I was working on Nationbuilder, a horrible all-in-one master-of-none thing, back in 2016 or so, and ran so many concurrent tasks in our BE that it started affecting all of their other clients. Waking up an engineer in CA was fun
That thing is a pile of absolute dog shit. New up and coming UK political party are using it - I volunteered to help with setting up / maintaining their tech stack, realized within 5 minutes all their eggs were in that godforsaken basket and changed my mind.
