Soner Yeşilay

I'm a software developer who builds end-to-end products — from backend APIs to frontend UIs — with a strong focus on quality and maintainability. I also contribute on the QA side with solid test design and automation where it adds real value. Currently working as a Test Automation Engineer at Hugin Ödeme Sistemleri. Feel free to explore my GitHub and Medium profiles or get in touch!
