Music producer and DJ with 10+ years shaping tracks, sound design, and sonic branding.
What I'm looking for
I’m a music producer and DJ with 10+ years of experience in music analysis, audio production, and live performance. My strength is turning deep listening into structured, energetic releases—grounded in music theory, rhythm, harmony, melody, and genre/subgenre classification.
I’ve built a catalog of 200+ original tracks and have worked as a ghost producer for major electronic music artists. I also perform at large-scale events, including Ultra Music Festival Mexico, EDC Mexico, The BPM Festival, and Destino Pacha Ibiza—bringing energy to audiences of 50,000+.
As Founder, Music Producer & Sonic Branding Specialist at Symphony (2024–Present), I create original music, audio logos, and sonic branding assets for brands and media projects. I lead creative work independently, delivering custom sound design and music for advertising, digital experiences, and audiovisual content with strict attention to quality and deadlines.
Before that, I managed Urbaned Radio as Radio Station Manager & A&R (2020–2023), curating programming and evaluating hundreds of tracks and demos for airplay and release opportunities. I identified emerging talent, applied critical listening to assess musical quality and audience appeal, and strengthened my talent evaluation approach through continuous pattern recognition and metadata/catalog organization.
