McDonald's ›Mein Burger‹

Technical stabilization and delivery improvement for McDonald’s Germany’s Mein Burger campaign. The starting point was a fragile high-load setup built around on-prem systems, Windows servers, Tomcat, and an insufficient proxy/cache layer. In a critical phase, I established a more resilient technical foundation and then moved the campaign onto a more robust and automated delivery model.

I first addressed the immediate load and stability issues by setting up a Linux-based system with a proper firewall and nginx as a fronting proxy/cache. This made the running campaign significantly more reliable. I then designed and built a standardized AWS deployment framework that could be integrated into Jenkins and automated production deployments across multiple stages and infrastructure scenarios. In its first live use for Mein Burger 2013, the platform ran without downtime even under very high load. This reduced manual effort, shortened the time to first deployment, and made campaign delivery much more robust overall.
