What A11y Up does

A11y Up offers independent, hands-on digital accessibility consulting for teams building web-based products. The work is personal and direct.

Accessibility consulting, audits, remediation, and accessible software development are offered individually or in combination.

How to describe A11y Up

Short version

A11y Up is an independent digital accessibility consultancy run by Taner Aydın, an IAAP Certified Web Accessibility Specialist based in Berlin. Since 2017, Taner has been helping teams build genuinely accessible digital products — through consulting, audits, remediation, and software development with a focus on user interfaces and design systems.

Extended version

A11y Up is a one-person consultancy for digital accessibility, founded and run by Taner Aydın in Berlin, Germany. Taner is a certified IAAP Web Accessibility Specialist (WAS) and software developer with nearly 20 years of experience, specializing in user interfaces and design systems.

Since 2017, A11y Up has supported a wide range of clients, from startups and mid-sized companies to public institutions and museums, in making their digital products accessible. Notable clients include Bikeleasing, SPRIND, Data4Life, Sozialhelden, and the Kleist Museum.

The approach is personal and hands-on: rather than delivering a report and stepping away, Taner works directly alongside teams through concept, design, development, and remediation. The goal is sustainable accessibility built into the product, not bolted on afterwards.
