Who I Am

4.5+ Years of Experience
3M+ Global Users Served
10M+ Daily Users Impacted
90% AI Pilot Satisfaction

I'm a Senior AI Engineer and Full Stack Developer based in Hyderabad, specializing in Generative AI, LLM-powered systems, and cross-platform mobile development.

At WSAudiology, I architect RAG-based conversational AI assistants serving 3M+ global users across multiple hearing aid brands. My work spans the full AI stack — from LangChain pipelines and LangSmith evaluation frameworks to .NET MAUI cross-platform apps and Kotlin Android development.

Previously at Ixigo, I engineered features used by 10M+ daily users, including pioneering the Resume Booking feature from hackathon prototype to production scale.

I thrive at the intersection of cutting-edge AI research and real-world product impact.
