> Mongo makes dev easy, but I worry about the long term cost when things get complex. I did a job recently and found that my brain struggled to keep the internal Mongo doc structure intact. I don't worry too much about that. You can use the repository patten to manage the serialisation and storage of your objects. Given this is something you'd typically do in most backends, I don't think it's a big ask. I do worry about the Mongo scare stories. > You can use Celery (uses RabbitMQ/Redis/Mongo/whatever underneath for the broker) for offloading the jobs in Python. Just add a decorator to your work function, makes it really easy (you can also use PiCloud if you need something with more crunching power) I can't remember evaluating Celery, so possibly I overlooked it. Perhaps it didn't work with Python 3 at the time? I'll have to look into Angular.
