About

Z. Saygin Dogu — Full-Stack Software Engineer

I’m a full-stack software engineer with over 10 years of experience building production software across fintech, edtech, and enterprise cloud platforms. Based in Dublin, Ireland.

What I Do

My core stack is Java / Spring Boot and Kotlin on the backend, with some prior Python / Django experience as well.

On the frontend, I work with TypeScript, JavaScript, React / Next.js.

I have some Flutter experience for mobile.

I’ve shipped systems running on AWS, and I’m comfortable across the full DevOps lifecycle — CI/CD, Docker, Kubernetes, and beyond.
