Building scalable systems by day — riding infinite roads by night.
Software Team Lead at Werover. Mechatronics-turned-engineer specializing in mobile apps, IoT platforms, backend architecture and cloud-native deployments. Passionate about energy efficiency in code and on the saddle.
About
Engineering at the intersection of
hardware and software.
I started with mechatronics engineering at Manisa Celal Bayar University (GPA 3.32/4.00), which gave me a rare dual perspective: I understand both the silicon and the stack. From lift control systems to IoT platforms, from embedded C++ to cloud-native Node.js, I build things that work at scale.
Outside the terminal, I'm a semi-professional cyclist obsessed with long-distance rides — the same discipline that keeps me optimizing for endurance over sprints in every system I build.
