About

Hi, I’m Guillermo Sumalla, a 22-year-old audio-visual professional focused on sound technology. I have worked for RTVE, Spain’s largest television company, where I ensured clear audio capture and delivery, managed mixing consoles for live and recorded programs, and coordinated with artists and guests to create a high-quality final product. I’ve also assembled and dismantled equipment and contributed to project planning and on-site operations to keep productions running smoothly.

Beyond broadcast work, I freelance in the music industry, handling pre-production, recording, mixing, and mastering. I’m proficient with DAWs such as Pro Tools, Reaper, and FL Studio, and I bring hands-on experience with microphone setup, sound design, and post-production plugins to deliver professional sound across diverse projects. I’d welcome the opportunity to continue developing my skills within your company and contribute to great audio-visual work with colleagues and artists alike.
