Hi, I'm Tamil Kumaran πŸ‘‹

AI Engineer | Generative AI | RAG | Computer Vision

I build practical AI systems across Generative AI, Retrieval-Augmented Generation, Computer Vision, and Machine Learning.

Currently exploring Agentic AI, MCP, Azure AI, and MLOps to build and deploy production-ready AI applications.


πŸ‘¨β€πŸ’» About Me

I’m an AI Engineer with an MSc in Artificial Intelligence from the University of Surrey and a B.Tech in Artificial Intelligence & Data Science.

My experience spans Computer Vision, Deep Learning, Natural Language Processing, and Generative AI. I’ve worked on image retrieval and segmentation systems as well as RAG applications using LLMs, embeddings, and vector databases.

I enjoy turning AI concepts into practical applications, from model development and experimentation to APIs, automation, containerization, and cloud deployment.
