That's definitely a good idea. I didn't think about that. Although it seems difficult to leverage my "disability" as a marketable asset - or at least how to frame it constructively.
In e.g. Austria regional or communal government, or agencies working with them, would gladly pick you up, give you a protected workplace and enlist you to help make all the e-government sites and processes more accessible.
I'm not simply claiming this. I used to work with a 100% blind developer, that had a degree from Uni Innsbruck in either Computer Science or Mathematics, I don't remember really. I could not understand how he managed to get a degree (in the 80ies or 90ies nonetheless), but even if he needed special tools, he was a very important asset in the whole e-government push, especially because he was apparently a very valuable software developer, albeit his challenges.
At the very least, you would need to run websites with an increased zoom which would give you an insight into what sites look like at non-standard sizes.
You'd also understand better than most the difficulty with but also how to improve tap targets or set better contrast, etc.
I think you can start just by making existing sites easier to use for yourself.
You can follow that up with learning how to improve sites for users with ever more difficulty seeing and then branch into hearing.
