Kaja Skerlj

I'm a product designer based in Berlin, building interfaces for AI from 0 to 1.

Currently, I'm a designer at *codeplain working on a spec-driven code generation tool. Before that, I was the first designer at a voice AI startup at Soniox and a designer at Sony.

I represented Slovenia at World Youth and European Championships, and later competed as a student-athlete at Lehigh University in the US, graduating with a bachelor's degree in product design and a master's in engineering.
