Building App Builder in M365 Copilot.
App Builder brings an intuitive, agentic experience to M365 Copilot with a rich set of tools to design and build personal and team productivity apps that are secure, governable, and sharable within the organization.
I led live app preview and playback for the Microsoft Ignite 2025 launch, coordinating multiple partner teams to deliver reliable in-product preview spanning the app container lifecycle, token-based auth, and Content Security Policy. I also architected independently upgradeable AI-generated apps through agent-controlled dependencies — turning a local fix into a cross-team architectural direction.
Focus
Designing and shipping the experience end-to-end, while prototyping the future of app creation: a provider-agnostic, service-hosted coding-agent runtime that runs agent harnesses in sandboxed containers, validated end-to-end with eval results comparable to the production agent.
