How I Build

I work with AI-assisted Spec-Driven Development: specification and architecture first, code second. I lead; AI executes under proven patterns (SOLID, Hexagonal Architecture, DDD). AI speed with scalable, maintainable code.

Architect — me

I define specs, bounded contexts, and design decisions. Architecture drives the code.

Engineer — Claude Code

Turns specs into technical design and drives the implementation, with SOLID review on every change.

Crew — OpenCode sub-agents

Run tasks in parallel — code, tests, and refactors — under the engineer's direction.
