Experience

My journey in web development began as a hobby when I was 14, building websites and fun applications for friends. After spending a decade working at sea as a marine engineer, I decided to follow my passion for technology and fully transition to frontend engineering—turning what I love into my profession. My professional experience spans a wide range of projects and teams, from large international enterprises to agile freelance environments. I have led migrations, built scalable architectures, and delivered high-impact features in fast-paced, collaborative settings. This diverse background has given me a holistic view of frontend development—from hands-on coding to cross-functional teamwork and technical leadership.
