Hello!
I am also a coder in the professional world with Ushers. I have Type 2A. I have found some employers don't answer back if vision loss is mentioned. I try not to mention in during the interview process, but I made sure to discuss it before accepting an offer. You will likely have to quit driving at some point with Ushers. You'll still be able to stay active, but you may decide that you don't want to wield 2 tons of steel when you could easily miss a cyclist or jaywalking pedestrian. Driving is something you have to prepare for exception not the rule. Long term, you will likely have to look in cities with good public transportation or a walkable commute to work.
Besides learning to manipulate screen readers at a rapid pace. One skill to practice is reading braille. When I was receiving assistive training at the Criss Cole Rehabilitation Center, I met MANY instructors who had personal experience coding without much vision at all. While they themselves chose to transition to a career helping others of all skill levels improve their access to computers, they reassured me that I would be able to be productive in a work environment with the right tools. The reason why I encourage learning braille is that in place of or paired with a screen reader, you could use a braille display connected to your computer. This allows you to employ more rapid mobility parsing a document than you might with a screen reader. I have not gotten fast enough at reading braille that I have justified the expensive purchase of a braille display nor has the need arrived currently, however, that is part of my long term plans for dealing with the situation.
