I build Excel workbooks that engineering and operations teams can trust — protected formulas, validated inputs, VBA automation, and dashboards that update themselves.

Not formatted tables. These are calculation engines with named ranges, error handling, input wizards, and documentation. Built by a chemical engineer who has done this work in midstream oil and gas operations.

What I deliver: engineering calculators (process, pipeline, mechanical, safety), financial models, regulatory compliance tools, reporting workbooks with one-click PDF generation, and data processing macros that replace hours of manual work.

My track record: built 130+ engineering calculators across 13 disciplines, automated emissions calculations that cut facility reporting from 3 days to 5 minutes, and rebuilt a company's PSV/DEI reporting workbook with Peng-Robinson EOS calculations and VBA automation.

If your team is copying data between spreadsheets, running manual calculations, or waiting on consultants for routine reporting — I'll build a tool that handles it.
