The Developer Behind This Site 
Hola! I'm Niraj Kumar, the passionate front-end developer behind Calculator Online. With a background in web development, I've always been fascinated by the power of Internet that have impacted the mankind.
I believe Internet is one of the best invention done by homo sapiens. That's why I dedicated myself to developing apps and websites that address real life problems and provide value to people's life.
I started this project as a side project with only one goal in mind - to provide modern yet easy to use calculators. But with the passage of time, this website attracted thousands of users, and as of today hundreds of people use Calculator Online everyday to carry out simple as well as complex calculations.
I am interested in a lot of different areas of life. When I'm not coding or designing new tools, you can find me playing a Kalimba or making illustrations.
I also like to solve puzzles and develop web games in my free time.
Thank you for visiting Calculator Online, and we will keep bringing new and niche based calculators to our website.
