About Reon

Seasoned technology leader and entrepreneur with 10+ years of experience building complex technology products from the ground up, spanning AI, hardware, software, and embedded systems. I combine deep technical expertise with a strong product and business sense, helping organizations turn ambitious ideas into scalable, real-world solutions.


As fractional CTO, I partner with startups and scale-ups that need senior technology leadership without a full-time commitment. Whether it's defining product architecture, leading development teams, or navigating the path from MVP to market. I bring hands-on experience and strategic clarity.


My track record includes co-founding Mentech, where I led the development of an MDR-certified AI platform combining wearables, physiological data, and machine learning. Scaling the tech team to 25+ people over 10 years. I have hands-on experience with hardware/software co-design, AI integration, and bringing certified products to market in regulated environments.


I'm available for fractional, interim, or advisory engagements, with a particular interest in companies building at the intersection of hardware and intelligence.
