Here be settings.

Yes, this is a fairly large box considering the low number of settings. One could even go so far as to say it could be more appropriately called "Page Setting".

Page Info

The decision to use just regular HTML, vanilla JS (mostly), and vanilla CSS to create this page was made as I didn't want to pick a specific framework.

I think sometimes developers get too attached to their framework of choice, and can get tunnel vision when trying to decide what to use for a new project.

Generally I'm framework agnostic as they all have their pros and cons.

A Little Bit About Me

Over the years I've gravitated toward companies where the work has a tangible upside for real people -- reducing food waste, helping conserve energy, improving access to healthcare. That's where I want to keep going.

On the technical side I work best as a generalist across the full stack, and mentorship is a big part of how I operate. Watching someone work through a hard problem and come out the other side is one of my favorite parts of the job.

I'm spending a lot of time thinking about AI too -- how to integrate it thoughtfully and where it actually adds value, rather than just adds complexity. The hype may be a bit overblown, but genuinely excited about what it can do when it's used well.
