Firstly, just offhand, the following stacks should be fully accessible with current tools: Node.js, Rust, Python, truly cross-platform C++, Java, Scala, Ruby, PHP, Haskell, and Erlang. If you use any of these, you can work completely from a terminal, access servers via SSH through Cygwin or Bash for Windows, and do editing via an SFTP client (WinSCP works reasonably, at least with NVDA). Notepad++ also makes a perfectly adequate editor, again with NVDA; I'm not sure about jaws if you're using that.
GitHub has a command line tool called hub that can be used to do some things, and is otherwise pretty accessible. Not perfect, but certainly usable enough that NVDA (one of the most popular screen readers) uses it now. Many other project management systems have command line tools as well. If you write alternatives to project management tools, you will have to convince your employer to use them. Replacing these makes you less employable. You need to work to make them accessible, perhaps by getting a job on an accessibility team.
The stacks you are locked out of--primarily anything Microsoft and anything iOS--can only be fixed with collaboration from the companies backing them. Writing a wrapper or alternative to msbuild that can let you do a UWP app without using the GUI is not feasible. I have looked into this. Doing this for Xcode is even worse, because Xcode is a complicated monster that doesn't bother to document anything--Microsoft doesn't document much, but at least gives you some.
I imagine this is not what you want to hear, but separating all the blind people into the corner and requiring custom tools for everything will just put us all out of work. if you're successful, none of the mainstream stuff that cares even a little right now will continue to do so, and you'll end up working on blind-person-only teams at blind-person-only companies.
