Hi, I'm Mehmet
Backend-focused engineer specializing in Java, Spring Boot & microservices. Building scalable backend systems and event-driven architectures.
About Me
I'm a backend-focused Software Engineer with a strong passion for building scalable, high-performance systems. I specialize in Java, Spring Boot, and microservices architecture, and I enjoy solving complex distributed-systems problems.
I graduated from Adana Science and Technology University in 2020 with a Bachelor's degree in Electrical and Electronics Engineering. Since then, I've been building backend systems at fintech and AI companies across Türkiye and the US.
I believe in never stop growing and constantly seek opportunities that push me further.
