Sandesh Dhulekar is the founder of GlobalUtilityHub and the person behind all 61 tools on the site. He designs and codes each calculator himself, which means the guides he writes are grounded in the actual arithmetic rather than summarised from other articles.

His work covers personal finance (mortgages, compound interest, loan amortisation, tax brackets), health metrics (BMI, body fat, calorie needs), and developer utilities. Every figure published on the site is traced to a named primary source and stamped with the year it was issued, whether that is the WHO, the CDC, the IRS, or the Federal Reserve.

He is not a licensed financial advisor or medical professional. The tools and guides are educational, and every page carries a disclaimer saying so.
