// ABOUT ME

Hi! I'm an Athens, Greece-based Sound Designer, SFX Artist and Post Production Sound Editor.
I earned my BSc in Music Technology and Acoustics Engineering from the Technological Educational Institute of Crete. I have worked in-house in an award-winning audio production studio for over three years, gaining valuable experience and delivering creative audio to production companies, agencies and well-known brands. I have also designed the sound of the Nintendo Switch console's game Skyland Rush: Air Raid Attack.
​As a full-time freelancer, I aim to provide exceptional audio services to independent artists, directors and videographers worldwide.
​Let's get to know each other and chat about your project.
