I worked at a company making devices for blind and visually impaired users - screen magnifiers and OCR devices that scan whatever you put there and read it out to you. There are some very low hanging fruits in that domain. It was a very small family company, we had like 20 people total and just 2 developers, and none of us was blind, so we made some UI decisions that were very stupid in hindsight. Fortunately the company also has a distribution network for blind/visually impaired people stuff and we got feedback pretty quickly.

But I think that's one place where a blind developer would be more productive than average.

What I found surprising is the realization that computer hardware gets less accessible for blind people over time - touch screens are much worse than knobs and buttons, and graphical interfaces are much worse than text interfaces.

Web clients could help, but they also evolved from simple semantic DOM + some styling to dynamic js+virtual dom hybrid and "div-34gs34grtt" says nothing to the blind user.
