Mix & Go
Engineering that ships. Content developers trust.
I'm Cezar. I've spent 18 years building production software, and over a decade teaching developers through Mix & Go. Today I help companies in two ways.
Rails + AI consulting
Make sure your AI bets pay off.
Your team can build the feature. I make sure it doesn't break, misbehave, or run up a six-figure bill.
YouTube for devtools
Get found by developers who've never heard of you.
YouTube videos that show up when developers search for their problem, built by an engineer, with real code.
