Important notice about the «ADG» project

Important notice: Due to large demand, the «Accessibility Developer Guide» project (currently a proof of concept with low priority) will become a top priority priority in 2017. We will make this guide become what it deserves to be for so long already: a comprehensive resource for all folks interested in accessibility. For this we need your support!

About the Accessibility Developer Guide

Portrait of Joshua

I'm working as a web developer (frontend and backend) since more than 10 years. My motto has always been: "Good code is clean code is less code is accessible code."

I'm working for «Access for all» for one year now, and being the first qualified web developer in the team, I'm heavily pushing our services for other web developers, be it creating this guide, holding workshops for developers or conducting in-house consulting for clients.

Portrait of Petra

I'm working as an accessibility consultant for «Access for all» since it was founded 15 years ago.

I suffer from hemiplegia since birth and I'm visually impaired as well. I control my computer using a standard keyboard with one hand a braille display. I'm using screenreaders and other assistive technologies on a daily basis and can offer a lot of experience in this area. As part of my job I do thorough website and mobile app testing including analysis of code.
