ABOUT

Qwynn Marcelle

Founder, Marcelle Labs · Creator, SnapBack · Chattanooga, TN

I was an engineering lead at a Fortune 50 healthcare company and built software on the side that I actually need myself. SnapBack started after an AI coding tool cost me $12,000 in a single night. Marcelle Labs is how I ship production systems for clients who need it done right, not just done.
