Principal AI &
Platform Engineer.
Principal engineer with 12 years building production AI and enterprise platforms. I ship MCP tooling, model routing, RAG, agent orchestration, and full-stack products across regulated environments, with measurable improvements to reliability and delivery. I am especially interested in aerospace and space infrastructure.
I build the system around the model.
I build the engineering that turns models into dependable products: typed MCP tools, retrieval, model routing, evaluation, guardrails, and multi-step agent workflows. The result is production software that can use real context, take bounded actions, recover from failure, and remain understandable to the people operating it.
Turn your APIs into agent tools
I generate and ship Model Context Protocol servers that expose existing systems as safe, typed tools, like the IMS MCP I built to bring AI tooling to parity with a core insurance platform's API surface.
The right model for each task
Multi-provider setups across Claude, OpenAI, Gemini, and local Ollama, with fallback chains and per-task selection tuned for cost, latency, and reliability instead of one model for everything.
Agents that plan, act & recover
Designing multi-step agent workflows: planning, tool calls, and orchestration, with the guardrails and observability that make them dependable in production. The thinking behind FleetRun.
Grounded answers, real context
Retrieval, vector memory, and document intelligence embedded where teams already work, from in-browser vector memory to NLP chatbots and Microsoft 365 document automation.
I build and run my own agentic infrastructure.
Eleven custom Model Context Protocol servers give my agents typed, governed access to the tools a real software business runs on. The models run on hardware I own and route per task, so cost and latency stay under control.

About.
Principal AI and platform engineer with 12 years designing, building, and scaling production software across insurance, healthcare, legal technology, and independent product companies.
My strongest work sits at the intersection of AI systems and product engineering: TypeScript and Python services, React interfaces, APIs, MCP tooling, retrieval, model routing, evaluation, and the operational controls that make agents reliable.
I am looking for Principal or Staff scope where I can own architecture and still build, with aerospace and space infrastructure as the priority. I bring regulated-industry discipline, founder-level ownership, and a long record of turning ambiguous problems into shipped systems.
