I’ve been building digital products since I was 14, driven by a deep curiosity to turn ideas into tools that solve real problems. One of my first personal projects was an AI tutor I built to prepare for Greece’s national exams. Using it daily helped me score in the top 0.1% nationwide without external instruction. I documented the journey in a YouTube video that’s now been viewed over 50,000 times. Over the past few years, I’ve contributed to open-source projects, shipped production-ready tools for startups, and participated in 10+ hackathons where I built functional apps in just days, earning several first-place finishes. I thrive in fast-paced, problem-solving environments and love creating technology that moves quickly from prototype to real-world use.

I bridge technical architecture and product vision to build impactful software solutions. My expertise spans from C++ and AWS to Node.js and Docker, leading end-to-end development for clients like the United Nations, Youtube and Mythos Labs. I focus on transforming complex challenges into efficient, user-centric systems, leveraging a strong R&D mindset to turn insights into high-impact products.
