it means asking how much context a language model really needs.
I also take care of the less visible work: deployments, monitoring, and making the next change easier to ship.
