Konda Balaji Rao

AI & Machine Learning Engineer


About Me

I'm an AI & ML Engineer focused on building production-ready systems — from multi-agent RAG pipelines and computer vision models to scalable backend architectures. I specialize in turning complex ML research into reliable, deployable solutions using Python, TensorFlow, PyTorch, and AWS.

Currently completing my final year of B.Tech (CSE-AIML) at Vignan's Foundation for Science, Technology and Research.
