Back to original languageAbout David
For me, Excel is not just a tool – but a tool to make processes truly better.
I support companies in transforming confusing workflows, Excel chaos, and manual steps into clear, efficient, and practical solutions.
Through my experience in the construction and project environment, I know what really matters in everyday life:
Time pressure, coordination, many stakeholders – and often a lack of structure. This is exactly where I come in.
My services:
- Development of individual Excel tools (e.g., for project planning, quotes, calculations)
- Creation of dashboards & analyses for clear decisions
- Automation of recurring tasks (VBA / formulas)
- Optimization of existing Excel files and processes
- Structuring of project and work processes
My focus:
I don't create complicated solutions, but tools that are actually used in everyday life – understandable, efficient, and sustainable.
Collaboration:
I am happy to take a look at existing files free of charge and identify optimization potential.
Collaboration on-site in NRW is also possible.
