Message

At HERE Technologies, I refactored an automated ground-truth platform for search model training and KPI calculation into modular components. I integrated LLM semantic similarity scoring and interactive HTML reports, and owned KPI drill-downs across Search, Autosuggest, Autocomplete, and Geocoder.

I also built LetzGo, a peer-to-peer carpooling platform serving 700+ users, with route matching, trip coordination, and payment workflows. On Popin, I launched iOS and Android apps alongside an API and organizer dashboard, and led two interns across onboarding, analytics, and UI testing.
