Exploring the Digital Cosmos

Generative AI Engineer based in Navi Mumbai, Maharashtra, India, currently pursuing my Bachelor of Computer Science at Pillai College of Arts, Science and Commerce with a CGPA of 8.5.

I specialize in building RAG systems and LLM-powered applications using LangChain, Groq, and Streamlit. Skilled in semantic retrieval, prompt optimization, and deploying scalable AI solutions with high accuracy and low latency.

During my internships at CodSoft and Unified Mentor, I developed AI-powered applications using LLM APIs, implemented RAG fundamentals including document chunking and embeddings, and built structured LLM workflows evaluated on latency and response accuracy.

I've deployed projects on Hugging Face Spaces with secure API integration, achieving approximately 95% accuracy and under 3 seconds response time in production AI applications.
