About
As Head of Audio at Electric Castle — one of Europe's major music festivals — I lead a team of engineers, oversee technical infrastructure, and collaborate directly with national television broadcast teams to deliver seamless live and post-production audio across TV and digital formats.As a freelance music producer, I develop musical ideas, compose and arrange music, and shape harmonies, melodies, rhythms, tempos, and tone balances.
Beyond live and broadcast work, my background includes post-production for commercials, storytelling video, and branded media content, handling everything from dialogue editing and voice processing to mixing, mastering, and multi-format delivery. I work extensively with Logic Pro X, Reaper, Waves, and iZotope, and I actively research and implement AI-powered audio tools — including generation, processing, and editing solutions — to streamline and elevate production workflows.
