Johannes fell in love with the piano at age 6. In high school he picked up the drums and the guitar. In 2000 he attended Berklee College of Music for production and engineering, where he graduated with honors. His first official gig was at "Blink Music" studio in Boston.

Relocated to LA in 2006, he co-founded rock band Shaimus as bass player and mixer, earning placements in video games, TV shows and the Sony/Screengems film "The Roommate". After Shaimus disbanded in 2012, Raassina began engineering and mixing full time and quickly established himself building relationships with artists, labels, and publishing companies.

His vocal engineering on Justin Bieber's "Purpose" (2015) awarded him a Grammy nomination for "Album of the Year". Johannes worked on two of the Billboard #1 singles, "Sorry" and "What Do You Mean". "Purpose" has been RIAA-certified 3X Platinum.

Johannes also engineered the entire soundtrack for FOX's re-imagining of “The Rocky Horror Picture Show: Let’s Do The Time Warp Again” (2016, produced by Cisco Adler). It features performances by Tim Curry, Laverne Cox, Adam Lambert, Christina Milian, Reeve Carney, Annaleigh Ashford, Victoria Justice, Ryan McCartan and others.

In February 2017, he collected his first iTunes #1 as a mixer with Toulouse's "No Running From Me", featured in the soundtrack of the film "Fifty Shades Darker" (Universal Pictures).
