About me
Engineering digital products for the real world.
I am an experienced full-stack developer who turns complex operational requirements into dependable digital products.
Since 2010, I have worked at Notruf Niederösterreich across app and web development, IT support and network engineering. My focus is on systems that support real processes: dispatch environments, digital platforms, mobile applications and data-driven tools used every day.
I work across the complete product path—from interface and application logic to databases and infrastructure—always with clarity, maintainability and productive use in mind.
