AI engineer and solutions architect working across LLM integration, payment automation, mobile field apps and edge infrastructure. I pair spec-driven development with AI-orchestrated tooling (Claude Code, Cursor) to ship production software quickly — then verify every line, boundary and trade-off myself. Background in penetration testing and enterprise Google Workspace administration.
