HERE Technologies
01Software Engineer II
Building search evaluation platforms and the systems that explain how models perform.
- Refactored an automated ground-truth platform into modular comparison, clustering, and ML-pipeline components.
- Integrated LLM semantic similarity scoring and interactive HTML reports to classify outcomes and visualize query-level error distributions.
- Owned KPI drill-down across Search, Autosuggest, Autocomplete, and Geocoder — from Python report parsing and PostgreSQL storage to UI and Tableau views.
- Implemented AWS Lambda functions for on-demand KPI snapshot comparisons, with unit-tested pairwise comparison logic.
- Contributed to isolated Kubernetes benchmarks comparing deployed versions through Java Flight Recorder, CPU, heap, GC, and allocation insights.
