Meet the Developer

Rana Muhammad Abdullah — Founder & Lead Engineer

As a Mechatronics Engineering student and a Full-Stack Web Developer with over 2 years of experience, I built LizoCalc to solve a simple problem: the internet is full of slow, ad-heavy calculators that are hard to use.

My engineering background ensures that every formula and mathematical logic used on this site is rigorously tested for accuracy. At LizoCalc, I combine my passion for precision engineering with modern web performance to bring you the best calculation tools on the web.
