Biography
I studied in San Francisco (USA), Jena (Germany) and Hamburg (Germany). During my studies, I realized the enormous potential of software and ICT to solve even the toughest of challenges. Since 2020, I became captivated by two questions. 1. How can software be applied to solve various sustainability issues? 2. How can one make software itself sustainable? The latter is especially interesting to me since I am myself a Software Developer. Therefore, I have become a founding member of the Green Software Manifesto (www.greenmanifesto.de) and I am researching and sharing ideas related to Green Software.

Developing and Deploying Software in a Sustainable Way
This is the second part from my interview with Ben Linders, which was published by InfoQ as articles. In this second part I provide an overview of best practices for the sustainability of APIs and I introduce a few tools, which a software development or operations team can use to measure or improve their softwares sustainability.

DevGreenOps: How to Design Sustainable Digital Services
Ben Linders interviewed me. The interview results were transformed into articles for InfoQ. This is the first article to be published. I introduce the concept of DevGreenOps (aka. DevSusOps) as an extension of DevOps that weaves environmental sustainability into every step of the DevOps cycle. I argue that minimalism, transparency, efficiency and awareness are useful pillars, when developing and thinking about sustainable software.

Changing The Climate - How Vienna Is Embracing Greenweb
Embracing GreenWeb practices is a profound challenge currently tackled by the WienIT, which is the digital backbone of the Vienna city utilities company (Wiener Stadtwerke-Gruppe). In this presentation we will show how WienIT is improving the sustainability impact of the digital services, which they develop and operate for their clients, like municipal utilities and transportation companies. We will show the approach, the challenges and the lessons learned, so that you can take these ideas and implement them in your own Web Projects.

DevGreenOps – ideas and inspiration for the sustainability of your DevOps Cycle
DevGreenOps is an approach, which takes inspiration form DevSecOps, GreenOps and agile development practices. It enables software developments to incorporate environmental sustainability into their projects and deliver solutions, which their users and planet will love. This session highlights concepts, research, tools and best-practices, which generate insights, inform decisions, help to take action, and ultimately allow you to create your own DevGreenOps-Cycle.

DevSusOps
integrate sustainability into every step of the DevOps-Cycle
DevSusOps is an approach, which takes inspiration form DevSecOps, GreenOps and agile development practices. It enables software development professionals to incorporate environmental sustainability into their projects and deliver solutions, which their users and planet will love. I will introduce the DevSusOps concept as well as tools and ideas, which will help you implement your own DevSusOps approach in your software projects. Among other things these ideas and tools will help you create transparency, generate insights, inform decisions, help to take action, and ultimately allow you to create your own DevSusOps cycle and approach.

Nachhaltigkeitsmeetings planen und umsetzen
Nachhaltigkeit braucht feste Termine
How do you create awareness and make environmental sustainability a non-functional requirement? How can one adjust and build upon agile development practices to enable teams, to factor in the environmental sustainability of their decisions. My article published in the IT-Spektrum magazine (edition 02/2023) helps to answer those questions.

Green Software
There has been extensive research in recent years about Green Software. In my talk, I introduced some of the key ideas and methods from this research and made the matter of Green Software more accessible. Furthermore, I introduced some areas in which in my opinion research is still lacking and provided a personal view on how this could be changed.

Software Development Project at Elite Graduate Program Software Engineering
How can software help with the green transformation
The Elite graduate Program Software Engineering is backed by the University of Augsburg, the Technical University of Munich and the Ludwig-Maximilians-Universität Munich (LMU). The students developed sustainability focused applications from the first idea to a working prototype. They were taught to consider not only the effects of using the software, but also the footprint of the software itself. Additionally, they were given the opportunity to learn more about sustainable leadership.
