Bio:

I have been a software engineer for more than 10 years. In the last 7 years I have been working together with foryouandyourcustomers Vienna in supporting companies in b2b and b2c on their digitalisation journey of internal processes and online presence.
After completing two certifications (from Climatebase and One point five academy) on climate studies and corporate sustainability, I have been active in the climate tech as well. My work in the climate tech space focuses on providing consultancy and expertise for startups on how software solutions can be planned and support their teams into building their first MVP.

My passion topic and area of expertise lies currently in the touching points between software engineering, architecture and the environmental impact of software products.

Examples of previous talks / appearances:

Agile Meets Architecture 2025

This session with the title Applying refactoring techniques to improve environmental impact of a software application was focused on increasing awareness across the software architecture and development community on how we can integrate existing tools and mechanisms (such as refactoring) into our software development lifecycle and improve therefore the energy efficiency of any software.

Women & Code Meetup

The talk with the title Towards understanding and designing green software focuses on providing a basic understanding of principles of sustainable software engineering by Green Software Foundation and by giving practical examples how we can design the architecture of our software to measure and improve the carbon footprint of software.
