Building the agent infrastructure, evaluation platforms, and streaming systems behind production AI features at scale.

About

Backend and infrastructure engineer who turns ambiguous, fast-shifting product areas into production-grade platforms other teams build on. In seven years at Slack I shipped the company's first production LLM response-streaming, built the multi-turn agent infrastructure behind its production AI assistant, and re-architected the quality and evaluation data platform behind every Slack AI feature. Before AI, I spent years building and scaling Slack's messaging and notifications backbone. For the specific systems I've built and shipped, see Experience.

What motivates me most is the end product — building something people genuinely love using. That's why I care so much about the unglamorous foundations underneath it: the frameworks, serving paths, and evaluation tooling that let other engineers move fast and ship AI experiences worth loving. I'm focused on building large-scale AI infrastructure in service of that.
