staff engineer · spec driven development
The code writes itself.
The spec doesn't.
I build production systems with AI agents using Spec Driven Development. I built a complete crypto fintech — 13 apps, 70 days, solo.
25+ years shipping production software: INPE, Embraer, TUI Group (€23B, 20M+ customers). 30,000+ students trained. 400+ professionals in AI-augmented workflows.
The method comes before the tool.
Tools change. The way you build doesn't. Spec Driven Development turns intent into systems that hold up.
01 Specify
A vague intent becomes context, acceptance criteria, and an executable contract — before a line of code.
02 Build
AI agents execute against the spec with architecture and direction. The engineer reviews, not retypes.
03 Ship
Ship, operate, measure. The specification keeps regressions out as the system grows in production.
