Cyrus Sarkosh

Engineering lead for GEM (Guest Experience Management) from its first prototype, helping restaurants keep up with their ratings, reviews, and reputation across DoorDash, Google, and Yelp. Set its technical direction, grew the team, ran its design reviews, and set up its on-call and SLOs; built its real-time ratings pipeline, from webhook ingestion to async LLM analysis and automated replies guarded by evals, and the AI agents the team uses for QA and testing.
