Sven Hermann
I work as an independent software developer and IT consultant for companies and startups — and teach IT topics in German and English.
From idea to production — and beyond.

Independent since 2003 — by conviction.
I build software, advise teams and teach IT — for more than twenty-five years, from Berlin, for companies and startups.
It all started on a C128: first BASIC, then assembler — and the fascination with computers and everything around them has never let go of me. I have been working as a software developer since 2000, independently since 2003.
My focus is on web technologies across the entire stack: from the interface to the API to the cloud infrastructure. I like solutions that last — and code the next team will still enjoy reading.
In my spare time I tinker with microcontrollers and hardware — Arduino, ESP8266/ESP32, sensors, MQTT. As co-founder of 1less GmbH, that turned into a business: an IoT-based reusable tableware system with RFID technology and sensors, built to cut down on single-use plastic waste.
And since 2016 I have been teaching IT topics — courses, workshops and training, in German and English. The AI literacy training under Art. 4 EU AI Act has a site of its own: svenhermann.de.
