## Headline

Senior Software Engineer at Runable \| AI Engineer building AI agents and LLM applications \| Agent Infrastructure, Sandboxing, Computer Use \| TypeScript, Go, Python

## About

I build AI agents end to end, from the product people use to the infrastructure the agents run on\. At Runable, an AI agent platform with 2M\+ users in 218 countries, I own the sandbox infrastructure behind 20k agent chats and 660k tool calls a day\. I led its move to a cheaper microVM provider, modeled at 8\.3x lower cost with writes about 12x faster, and built the vendor\-agnostic layer that lets us swap vendors on live traffic\. I also unified the agent runtime so one agent runs in a cloud sandbox or on a user's Mac through a single tool registry\. I like building products from zero\. On my own I built a computer\-use agent that drives a browser and desktop, Runable Flow \(a native macOS dictation app, built in 3 to 4 days\) and a proactive suggestion engine that ranks what needs a user's attention across every app they connect\. On the LLM side I run model evals, engineer context and tool calling, and route model traffic through a server\-side gateway\. An 8\-model eval I ran for dictation cleanup took the graded pass rate from 180 of 219 to 219 of 219\. Before Runable I was a Senior Software Engineer at Pixxel, where I built the order desk for hyperspectral satellite imagery, Go backend services, and an adapter architecture that made LLM features pluggable and cut development time 55%\. At SixSense I made an AI defect analytics product 4x faster, which helped win major clients and lifted conversion 35%\. I work in TypeScript, Go, Python, Rust and Swift, on Linux, microVMs, Docker, Kubernetes, Google Cloud and Cloudflare Workers\.
