Holzmann
I am a software developer, researcher, and consultant based in Hannover, Germany. I hold a PhD in Computer Science and have worked internationally as a Web Data Engineer with the Internet Archive. My focus is on the effective and efficient use of web archives and related topics, including big data processing and information retrieval.
Consulting

As a freelancer, I offer consulting and engineering services in the following areas:
- Web Archiving
- Web / Big Data Engineering
- (Temporal) Data Processing
- Software / Web Development
Over the past years, I have worked internationally as a Web Data Engineer with the Internet Archive (archive.org) and Archive-It, leading organizations in the field of web archiving. As part of a non-profit team, I have contributed to maintaining and expanding one of the largest collections of freely accessible web data in the world.
Building on this experience, I develop innovative services and help derive new value from large-scale web archive datasets. I am also happy to support libraries and institutions interested in accessing and working with web archive data as an independent consultant based in Europe.
Previously, I earned my Master’s degree in Computer Science and worked as a researcher in Germany. My research focused on efficient access methods for web archives at the L3S Research Center in Hannover, Germany, where I completed and successfully defended my PhD in 2019.
If you are interested in working with me, please feel free to get in touch.
