I build custom Excel tools that replace manual work: quoting and invoicing systems, dashboards, data cleanup and imports, and multi-file consolidation — 250+ projects delivered, from single-macro fixes to complete Excel-based business applications.

My tools are built for non-technical users and daily production use, and many clients keep me on long term to maintain and expand their systems.

What I Can Build

• Custom Excel VBA programs and workflow automation
• Automated data imports, validation, processing, and reporting
• Dashboards, KPIs, and point-and-click reporting tools
• Quoting, invoicing, budgeting, pricing, and billing systems
• Multi-file, multi-location, and multi-account consolidation tools
• Excel integrations with Outlook, Access, PowerPoint, databases, SharePoint, QuickBooks, and web-based APIs
• Improvements and repairs for existing Excel/VBA programs
• Automated PDF, email, Word, and PowerPoint document generation

My solutions are designed for real-world business use. They are intuitive enough for non-technical users, while remaining accurate, maintainable, and capable of handling complex or high-volume workflows.

I can assist with a one-time project or provide ongoing support as your processes and requirements evolve. Many of my clients continue working with me long term to maintain, expand, and improve their Excel automation systems.

Whether you need to automate a single task, modernize an existing workbook, or build a complete Excel-based business application, I can help turn your current process into a practical, production-ready solution.
