Julia Undeutsch, Dev & UX Accessibility Specialist

I am Web & UX Accessibility Specialist at Atos Austria.

After graduating University in Musicology and Japanese Studies in summer 2020, I started learning front-end development and specialized in the topic of web accessibility early on. Since then, I take every opportunity to spread awareness on the topic by regularly creating content in form of writing blog articles and such.

Since 2022, I have been certified by IAAP as a Professional in Accessibility Core Competencies (CPACC). Since 2023 I am a Google Developer Expert for Web Technologies.

I’m a passionate technologist with 14 years of experience across mobile applications, embedded systems, custom hardware, backend development, and security modules. I build secure, scalable solutions through detailed analysis and practical problem-solving. I believe in continuous learning and enjoy collaborating with fellow developers to explore new technologies.

My expertise includes developing core libraries for custom hardware devices, embedded software, mobile applications, and security modules for various applications. I’ve worked on a wide range of projects, from mobile games to enterprise applications, IoT systems, and backend infrastructures, and I’ve tackled challenges at the OS library level, including custom mobile OS images.

I’m also experienced in Agile project management, version control systems, and CI/CD pipelines, ensuring efficient, iterative development. If you're interested in security, embedded systems, mobile platforms, or backend development—or just want to chat tech—I’d love to connect and exchange ideas!
