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.
