Experience

Member of the Technical Staff San Francisco, CA · 2023 - Present

Early member of the Codex team, building cloud runtimes as the project evolved from internal retrieval and question answering into a cloud agent that produces mergeable pull requests
Experimented with incremental indexing for retrieval over codebases and built fast-starting container images for development against a large codebase.
On the Codex research team, restored multimodal capabilities to the post-training stack, enabling models to use visual feedback when evaluating frontend work and accept images and diagrams as input
Built the V8-based Code Mode runtime, enabling models to discover and compose tools while keeping unnecessary tool output out of their context. The approach improved token efficiency and made more agentic capabilities accessible to models with smaller context windows
Evaluated and hardened Code Mode’s security, moving the runtime from an embedded tool into an isolated, locked-down process
Led an engineering project to improve GPU reservation and allocation across teams, increasing utilization and enabling faster deployment of new models
Supported, operated and participated in on-call for our global GPU fleet serving large language models
