10+ years across fintech, healthcare, and national security, most recently Principal Engineer at Capital One (shipped features for 3M+ daily users, delivered a revenue-generating product in two months with a skeleton crew). This past year I've been founding Spirit & Hammer, consulting & shipping AI products end-to-end: built the agent harness for a security startup, released Sun Signal (https://sunsignal.app) for circadian timing, and SkillGuard (https://skillguard.sh) to protect agent skills and harness environments from malicious injection.

I have a Mannan MCP server: https://mcp.mannanteam.workers.dev

Looking for senior/staff product or AI engineering roles. Full-time, part-time or contract.
