Who I Am

I'm a Generative AI Engineer passionate about building intelligent solutions that blend research, real-world deployment, and innovation. My work spans Generative AI, Computer Vision, NLP, and end-to-end AI pipelines — from designing algorithms to deploying production-ready systems.

With experience across healthcare, manufacturing, and automotive domains, I've built real-time RAG pipelines, 3D reconstruction systems using NeRF & photogrammetry, document processing platforms on Azure AI, and AI-powered automation tools. I hold an M.Tech in AI from BITS Pilani and am a Kaggle Master (Competitions Expert top ~0.4%, Notebooks Master top ~1.3%).

I enjoy bridging the gap between deep research and applied business impact — with a strong focus on responsible, secure AI systems and governance.
