Georg Pfeiffer
Teamlead Microsoft Development & Integration
I build system integrations and backend solutions in the Azure/.NET ecosystem. Based in Austria, working with public sector and enterprise clients since 2014.
I'm happiest when I'm connecting complex systems, simplifying architectures, and turning messy business requirements into clean, maintainable code. I lead a team that shares this obsession.
Career Journey
From a CS student in Vienna to leading integration teams building enterprise-scale systems. Every step taught me something about building software that actually works.
