Executive Bio

I am an MBA-qualified Senior SEO Strategist and Revenue Tech Expert with over 13 years of experience in Revenue Operations at global giants like Novartis and Abbott. My relevance to a financial calculator tool isn't about being a CPA — it's about 13 years of real-world business financial management. The same skills that made me a top-performing sales executive at Novartis — meticulous accuracy with numbers, understanding how tax and revenue interact in business reporting, and my ability to explain complex financial concepts clearly — are exactly what inform this site's editorial standards.

"Managing territory sales budgets worth crores of rupees annually, I prepared quarterly revenue breakdowns for regional management, routinely working with finance teams on expense validation, invoice accuracy, and tax compliance documentation. This direct operational need — knowing precisely how much tax was embedded in a total to verify net revenue — is what inspired me to create ReverseSalesTaxCalc.org. I now oversee the accuracy of every rate table, review all published content, and maintain the rigorous editorial standard that makes this site a reliable financial reference."
