About

I started out as an environmental engineer top of my department at Marmara University. In 2022, I decided to be a Software Developer. Since then I've shipped production software for a 7M user crypto exchange, an auto financing platform, and blockchain clients across Europe. Based in Istanbul, fluent in English (IELTS 7.0), and at home in remote, international teams.
