Siddharth Nandyala is an Indian American teenager from Frisco, a fast-growing city in the Dallas–Fort Worth area of Texas, with roots in Anantapur in the Indian state of Andhra Pradesh. He belongs to a generation of young people who have grown up fluent in software and machine learning, and he channeled that fluency toward one of medicine's most consequential problems: the early detection of heart disease, which remains among the leading causes of death worldwide.
His flagship project, CircadiaV, reframes cardiac screening as a task an ordinary smartphone can perform. The app uses the phone's microphone to record the sounds of a beating heart, then applies artificial intelligence to analyze those recordings for patterns associated with cardiac ailments. According to reports, it can surface a potential problem in as little as seven seconds — a speed that could make preliminary screening feasible far from clinics and specialists.
The figures cited for CircadiaV are striking. Coverage from outlets including The Logical Indian and eHealth reported that the app had been tested on more than 15,000 patients in the United States and roughly 700 in India, with an accuracy above 96 percent. Those numbers, as reported, describe a tool that has moved well beyond a classroom demonstration toward real-world validation — the crucial threshold that separates a clever idea from a usable medical aid.
Nandyala's ambitions extend past a single app. He founded STEM IT TECH, a platform he uses to promote science, technology, engineering and mathematics education globally, positioning himself not only as an inventor but as an advocate for widening access to the tools he mastered so young. His recognitions have accumulated accordingly: an Innovator of the Year award from the Frisco Chamber of Commerce, acknowledgment associated with the U.S. House of Representatives, and public praise from Andhra Pradesh Chief Minister N. Chandrababu Naidu, who lauded the teenager's vision of extending healthcare to underserved regions.
Among the claims that drew the most attention is that Nandyala is the world's youngest AI-certified professional, holding certifications reported to be from Oracle and ARM — credentials that signal formal, industry-recognized competence in artificial intelligence at an age when most students have not begun to specialize. As with any superlative, the precise scope of the record is best treated as reported rather than absolute, but the underlying achievement — professional AI certification as a young teenager — is remarkable on its own terms.
What gives his story weight is the seriousness of its target. Building an accessible, low-cost path to cardiac screening speaks to a genuine global inequity: millions of people lack ready access to the specialists and equipment that catch heart disease early. A phone-based tool that can offer a rapid preliminary check, if validated and deployed responsibly, addresses exactly that gap. That ambition — practical, humane and technically demanding — is what elevates Nandyala above the many young people who simply build apps.
A measure of appropriate skepticism belongs in any account of a teenager's medical AI, and Nandyala's story invites the healthy questions that accompany all such claims: how the accuracy figures were measured, how the patient testing was structured, and what regulatory path any diagnostic tool must ultimately follow. Those questions are not marks against him but the normal scrutiny that separates a promising prototype from an approved clinical device — a road that even well-funded companies traverse slowly.
What is not in dispute is the shape of the problem he chose and the sophistication of his approach to it. Analyzing heart sounds — a discipline called phonocardiography — to detect murmurs and other abnormalities is a genuine, technically demanding application of machine learning, and framing it around a device nearly everyone already carries is exactly the kind of accessibility-first thinking that global health increasingly prizes. The ambition to reach patients far from cardiologists is both concrete and humane.
His parallel work as a founder and advocate rounds out the portrait. By launching STEM IT TECH and speaking publicly about widening access to technical education, Nandyala has positioned himself not merely as a young builder but as someone trying to lower the ladder for others — an instinct that, in a fourteen-year-old, is as notable as the code itself.
At fourteen, Siddharth Nandyala has produced a working medical-screening tool, founded an education platform, and earned recognition from officials on two continents. Whatever CircadiaV's ultimate clinical fate, he has already demonstrated the rarest combination in a young innovator: real technical skill aimed squarely at a problem that matters.

| Person | Country | Milestone | Age / Stat |
|---|---|---|---|
| Siddharth Nandyala | 🇺🇸 United States | CircadiaV heart-screening AI; youngest AI-certified professional | Age 14 |
| Lakshmi Agrawal | 🇺🇸 United States | ISEF 2025 Young Scientist Award for a pollution filter | Age 18 |
| Grace Sun | 🇺🇸 United States | ISEF top prize for bioelectronics | Age 16 |

Siddharth Nandyala matters because he aimed a teenager's technical skill at a genuine global problem — the early detection of heart disease — and built a working smartphone tool, CircadiaV, reported tested on tens of thousands of patients at high accuracy. That is the rare case of a young inventor moving beyond a demo toward real-world validation.
His broader profile — founding an education platform, earning recognition from officials in the United States and India, and being cited as the youngest AI-certified professional — marks him as one of the most consequential young innovators of his cohort, notable less for novelty than for the seriousness of the problem he chose.
