Built in layers. Owned end to end.
Every project starts with a real problem and the smallest stack that solves it. Products with real users run on Java, Spring Boot and PostgreSQL; small tools stay small, often one codebase with local storage. Specialist AI agents write, test and review the code under my direction, and I own the architecture and what ships.
Product thinking
Find real problems and useful solutions.
System architecture
Keep the stack simple and cohesive.
AI agent orchestration
Use specialist agents for implementation, testing and review.
Implementation & testing
Write, test, iterate, ship.
Ownership
Maintain and take responsibility for what ships.
