$ cat about.md

The developer who publishes his numbers.

I'm Thibault "Tibo" Denizet, a French developer living in Phuket, Thailand. I've been shipping software for thirteen years: two technical books, a decade of Ruby, three years at OmiseGO ending as Director of Engineering, and a consulting practice bringing in $19k a month.

Devmystify is where I teach the half of the job nobody taught you: turning the skills you already have into businesses. Consulting, products, SaaS, and the order to climb them.

The rule here is receipts. Every claim on this site has a number attached, the failures stay on the board next to the wins, and everything I build from here gets its revenue published, in public.

One email a week. Real numbers. If I would not act on it myself, I do not send it.
