Who I Am

I'm Manakavoo Siva Balaji A — an aspiring AI & Backend Developer from Tirunelveli, India, with a B.Tech in Artificial Intelligence and Data Science from Francis Xavier Engineering College.

My work lives at the intersection of language models and real-world data — building RAG pipelines that retrieve and reason, FastAPI backends that scale, and intelligent systems that answer the right questions at the right time.

At Kadit Innovation, I shipped production RAG chatbots, LLM-powered analytics queries, and semantic search systems over live PostgreSQL data. I iterate fast, test hard, and build things that actually work.
