Welcome

Hey there! I'm Efe, a software and AI engineer who loves building things that make life more interesting.

Currently working at ASML as a Software Engineering Intern, and serving as CTO at Jewelss.co where we're building a comprehensive digital asset trading platform. I'm also a Teaching Assistant at the University of Groningen for C++ and Reinforcement Learning courses.

My work spans reinforcement learning, computer vision, and full-stack development—from training AI agents to building production-ready applications that solve real problems.

What I Do

  • Mobile Development

    Building native iOS applications with Swift/SwiftUI, focusing on performance and user experience.

  • Backend & Infrastructure

    Designing scalable systems with Kubernetes, Docker, NestJS, and cloud platforms.

  • AI & Machine Learning

    Developing intelligent systems with PyTorch, TensorFlow, and reinforcement learning algorithms.

  • Systems Programming

    Low-level programming with C/C++, optimization, and understanding how things work under the hood.

About me

I can't play games for more than 10 minutes anymore—my brain just wants to figure out how to make AI play for me instead. That's how I approach most things: I get curious, I tinker, and I look for clever shortcuts.

I love getting lost in a problem, especially if it involves computers or code. New programming languages? Bring them on. Weird technical challenges? Even better. I'm always chasing that "aha!" moment when something clicks or when I find a solution nobody else thought of.

If you're the kind of person who likes talking about wild ideas, cool projects, or just wants to geek out about tech, I'm always up for a chat.
