I Make Sure Every Song Does What It’s Meant To Do

Before I touch a fader, I ask: What’s the purpose of this song?
To make people dance? Cry? Feel powerful? Smile in the car?

Every decision I make is tied to that purpose.

KC PORTER

"I’ve worked with some of the most talented engineers and producers in the business, but none have left as much of an impact on my music as Javier Valdeavellano (Javillano). His work ethic is unparalleled, and his engineering, mixing, and production skills are truly impeccable. He’s one of the few I would entrust my projects to wholeheartedly."

Producer, Songwriter & Arranger

(Michael Jackson, Santana, Ricky Martin, Selena, Bon Jovi, Celine Dion, Sting, Luis Miguel, Los Fabulosos Cadillacs)

Here’s How We Finish Your Song

It’s the final 10% that takes your song from “good” to unforgettable. Strategic choices, emotional depth, and a human ear that gets it. My approach is built to move people, not just meters.

STEP 1: Send Your Song + Align the Vision

You’ll fill out a quick form, send your multitracks, and we’ll make sure everything’s in place. I’ll confirm the files are ready and your goals are clear, so we start strong, with no surprises.

STEP 2: Get Your First Mix in 48 HRS + Unlimited Revisions

Once the files are approved, I’ll deliver your first mix and temp master within 2 business days. From there, we revise until it’s right — using guided tools or jumping on a live Zoom to nail it together.

After approval, I’ll bring in my trusted mastering engineer and deliver everything: mastered WAV, stems, instrumental, TV mix, acapella — fully labeled and ready to release.
