DEMIRAY

role: full-stack software engineer

location: Istanbul, Türkiye

I build web platforms, mobile products, developer tools, and data workflows. I’ve spent more than eight years moving from enterprise systems to blockchain research, developer relations, and products I own end to end. AI tooling supports the work; engineering judgment still drives it.

Products running in production

Two products I took through product decisions, interface work, backend systems, and release.
