Hi 👋 I'm Çağrı, a software engineer, community leader, and educator based in Amsterdam, The Netherlands.

I work as a Software Engineering Lead at Trimble Inc. Previously, I've been building scalable solutions with Java and open-source technologies for over 16 years.

I'm passionate about sharing knowledge through FolksDev, where I voluntarily teach Java, Spring Boot, and software engineering best practices to a community of 15K+ subscribers.

About

With over 16 years of experience in software engineering, I bring a strong blend of technical expertise and leadership to my current role as Software Engineering Lead at Trimble. I specialize in shaping architectural decisions for complex, large-scale platforms while remaining hands-on in driving implementation and delivery.

My leadership approach focuses on empowering people — setting clear direction, mentoring developers, and fostering collaboration across teams. I've successfully built and led high-performing teams, balancing technical depth with strategic thinking to deliver scalable and impactful solutions.

In addition to my industry role, I actively contribute to the engineering community by organizing events, mentoring developers, and delivering Java training programs through FolksDev.
