Core Expertise

My primary comfort zone. These are the tools I use day-to-day and feel most natural with, representing my current mainstay technologies.

Deep Theory / Legacy

Technologies I worked with extensively in the past. While I don't use them as often now, they provided a strong foundation for how I think about systems today.

Active Learning

New tools and concepts I'm currently exploring or experimenting with. I'm learning by doing and finding where they fit into my daily workflow.

Entry Level / Exploring

Things I've briefly explored in the past or am just starting to look into. They aren't part of my current workflow, but I know my way around the basics.
