Since August 2022, I've been working on a project called Aggregata, a blog where Henrik Bartsch and I write regularly about the web and AI.


In an effort to create a more streamlined structure for web projects, my colleagues and I designed and developed a revamped version of the agency's website.

Local Development Environments at neuwaerts

Together with my unit, we designed and documented modern local development environments and defined associated policies for contributors.

Staticbook at neuwaerts

Rising from the need to reduce the manual generation of documentation, I created a small internal tool to publish tailored documents in Markdown.
