Projects & References
Here I summarize some of my most exciting projects and show which technology or technologies I used for them, which people I had the privilege of working with, and what the results were.
2025
Snowflake Datamart Development
This was a project I really enjoyed working on. It was also the first project in my career that I managed and was responsible for independently as a product owner. It took place in a diverse and international environment with a top contact person who acted as a link between many different departments and was very familiar with the customs.

Very happy to have worked with Marc. He is creative in finding sustainable solutions, concise in implementation and always has an “out-of-the-box” perspective.
Felix, project lead at Siemens Energy
The core of this project was to build a datamart to consolidate data from SAP, Excel, Oracle DB, and onePM (project management tool) into a central Snowflake instance, thereby providing the departments with data in a form suitable for analysis and reporting.
From a technical perspective, the core of this project was the interdependence of all assets (a ‘polymorphic construct’). My most important learning here was that even small adjustments can have a big impact—and that testing is essential. To limit the complexity, I created a mental lineage mind map that showed the connections between everything (view, table, task, Alteryx, Excel, etc.). This gave me a huge productivity boost.
The Tech Stack comprised:
Using all these tools to enable controlling and finance processes while ensuring 100% data quality was very challenging and helped me grow. I would like to take this opportunity to say a big thank you for the fantastic collaboration.
My Top 3 of this project:
1
Synergistic, harmonious, and agile collaboration
2
Implement top-down, from business requirements to technology
3
International and
diverse context
2025
Admin for internal servers and reporting
I was responsible for maintaining and developing the internal company network with various servers to ensure its functionality, and I was also heavily involved in ensuring internal reporting. In doing so, I was able to gain comprehensive knowledge of AWS, Twingate, APIs, Linux, SSH, and more.
The server network comprises an AWS-hosted VPC with several EC2 compute instances, most of which are Linux-based. This includes the internal wiki, which uses the open source software outline and is installed on Docker. For additional security and user authorization functionalities, the entire network is also protected by twingate Cloud.
By managing all these assets, I now feel very comfortable in the world of internal networks, know the best practices of security, and have the necessary background information.
2024
Factoring Dashbirds
This project was all about creativity and implementation skills. I am proud to have contributed to the internal reporting of this young company and to have built these aesthetic Dashbirds from scratch for the first time. Based on conceptual proposals, I created all these slides myself as an intern, working tirelessly through the night. That experience shaped me.
Side note: 40 KPIs spread across 6-8 pages. Below are actual pages with mock data.
A very important point in this context is hands-on balance — meaning: limiting your innate drive to work more effectively (not more efficiently). I had to learn this the hard way here.
I would like to thank the M-CO team, to whom I owe this experience.
My Top 3 of this project are:
1
Constant challenge due to high but realistic expectations
2
Personal development, enormous knowledge growth, and hands-on balance
3
Dynamic and highly personable team and top-notch mentoring
