About

One throughline,
many crafts.

Engineer, film enthusiast, competitor, and host. The common thread is building things people actually use.

Josiah Rininger

I’m Josiah, an Apple platform engineer who also makes films, runs short-term rentals, competes on stage and on the trail, and builds the occasional party game.

That sounds like a lot of unrelated things. To me it’s one habit: I find something I care about, learn how it really works, and then build or do the version I wish existed. That instinct started with code: shipping apps to the App Store before it was a job, and it never stayed in one lane.

It’s why I build SeeItEarly to get film fans to screenings early, why I run rentals guests rate five stars, and why I’ll spend months animating a short film just to say something the right way. The tools change; the approach doesn’t.

If any of that overlaps with what you’re working on, whether hiring, film, hosting, or something I haven’t tried yet, I’d love to hear about it.

Day job

By trade I’m an Apple platform engineer at a large entertainment company. The employment history is on the Software page. Opinions here are my own.
