Hi, I'm Roger.
I've been writing software for money since 1991 and Ruby on Rails specifically since 2006 — before the 1.0 release. I've been CTO of two companies, lead architect on a national identity system used by millions of Dutch citizens, and the founding engineer of an AI image platform with users in 40+ countries. These days I run TTB Software as a one-person operation, on purpose.

Why I work this way.
Twenty years ago, a Rails app meant a team of 6 and a six-month runway. Today, with Rails 8 and AI as leverage, the same scope is one person in two weeks. Most agencies haven't internalised this. I have. So you get senior engineering, fixed price, code in your repo, no kabuki — and the margin is mine to give back to you.

It's a phone call. That's the worst it can get.
No discovery deck. No 45-minute "qualification" call. 30 minutes, your problem, my opinion. If we're a fit, you'll know by minute 12.
