Agentic Engineering

I designed repository-level AI workflows and reusable skills for architecture, planning, TDD, code review, PR follow-up, UI/mockup implementation, session handoffs, and multi-agent task delegation. The workflow emphasizes scoped ownership, explicit approval boundaries, deterministic verification, and human review rather than treating AI output as automatically correct.
