New York City Metropolitan Area
Backend engineer on Snap Map's team (400M+ MAU). I own the Go/Python ETL and geospatial systems that ingest, reconcile, and rank data from 10+ third-party providers (Google, Yext, TripAdvisor, Ticketmaster, SeatGeek).
What I've shipped:
• Architected the Places ETL in Go - the single source of truth for every place search, profile, and story served to 400M+ MAU.
• Recovered 4.1M corrupted place records (822K names, 1.1M categories, 3.9M geometries) after a provider-priority misconfiguration wiped curated attributes. Used BigQuery forensics + authored a reusable bulk-update script, now the team's standard playbook.
• Grew daily tracked POIs 80K → 200K+ (2.5x) and lifted total events on Snap Map 35% by building an end-to-end POI ETL in Go pulling real-time data from Ticketmaster, SeatGeek, and Gametime with geospatial matching + priority scoring.
• Shipped Smart POI Name Cleaning by integrating a 4B-parameter LLM (Qwen3-4B) into the POI pipeline via Snap's AGI Inference Service - auto-cleaning ~500 cluttered event titles per ingestion cycle.
• Drove a 29% lift in place-tagged Spotlight Snaps by designing the backend for "Spotlight Posting Hints" in the Send-To-Spotlight cell.
• Increased Ticketmaster POIs 3.5x and SeatGeek POIs 2x via concordance-based place matching - onboarded SeatGeek (~470K venues) and added Ticketmaster venue-ID lookups, hitting 89% POI-to-Place match.
• Owned pipeline observability: Grafana dashboards + alerting; authored the POI Improvement Roadmap (15+ proposals, 2 shipped as P0 same quarter); completed the HLS → STMS migration.
