Academic, personal and shipped projects across cyber security, web, mobile and game development.
A local orchestrator that turns a request into a plan of role agents (developer, reviewer, tester…) working in isolated git worktrees, verifies their work with deterministic checks and only merges after my approval. Every agent is treated as an untrusted worker.
