I work as an independent full-stack developer specializing in building innovative web applications: - Dive into Heritage (UNOSAT/UNESCO): I developed an immersive web platform allowing users to virtually explore ancient sites through a dynamic scroll-based interface. Each scroll action reveals new content - text, videos, or 3D objects - with seamless animations. - BarTunes: I single-handedly built a digital jukebox web application enabling users to play their music in bars. I managed the entire project from concept to launch, integrating Spotify, Stripe, and social media APIs. Key features: Interactive map for bar locations, user playlists, real-time queue system via Socket.io
