About Helmut

I translate business logic into clear, maintainable and verifiable data solutions that are designed with all end users in mind, not just those who commissioned them.

I work with small and medium-sized businesses, tax advisers, and non-profit organisations that require reliable, well-structured data, but do not need the overheads associated with a large consultancy.

Much of my work is workbook modelling. This means working with clients to design reliable data collection, organisation and analysis structures from the ground up. Some clients have a blank page and a problem to solve. Others have an existing workbook that no longer meets their needs. Rebuilding from scratch usually delivers better results than trying to fix what is already there. I say this honestly, even when it means more work upfront.

I help with:
-designing workbook models and data collection structures from scratch;
- restructuring chaotic or inherited workbooks into clean, logical architecture's;

-cleaning, validating and error-proofing datasets;
-automating reports and processes using Excel and Power Query;
-documenting everything so your team can maintain and adapt the solution;
-supporting tax advisers with client data preparation.

Good data work is like good plumbing: you don't notice it when it's working, but you do when it's not. I've seen it many times: a well-built solution that only its creator knew how to use. When they left, that knowledge left with them. Everything I deliver is documented, tested and built for the next person, so nobody has to call me to understand it.

    I'm an independent data consultant, and I specialise in workbook modelling, data structuring and process documentation for small and medium-sized businesses, tax advisers and non-profit organisations across Europe.
    Some of the more notable projects from the last 15 years include:
    I help private clients with their wealth management and financial modelling. I designed a structured Excel-based system for tracking investments, doing financial analysis and reporting, built to professional handover standards.
    This is a human resources data system for a construction company that specialises in commercial and public buildings. The full employee data architecture covers attendance, absences, payroll preparation, bad weather allowances, travel subsidies, regional public holidays across Italy and multi-level reporting with role-based access control separating payroll and HR management.
    The project management and quoting system is a long-term project that combines operational data to calculate and structure future project quotes more efficiently. This gives the client a measurable competitive advantage when tendering.
