Distributed systems & APIs
Backend services scaled past 100K transactions per second, and a WHOIS API serving millions of daily requests with Redis caching. Set API governance standards across teams.

I build large-scale security platforms and high-throughput backends and I'm going deep on agentic AI — systems that take real actions through tools, not just chat. The twin on the right answers only from what I've actually shared and it says so plainly when it doesn't know.
Where I go deep, and what I build with.

4–6 engineering teamsCurrently going deep on AI that acts through tools, where distributed-systems thinking meets AI.
Focus areaOver 12 years across backend, security infrastructure, and platform engineering.
I'm a Staff Software Engineer based in Erie, Colorado, with over 12 years in software engineering. Most of my career has been distributed backend and security infrastructure — systems that process huge volumes of data reliably and cheaply. I'd rather solve a problem simply than over-engineer it. Right now I'm focused on agentic AI engineering: building AI that acts through tools, where distributed-systems thinking meets AI.
