Vadym studied system software engineering — a field that builds the habits of careful arithmetic, edge-case thinking, and double-checking sources. He brings that same discipline to consumer tools: every calculator on EasyCalc is built around one specific question, and every formula is checked against primary sources before it ships — published standards, peer-reviewed research, or official references, depending on the topic.
Each tool ships alongside a short article that explains what the result actually means, where the numbers come from, and what the limits are. The aim is a page that loads quickly, works on a phone, and stays honest about what a calculator can and cannot tell you.
If you spot a wrong formula, an unhandled edge case, or have a suggestion for a calculator that doesn’t yet exist on the site — get in touch via the Contact page.
