Siddarth Nandyala

Recognized by Andhra Pradesh CM N. Chandrababu Naidu as the world’s youngest AI‑certified professional (Oracle + ARM) while building Circadian AI — source: CM’s public X post (Mar 2025).

What they built

At age 14, Siddarth Nandyala built Circadian AI — a smartphone app that detects cardiovascular diseases in under 7 seconds with 96%+ accuracy by analyzing heart sounds using a cloud-based machine learning model. No additional hardware is required: users simply hold their phone to their chest. The app identifies arrhythmias, irregular heartbeats, early signs of heart failure, coronary artery disease, and heart valve abnormalities, and has been clinically tested on over 18,500 patients across the US and India. Earlier, at age 12, Siddarth founded STEM IT — an educational kit and workshop initiative teaching hands-on coding, robotics, and AI to students globally.
