I have worked for six years as a software and DevOps engineer at OTTO Group IT, where I designed and developed multiple cloud-native applications and contributed to the company's internal AI chat platform. In recent years, I have increasingly engaged in various open-source and freelance projects, particularly within the Nextcloud ecosystem, where I maintain several popular open-source projects.
I am fluent in both English and German, with German being my mother tongue. If you believe I could be a good fit for your project, I invite you to to contact me.
I am particularly interested in projects that drive positive change and make a meaningful impact in our communities, such as those that foster civil rights, democratic participation, diversity, accessibility, and education. If your project aligns with these values, I would love to discuss it further!
I've been building software with lots of programming languages, frameworks and tools and I'm always excited about learning new technology.
I believe in finding the right tool for the job, but of course there are some languages that I particularly enjoy working with, like Rust, go or Kotlin.
Infrastructure as Code, integration tests and strong monitoring/alerting: Automation paves the way to fearless and disruption free releases.
In my time at OTTO group IT (later one.o) I have often supported teams as CI/CD expert (apart from building automation for my own products).
From serverless cloud applications, over kubernetes clusters to traditional services on plain linux servers, I have many years of experience in running services in a cost and maintenance efficient way.
I see it this way: The less time I require to keep existing services running, the more time I can spend on writing new software. :)
Nextcloud Atomic is an easy-to-use, batteries-included system for running Nextcloud, that's optimized for robustness and security.
It features a custom admin interface written in Rust and Dioxus which provides everything needed for administration tasks while maintaining a minimal attack surface thanks to the kernel's sandboxing and isolation features as well as the excellent systemd stack (used for service management, updates, trusted boot, etc.).

At ottogroup one.o (formerly OTTO Group IT) I was part of the team which builds ogGPT, the company's internal AI chat platform. It allows ~41 000 employees to safely use the latest AI chat technology while respecting compliance and remaining vendor independent.
One notable feature I designed for ogGPT was end-to-end encrypted storage of user chats with cross-device key synchronization.

For many years, all SAP systems managed by the ottogroup one.o (formerly OTTO Group IT) had been operated by a service partner in a traditional data center. In 2021, however, we set out with a small team to take charge of operations and run all of those servers with our own staff in virtual machines in the Google Cloud Platform. Within this project I was focusing on cloud and security architecture, supporting the team as GCP specialist and devops/automation engineer.
