Web Architect & SaaS Entrepreneur
Driven by the philosophy of "Logic without Jargon," Shivam Sagar started HQCalc with a simple goal: to remove the friction from financial planning. As a professional developer, he noticed that most online tools were either cluttered with ads or lacked technical precision.
With a background in building complex financial SaaS platforms, Shivam combined modern web technology with rigorous mathematical formulas to create a library that scales. Today, HQCalc serves as a growing repository of utilities designed to save time and increase accuracy for users worldwide.
