I’m a senior Excel VBA developer with 29 years of corporate-level experience automating spreadsheet processes, enhancing productivity, and modernizing legacy applications. My clients have included MassMutual, The Hartford, Pratt & Whitney, Connecticut Children’s Medical Center, CVS/Health, and more than 85 Upwork clients. For Cornerstone Real Estate Advisers (a MassMutual subsidiary), I developed a suite of proprietary budgeting tools that saved the firm over $1 million in commercial software licensing fees. The suite of asset-type-customized workbooks ran successfully for two decades and was widely preferred to commercial software alternatives across a user base of 100+ property management companies in the U.S. and Canada. Excel VBA is my specialty. I build and code robust automation solutions, eliminate time-consuming manual tasks, and stabilize unstable or error-laden workbooks. I also integrate Excel with Word, Outlook, and other MS Office applications for data-driven document generation and communication workflows. With advanced writing skills and an editor’s keen eye, I deliver top-shelf documentation. I write clean VBA code that is easy to follow, maintain, and troubleshoot, using a style refined over nearly three decades—far more readable, efficient, and maintainable than typical auto-generated macro code. I'm experienced collaborating with professionals in finance, accounting, engineering, and actuarial science—delivering tools that streamline operations, enhance decision-making, and stand the test of time. I favor a structured, incremental development process—guided by clear communication and steady progress toward the right solution. My goal isn’t just to deliver working code—it’s to create lasting value, delivered clearly, with precision and purpose.
