I'm Felix Grad from Dithmarschen in northern Germany, known online as FelixTheDev. I build websites, web and Android apps and automations for clients worldwide, and I take care of domains, servers and hosting too. Everything about my work, my projects and how to reach me is on felixthedev.com.
At my day job I'm training as an IT specialist for system integration at a municipal administration and build tools my colleagues use every day, which is why they have to work without a manual. Three things matter to me. Load nothing from third-party servers. Store personal data encrypted or not at all. Build interfaces that hold up on a phone. On the side I make games on Roblox.

How this page is built
None of the graphics above come from a third-party service. A small script in this repository (scripts/build.js) fetches the numbers from the GitHub API once a day, works out streaks and weekdays, and draws the SVG files in assets/. No dependencies, no trackers. Visiting this page loads nothing from anywhere else.
The animations live inside the SVG files (SMIL), so they run without JavaScript. Texts, skills and links are in profile.json, the colours in scripts/theme.js. The brand logos come from Simple Icons (CC0) and are copied into scripts/icons.js. To reuse it for your own profile: fork, edit profile.json, add a token with read:user as the secret PROFILE_TOKEN, done.
