Excel automation, Power Query & troubleshooting
I help businesses improve existing Excel workbooks and automate repetitive tasks. My focus is on Power Query, reliable data imports and troubleshooting workbooks with broken formulas, failed refreshes or slow calculations.
I start by tracing how data moves through the workbook and finding where things go wrong. From there, I can fix specific issues, simplify queries or automate the steps your team currently does by hand. I document the changes so your team can maintain the solution afterwards.
I bring 20 years of extensive hands-on experience with Excel. Both my university studies and my professional work have focused on management accounting (controlling), finance and IT. That combination helps me understand the business logic behind a workbook, check whether the results make sense and improve how those results are produced.
