Yusuf Akcay

I am a Full Stack Software Engineer specializing in the design and implementation of Backend Distributed Systems. My engineering philosophy is centered on building resilient, high-scale architectures that solve the problems of modern web development: concurrency, data consistency, and scalability.

I am currently completing my Bachelor of Science in Computer Science at the University of the People, where I maintain a perfect 4.0/4.0 GPA and have been named to the President's List. This follows my Associate of Applied Science in Computer Programming from Anadolu University, providing me with a balanced foundation of theoretical computer science and practical software engineering.

Outside of engineering, I'm based in Turkey. When I step away from my IDE, I'm training as a powerlifter.
