Rajat Kumar
With a strong technical foundation in computer science and software architecture (MCA), Rajat Kumar created HealthGrowth.in to solve a crucial problem in modern online wellness: inaccurate, ad-cluttered, and non-scientific online calculators.
Driven by a mission to provide 100% accurate, peer-reviewed health equations (calibrated against WHO, CDC, NIH, AHA, and KDIGO guidelines), Rajat engineered the platform's client-side calculation engine to deliver instantaneous results with zero privacy compromise. Based in Uttar Pradesh, India, he continuously maintains and expands the site's biostatistical algorithms and clinical content for the global community.
