Background & Education

Engineering precise AI datasets, voice artistry, and human-in-the-loop validation.

I am currently in my final year pursuing a B.Tech in Artificial Intelligence and Machine Learning at Aditya University, Surampalem (Graduating Class of 2027).

My experience crosses the boundary between machine algorithms and real-world human judgment. Over the last two years, I have trained enterprise generative models through RLHF and SFT evaluations, annotated complex audio streams with high phonetic precision using Labelbox, recorded broadcast voice assets for US clients, and tested web and mobile systems for critical user friction.
