I build the bones behind the tools. If you’ve clicked on a calculator and watched numbers line up just right, that’s probably something I worked on. I care about accuracy, speed, and making sure every feature gives you something real. BirthdayCalculus.com is not about flashy tricks. It’s about quiet details that stick. I work alongside Margo, who brings the language. I focus on the logic underneath it. Together, we try to turn birthdays into something people can explore—not once a year, but whenever they feel like seeing their date in a new light.
