Computer Engineering graduate building enterprise-level Java & Spring Boot microservices at Softtech. Passionate about clean code, cloud technologies, and AI/ML.

01.About

Who I am

I'm Uğur — a Computer Engineering graduate from Fırat University, passionate about building efficient and scalable software solutions.

I started my journey as an Associate Software Engineer at Turkcell, working on real-world enterprise projects. After graduation I joined Softtech as a Junior Software Engineer — within a year and a half I was promoted to Software Engineer. For over 3 years I've been contributing to the design, development, and maintenance of enterprise-level software products for İşbank.

My core stack is Java, Spring Boot, Microservices, and SQL, while I also explore cloud technologies and AI/ML applications. I hold a Mini MBA certificate and completed a Softtech AI Bootcamp, plus online specializations in Java engineering (Duke) and Machine Learning (Stanford).
