Daniel Volin · Data Engineer

I build across the whole data pipeline.

Data engineer working every stage — scraping, ingestion, cleaning, and analytics. This portfolio is where two of my passions meet: I point those skills at my own training, health, and travel data to show what I can build end to end.
