About

Background

I'm Mehmet Berke Karadayi, a Software Engineer at Coinbase and an Electrical Engineering graduate from UBC. I build reliable product systems across frontend architecture, real-time interfaces, and AI-assisted engineering workflows.

My work spans React, TypeScript, GraphQL/Relay, WebSockets, and LLM-powered tooling. I care about turning ambiguous technical problems into polished, maintainable software—with ownership, collaboration, and craft.
