Who I Am

I'm a second-year B.Tech student in Artificial Intelligence & Data Science at Amrita Vishwa Vidyapeetham, Nagercoil (CGPA: 8.56).

I work at the intersection of clinical ML and survival analysis β€” building models that go beyond binary classification to directly model time-to-event outcomes in real patient data. I'm also an active open source contributor and enjoy building full-stack products.
