About Frank

Hello!

For several years now, I have been intensively involved in developing and implementing effective solutions in Excel. True to the motto "If you can imagine it, there's a way," I have made it my mission to develop creative and efficient solutions for a wide variety of problems, including through the use of macros (VBA) and Power Query.

At my current employer, a renowned company in Düsseldorf, I have developed and successfully introduced tailor-made tools, analyses, dashboards, and prototypes in Excel. Many of these solutions have been in daily use for years and make a valuable contribution to increasing efficiency.

My services include, among others:

- Provision of business-specific reports and dashboards that are updated daily
- Automated processing and preparation of large amounts of data
- Development of algorithms for intelligent data linking
- Cleaning and optimization of master data (SAP, Oracle, etc.)
- Data preparation for migration
- Excel training for your team (often, food for thought is enough to solve problems internally)

A central goal of my work is that the developed tools are as intuitive and easy to operate as possible, without requiring significant manual effort.

I would be happy to support your company in optimizing processes and saving valuable resources such as time and costs!
