I am a passionate advocate for open-source firmware solutions, with a deep-seated belief in the transformative power of transparency, innovation, and trustworthiness. At the heart of my journey is 3mdeb, where we've cultivated a vision emphasizing user liberty, simplicity, and privacy.

Building a healthy community is paramount to me. In an era where toxic incentives can drive some communities, I believe in fostering an environment prioritizing genuine collaboration and shared growth. Through events like Dasharo Users Group, Dasharo Developers vPub, Qubes OS Summit, and FOSDEM's Open Source Firmware devroom, we aim to bring together like-minded individuals who share our vision. Our contributions to platforms like OpenSecurityTraining2 further underscore our commitment to knowledge sharing and community building.

As the founder of 3mdeb, my role is not just about overseeing operations but also about embodying the company's vision and mission. From strategic decision-making to understanding the intricacies of our technology, every day presents a new challenge and an opportunity to drive our vision forward.

Beyond my professional pursuits, I'm a casual chess and bridge player, an avid reader, and a nature enthusiast who finds solace in the forest. My interests span across theology, philosophy, and psychology, reflecting my innate curiosity and desire to understand the world around me. Whether it's exploring new technological frontiers or delving into a philosophical text, I approach life with an open mind and a thirst for knowledge.
