Developer / Data Engineer
I did my first step on the path of object-oriented programming at school in 2008 using Java. I was fascinated by the endless possibilities of automation and information processing. During my MSc in Artificial Intelligence, however, in a mostly data-driven modeling environment, I was introduced to the Python programming environment and fell in love.
I ended up training a two-stream CNN for video analysis during my MSc thesis and published my results at the conference ICLR2020 in a paper: Analysis of Video Feature Learning in Two-Stream CNNs on the Example of Zebrafish Swim Bout Classification (Breier & Onken, 2020). All code is available in the corresponding GitHub repository.
I’ve started working at Unit8 in Zurich in January 2023 and will post about my experiences there soon.
What you can expect
When I work on a project, I do it with utmost conscientiousness and integrity.
Google Cloud Platform (GCP)
I am a certified Google Cloud Professional Architect since 2020. Considering that modern data pipelines need to integrate multiple data sources of significant sizes, a data engineer must understand the backbone of data processing in the cloud.
