https://skymap.rulkens.com A browser based open source universe explorer. I'm in between jobs currently and finally took time to work on my passion project. It started with just visualizing some galaxy surveys, but it got a little out of hand and now includes everything from hi-res tiled earth/mars, Gaia star field (16M stars), a milky way renderer and much more.

It's so amazing to have the ability to gather and parse publicly available scientific data and actually visualize it in real-time. It's one of those projects I'm learning a lot from and can keep going with (the universe is a big place :)). As a software developer for 20+ years, its been mind-blowing and often also frustrating to have Claude generate code that I deem good enough. About half of my time has actually been spent on refactoring, building quite some skills in guiding LLMs in the process. I guess that part still hasn't changed in a growing codebase.
