Audio Engineer specialized in Sound Design, Editing, Audio Restoration, Field Recordings and Mix & Mastering for Audio Post Production.

About

My journey into sound started in 2008 in Lugo, Galicia, DJing at home. Later, together with some friends, we set up a collective and promoter company through which we organized electronic music events all across Galicia. Around 2014 I started getting into music production, learning to use sequencers like Ableton Live and experimenting with electronic music production hardware, until in 2015 I made the leap to Barcelona to study an undergraduate degree in audio production at SAE Institute, validated by Middlesex University.

It was during that degree where I truly discovered sound and where audio for film and television, commonly known as audio post production, became my passion. There I left behind DJing and music production to move into sound design, foley and 5.1 mixing.
After graduating, I joined Iyuno, where I spent five years working across all the technical departments in the studio like editing, recording, multimedia and quality control, but my best period came when I became a re-recording mixer, being the one responsible for shaping and giving sound to the Spanish version of series and films mixing in 5.1 cinema rooms.

After those five years, I focused on freelance work like sound design and mixing for media content, building my own personal brand and creating content, alongside building my own homestudio and personal portfolio to showcase my work in the field of audio post-production.

Portfolio

During my 5 years as an audio engineer at Iyuno, I worked on a lot of productions for the Spanish version, taking on roles across recording, editing, multimedia, quality control and ultimately as a Re-recording Mixer.
Here you'll find some of the most notable titles I worked on.

All demos have been produced in my home studio using Ableton Live and Pro Tools, combining sound design techniques and Foley recordings with tools like Krotos Studio, modular synthesizers, and field recordings captured with a Sennheiser MKE 600 boom microphone and a Zoom H4n Pro portable recorder to enhance the storytelling and create impactful sound design.

Services

Great visuals deserve great audio. If you're producing corporate videos, social media content, short films, trailers or ads, bad sound will silently cost you your audience's attention. Here's how I can help.

SOUND DESIGN
Do your videos fail to convey what you want to tell? Sound is 50% of the audiovisual experience, and a careless sound design breaks the immersion, drives your audience away and makes your content look amateur without you knowing exactly why.
If you need your videos to stand out through sonic storytelling, where every effect, texture and atmosphere reinforces your message and connects emotionally with your viewers, you are in the right place. I create personalised sound designs with meticulous attention to detail so your content sounds professional, retains your audience longer and stands out from the competition.

AUDIO BRANDING
Does your brand have a visual identity but no sonic identity? 80% of brands invest in logos, colors and typography, but when someone hears their content there is nothing that reminds them who they are.
Sound is the most powerful sense for generating emotional memory. A well-crafted sonic branding makes your audience recognize you before they even see your image, creates an unconscious connection with your values and turns every piece of content into a coherent and memorable brand experience.
If you want your audience to hear two notes and know it's you, you are in the right place. I create personalized sonic identities with precise creative direction so your brand sounds as good as it looks.

MIX & MASTERING
Does your content not sound professional and you don't know why? The problem might be in the mix, the mastering or even before that: in how you are recording.
I take care of mixing and mastering your videos, podcasts, interviews, ads and any audiovisual content so it sounds clean, powerful and consistent across all streaming platforms, with no volume issues, no annoying frequencies and no rejections for not meeting technical standards.
And if your recordings don't sound right from the source, I can help with that too: I restore problematic audio and help you record better, because a great mix starts with a great recording.
