What I do

Systems designed to last. Not framework-of-the-month.

Independent audit of an existing system. Deliverable: a written report with prioritised risks and concrete refactor paths.

Fixed price: €1,800 (3 days)

Adopt AI coding agents without losing maintainability. Guardrails, structure, and a human hands-on - assisted coding, not vibe coding.

Systems that slowed to a crawl or stalled in delivery, diagnosed and unblocked. Search times cut by an order of magnitude.

Minimalism over opinion. Naming conventions over APIs. Maintenance is 95% of an app's life - every decision should serve that.
