"I turn uncertainty into security — with reliable systems and clear decisions."
/ about
Security through
reliable systems
I'm Leo — an Information Electronics Technician based in Munich, Germany. My mission is to make companies secure and capable of action, with reliable security systems and clean data infrastructure.
As a qualified Informationselektroniker at Elektro Kreutzpointner GmbH, I work daily with fire alarm systems, KNX building automation, and IT networks. Parallel to that, I founded Ritzenthaler IT — delivering IT network planning, VoIP, and IP camera solutions.
I'm also a developer: I shipped 3DFire, an AI-powered iOS app for planning smoke and heat detectors, and WattWissen, my apprenticeship graduation project built with Swift & Xcode.
I graduated as top of my class — skipping a full school year — and received multiple state-level awards for academic excellence. Currently pursuing my Meister qualification in Information Technology.
