Ryan Caldwellsenior software engineer

Work

I work on the inference platform that powers Copilot Chat.

Backend systems, platform and product APIs, model capabilities, and the infrastructure required to ship them.

Now

I led the implementation and product adoption of our platform's Responses API.

I help provide users with state-of-the-art LLM access, bring new model capabilities into AI products, and scale the platform that enables both.

Before

I built abuse protections for Copilot.

I worked on backend systems for Codespaces, insurance, and mobile device protection.
