Founder & Lead Developer
Shamshuddin created Percently with a singular focus: to build a better alternative to the cluttered, ad-heavy math utilities that dominate the web today. With a background in software engineering and a passion for clean design, he developed Percently to serve students, business professionals, and casual users who value speed and precision.
Why we built this
Most calculator websites today are cluttered with intrusive ads, slow to load, and designed with outdated interfaces from the early 2000s. We wanted to build something better—a tool that feels like a modern SaaS product, not a legacy utility. Percently is optimized for Core Web Vitals, ensuring it loads instantly on any device.
Precision and Expertise
Every calculator on this site is built with mathematically rigorous formulas and extensively tested for edge cases. We utilize modern web technologies to perform calculations in real-time within your browser, ensuring you get accurate answers without the delay of a page refresh.
Trust and Privacy
Transparency is at the heart of what we do. We don't require accounts, we don't track your identity, and we don't store your personal calculations on our servers. Your data remains on your device, always. This commitment to privacy is why thousands of users trust Percently for their daily calculations.
