Nitin S.

I specialize in building AI-powered applications and autonomous agents that automate workflows, analyze data, and help businesses move faster using modern LLM technologies. Using tools like LangChain, OpenAI, Claude, Ollama, and FastAPI, I develop intelligent systems that can reason, retrieve knowledge, and perform real-world tasks. I help startups and companies build AI products, internal AI tools, and SaaS platforms powered by LLMs and automation.
