You'll be seeing sounds! Certified Mixing and Mastering Engineer ready to bring your project to life!
I've been doing my own vocals tuning in Melodyne Assistant, manually note by note, for my YouTube covers and my authorial songs since 2020, every week. Now I decided to offer this service for who need a natural and careful vocal tuning for their songs.
I have been a guitarist and composer for 20 years and have performed with notable indie and country acts in Nashville and on the road. I have experience in both session work, composition, tracking, & mixing as I've learned from artists and writers such as Kacey Musgraves, Little Big Town, Daniel Tashian, Aaron Marsh (Copeland), & Tomo Fujita.
I produce professional, radio-ready tracks across multiple genres — from hip-hop and R&B to pop, and much more — helping artists bring their sound to life with creativity and precision.
