Experience
I have more than 10 years of practical experience as a Data Scientist, AI expert, image analysis specialist and Python developer. I use AI methods pragmatically and can critically assess their benefits.
As a long-time leader of a data analysis service department in a scientific environment, I have gained experience in project management and personnel recruitment and actively participated in the development of new technologies.
As a Data Scientist in the field of wholesale and distribution, I know the requirements of medium-sized companies and can develop customized solutions in the field of AI, Big Data and Data Engineering with a sense of proportion for the respective budget framework.
Among others, I have worked on the following use cases:
- Prediction of sales figures (wholesale and retail)
- Processing and analysis of sensor data (biotechnology)
- Automated object recognition in medical image data (Biomedical Research).
- Data Science Consulting and Data Engineering and Big Data handling for the development of new therapies (drug discovery, pharma)
- Backend and frontend development of web based BI dashboards (investment banking).

Publications
Context-Enriched Data: The Secret Superpower for Your Deep Learning Model
In this post, I would like to share with you my approach to optimize input data for deep learning models. I have successfully applied it in my work as a data scientist and data engineer. On the basis of practical examples you will learn how to enrich model input data with contextual information.
How to Encode Periodic Time Features
Thoughtful processing of dates, days of the week and times of day for deep learning and other prediction models.
