About Me
Hi there, I'm Sonal.
I am a full stack developer | AI engineer with a strong interest in building intelligent, scalable products that feel elegant in use and dependable underneath. My work usually lives at the intersection of modern frontend systems, backend architecture, and applied AI.
I enjoy taking ideas from rough problem statements to shipped experiences, whether that means designing APIs, structuring data flows, or integrating LLM and retrieval workflows in a way that actually helps users.
