I've built an AI Doubt Solver, a production-grade full-stack RAG application with an Express.js REST API, Hugging Face embeddings, Pinecone retrieval, and Groq's Llama 3.3 API. I designed automated PDF chunking, embedding, retrieval, reranking, and grounded response-generation workflows.

As a Software Development Intern, I've developed a decentralized intelligent traffic management system using SUMO and TraCI to simulate real-time traffic flow and optimize signal control across multiple intersections. I also implemented federated learning with Flower and Rust-based communication modules to support privacy-preserving, scalable traffic-node collaboration.

I've also designed RockStream, a normalized music-streaming database system using SQL, indexing, views, constraints, and analytical queries. I enjoy building scalable, user-centric applications across Python, Java, React, Node.js, databases, machine learning, and Generative AI.
