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 (<a href="https://sunsignal.app" rel="nofollow">https://sunsignal.app) for circadian timing, and SkillGuard (<a href="https://skillguard.sh" rel="nofollow">https://skillguard.sh) to protect agent skills and harness environments from malicious injection.
I have a Mannan MCP server: <a href="https://mcp.mannanteam.workers.dev" rel="nofollow">https://mcp.mannanteam.workers.dev
Looking for senior/staff product or AI engineering roles. Full-time, part-time or contract.
