I will build advanced excel workbooks

I build complex, multi-sheet Excel systems that actually hold up engineering-grade logic applied to spreadsheets, from someone who's spent years managing cost estimation, process tracking, and documentation data in Excel for real manufacturing operations.

What I can build for you:

• Multi-sheet workbooks with linked cross-references (INDEX-MATCH, XLOOKUP, nested formulas)
• Cost estimation and BOM calculators
• Inventory, production, or quality tracking sheets
• Dynamic dashboards with charts and conditional formatting
• Data validation, drop-downs, and error-proofed input sheets (POKA-YOKE style I apply the same mistake-proofing thinking from my manufacturing background)
• Basic VBA macros for repetitive tasks

I don't just make a spreadsheet look good I make sure the logic is airtight, because in my day job a broken formula means a wrong cost quote or a missed defect. That same discipline goes into every workbook I deliver.
