About Me
Hello, I'm Frank Zhao
Welcome to CalculatorVast! I'm Frank Zhao, a passionate developer and full-time maintainer of this platform, based in Xi'an, China - one of the world's most ancient and vibrant cities. As the sole founder and operator of CalculatorVast, I'm personally dedicated to creating the most reliable and comprehensive calculator platform available.
My Journey & Background
I graduated from Northeastern University with a degree in Marketing, which gave me valuable insights into understanding user needs and creating solutions that truly matter. However, my true passion has always been in IT and programming. Over the years, this passion grew into a mission: to create a platform where people can access accurate, reliable calculation tools without barriers.
That mission led to the creation of CalculatorVast. What started as a personal project has become my full-time commitment. Every single day, I'm working to expand this platform, improve existing calculators, and bring new tools to life.
