Hi, I am

Nihaarika Agarwal

MS Computer Science

I graduated from Computer Science MS at Arizona State University, specializing in AI. I’m passionate about using machine learning, NLP, generative AI and Agentic AI to solve real-world problems.

My experience includes research and development of RAG systems with VectorDB, prompt engineering, and RPA solutions that drive efficiency and impact. I enjoy building practical, trustworthy AI systems and constantly seek opportunities to learn, collaborate, and innovate.

Outside tech, I love reading and writing short poems. Let’s connect if you have an idea or challenge that could use a creative, analytical mind!
