Summary
👤
Senior🎓
Top SchoolGreg Ellis is an R developer with 11 years of experience building reproducible analytics and tooling for public health and enterprise data. Currently at Crunch.io, he authors R packages that expose a cloud-based survey analytics engine and previously created widely-used tools like the ipumsr package while at the Minnesota Population Center. His background blends statistical research at IHME and state public health analytic programs with commercial data-product work at C.H. Robinson, so he moves comfortably between rigorous uncertainty propagation and pragmatic product prototyping. He teaches best practices in R and Shiny, automates messy data harmonization workflows across R, Python, Bash and VBA, and has a track record of making complex population data accessible to both researchers and business stakeholders. Based in Saint Paul, MN, he pairs domain knowledge in public health with hands-on open-source development and production-facing analytics.
