About Ugur

I am a results-driven Embedded Systems Architect with over 5 years of experience at the intersection of high-performance software engineering and Cybersecurity. I specialize in building resilient, mission-critical systems where safety and security are not just features, but the foundation.

My expertise lies in designing complex architectures for Automotive, Marine Robotics, and Industrial IoT, combining deep-level firmware development with a 'hacker mindset' to identify and mitigate vulnerabilities before they exist.
