JUST THE FACTS: Age - 28; Hometown - Dayton, Ohio; Education - Studied mechanical engineering/computer science at the University of Vermont; Employ - Human, since Sept. 2004.

PREVIOUS EXPERIENCE: After graduating, Pacheco moved to Boston where he landed a job at Harvard in tech services. While there, he formed a band called Mus-ok ("a cross between Air and Beck") that's still together. After moving to New York and working as a PA on shoots, he got word of a gig in the dub room at Human.

WHAT HE LOVES MOST ABOUT THE JOB: "I've been learning the whole time I've been here."

BEST WORK: Sprite's "Liquid Freedom" for Ogilvy & Mather, Hong Kong. His effervescent indie-rock track accompanies b-ball players on a summer court that conveniently morphs into a pool. "I recorded the track in my apartment except for the drums," he says. "A friend of mine recorded those."

WHAT MAKES A GOOD SPOT COMPOSER: "Being able to interpret what the client wants and balancing that with what you think is cool." And being able to decipher client-speak - a popular directive Pacheco cites is "I want it electronic yet organic."

THE SONG HE WISHES HE WROTE: The Beatles' "A Day in the Life".
