I'm Eleftherios, a UAV engineer and designer with deep experience in developing both fixed-wing and multirotor drones. I specialize in practical, real-world drone systems—from early design to full flight testing and tuning.

I was the Co-founder and Head Designer of Smart Flying Machines, a company focused on developing advanced UAV platforms. Our commitment to robust, real-world drone solutions led to the company being acquired by Delian Alliance industries, highlighting the strength of our work and vision.

Beyond engineering, I'm passionate about education. I'm the author of the Greek-language course Design and Development of Unmanned Aerial Systems (UAS), hosted on elearningekpa, where I teach practical drone design and system integration to aspiring engineers and students.

I also work actively as a freelance UAV expert on Upwork, helping clients around the world with drone architecture, ArduPilot and Pixhawk systems, and UAV customization for unique missions.

If you're interested in real UAV design—beyond theory and into hands-on building, tuning, and flying—you're in the right place. My goal is to help you learn what really works, and why.
