I'm J.R. and I code mostly for fun. (No, really!)
I also code for work. My longest-running gig in the software industry was at Amazon Web Services between 2014 and 2023. I'm working on documenting my professional work here.
The following works are ordered roughly by the level of interest I've seen.
Projects with a + after the year are projects that I actively think about and work on. Projects without a + after the year are relatively stable; I may still make an occasional update, but I'm not thinking about them or planning more work for them.

I'm currently tracking down older games that I hope are lying around.
I have a list of games I'm trying to find here and am searching various machines and disks that I've got, but it will be a slow process. If anyone comes across something here, please let me know!
The following are solutions to various online coding challenges. Sometimes challenges get updated, so these may become out of date. They were working at the time of commit.
These are intended as a learning resource. Please don't cheat yourself out of learning. More sites and more languages to come.
