I have to admit, more and more I read about things on HN and just reason "ah this is tech beyond my grasp, and it makes sense to someone somewhere but not me". Lots of developer tools for languages I've not heard of or libraries that seem so remote and arcane I wonder who is using them.

Now in this case, it is solving a real problem, with a clear way to make money. Go Density Go.

Thank you. Fwiw, our eng team has deeply benefited from all those dev tools and libraries. The stack to result in real-time, accurate count is nuts. I think one of our devs, Gus, was on the thread. Maybe he can weigh in.

Right now our production backend relies on Postgres, Django, Kafka, Docker, Nomad, Celery (yes, those queues probably should be folded back into Kafka eventually), and lots of other open-source tech. I'm not sure if I should share much, and can't talk in depth anyway, about the embedded stack. And then there are the tools for developing the algorithm, and custom systems for assembly/test/pack in Syracuse.

Our web application is mostly TypeScript, React, RxJS.

The hardware is yours?

[guscost]

Yes, designed in-house by some very talented colleagues.

Nice job, that ain't easy.
