Rusty Data is where my work lives: data pipelines, AI integrations, and data science applications designed to deliver measured value on real client assets.
Long-form write-ups of what I built, how it was measured, and what shipped.
I'm Zack Zofrea, a data scientist and machine learning engineer with 8+ years building models, ETL pipelines, and the production systems around them.
I build self-hosted and cloud platforms, AI-powered workflows, and the infrastructure to run them: on my own hardware when that is the cheaper answer, on a cloud platform when the workload needs it.
I pair program with my golden retriever, Oakley. She is my compliance officer and does an excellent job enforcing screen-time restrictions.
Integrate LLMs and agentic AI workflows where they actually save time and money.
Solutions are only as powerful as the data flowing into them. In the words of my first boss, "strapping a jet engine onto a lawn mower will just tear up your yard."
Language models will not solve all your needs. Purposeful machine learning models are the path to making data-driven decisions.
Self-hosted where it saves money, cloud where you need to scale. Containerized platforms keep control and running cost where you can see them.
