About Me

AI/ML Engineer specializing in transforming advanced research into scalable, production-ready systems. I engineered a reinforcement learning framework that delivered a 65% reduction in EM simulation cost by optimizing antenna design with uncertainty-aware SAC agents and hybrid surrogate models.

My experience spans multilingual NLP pipelines, computer vision systems, large-scale RAG architectures, and secure communication platforms. I combine deep learning expertise with strong MLOps capabilitiesβ€”deploying models using FastAPI, Docker, Vertex AI, and optimized GPU workflows.

Based in Pithapuram, Andhra Pradesh, India, I focus on building AI solutions that are measurable, reliable, and impactful. My published research and applied engineering work reflect a commitment to creating real-world AI systems that solve complex technical and business challenges.
