I'm Jay. I'm a data scientist, and I live in Washington, DC area. I'm often doing work in data science, machine learning, data engineering, and web development. I mostly program in Python, though I occasionally use R. In a former life, I was an aerospace engineer and wrote a lot of MATLAB.
✨ Open Source Projects
Some of the open source projects I maintain include:
- cloudpathlib: pathlib-style classes for cloud storage services
- deon: a data science ethics checklist framework and tool
- erdantic: entity-relationship diagrams for Python data classes like Pydantic
- pkgnet: an R package for network analysis of R package dependencies and structure
- reprexlite: render reproducible examples of Python code for sharing
☀️ My Day Job
I'm a Principal Data Scientist and the Director of Engineering at DrivenData, where I do full-stack data science and data engineering consulting for social impact organizations.
🧩 Puzzle Hunts
I am also a puzzle hunt enthusiast and writer. You can find puzzles I've written as part of Advent Hunt 2024, Advent Hunt 2025, and MIT Mystery Hatch.
