Ali Ahmed
Founder & editor, Ali Tools Express
Ali Ahmed is a freelance full-stack developer who builds websites and web applications for clients. He started Ali Tools Express to make the kind of calculator site he wanted to use himself: quick to load, free of clutter, honest about its limits and clear about its maths.
He writes and tests the tools on this site, checks each formula against the sources cited on the page, and maintains the guides. Finance, health, pregnancy and accounting content is published only after a qualified specialist has reviewed it; those reviewers are named on the pages they review.
