Starting with a new (ish?) machine, write down everything you need to do to get your development environment set up and building the code. Now, take a step back. How easy was this? It should ... must... be absolutely frustration free. If not, fix that. To come up to speed on the tech stack, go sit with the other developers. Get a feel for how they are using the technology. Then, start picking off some smaller issues from the backlog and try and fix those. Don't make assumptions. Learn the tech without an opinion. Sure, you won't like some of it (nobody likes everything), but find out if the team likes it. If they do, don't try to change that.
