About Vincent

Analytics Engineer with 10 years of experience spanning rigorous statistical research and hands-on data production work. PhD with a strong foundation in complex data analysis, Monte Carlo simulations, and uncertainty quantification (peer-reviewed publications).


Core expertise sits at the intersection of transformation layer engineering and business-facing analytics: designing Medallion architectures (Bronze/Silver/Gold), building dbt transformation pipelines, and turning raw multi-source datasets into reliable analytical outputs. Hands-on with the full data stack — orchestration (Airflown Nifi), processing (PySpark, SQL, Python), databases (PostgreSQL, PostGIS, Duckdb, Clickhouse ), and deployment (Docker, CI/CD).


Strong specialization in geospatial analytics (GeoPandas, QGIS, PostGIS, H3) and ML (XGBoost, scikit-learn, PyTorch), with applied experience on territorial and infrastructure datasets in international contexts.


Comfortable owning projects end-to-end — from data model design to production pipeline — and translating technical decisions into business-readable outputs for non-technical stakeholders.
