Consulting
You have research data but no infrastructure to analyze it at scale. I build it.
I work with research institutions, startups, and policy organizations on problems at the intersection of data engineering, geospatial analysis, and empirical research design. My experience at Oak Ridge National Laboratory and NYC government gives me a practical understanding of both production infrastructure and rigorous methodology.
Services
Data Pipeline Engineering
ETL/ELT design, Airflow orchestration, schema harmonization across heterogeneous sources, columnar storage migration (Parquet/zstd), and metadata management. Experience processing multi-terabyte multi-source research datasets.
Geospatial Data Integration
Multi-source geospatial feature matching (fuzzy + spatial proximity algorithms), OSM data wrangling, GeoParquet pipeline design, spatial quality assurance frameworks. Uncommon expertise that sits at the gap between GIS and data engineering.
Research Infrastructure Design
Docker-based reproducible environments, data governance frameworks, DUA-compliant data management, versioned metadata schemas, and cross-institutional data sharing infrastructure.
Causal Analysis & Research Design Support
Difference-in-Differences study design, matched control construction, time-series cross-validation, SHAP/ML interpretability, equity stratification. Applicable to policy evaluation, public health research, urban systems, and infrastructure resilience.
Selected Project Experience
