Joshua
Hummell
Senior Analytics Engineer & Data Professional
I build the data systems that help organizations understand themselves — clean pipelines, rigorous models, and infrastructure that lasts. My work sits at the intersection of analytics engineering, data infrastructure, and the craft of making complex data legible.
With a background spanning dbt, BigQuery, Python, PySpark, and Databricks, I've worked across marketing analytics, enterprise orchestration, and hands-on data modeling at companies including Navy Federal Credit Union, Samsung, Digitas, and Terakeet. I hold a Master's in Data Science.
Outside of work, I write, photograph, and build side projects at the edge of data and software. I'm an OCI cardholder with deep roots in Bangalore, and a father to a very young reader.
