Hi! 👋

I'm Jay. I'm a data scientist, and I currently live in Washington, DC. I primarily do machine learning and data analysis, with some web development and devops on the side. Nowadays, I mostly program in Python, though I also sometimes 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.
