VISHWAJEET RAJ SINGH

At CodeAlpha, I built and integrated REST APIs using Node.js, Express.js, and MongoDB, connecting React.js frontend and backend components. I also implemented authentication and database integration, and worked on debugging and testing.

I'm building SupportGPT AI, a customer support and business automation platform using LLMs and Retrieval-Augmented Generation. I implemented Qdrant vector search for company-specific knowledge documents and developed ticket summarization, intent detection, response generation, and knowledge-base question answering features.

I developed PawCare, an animal rescue platform with image-based reports, live location, and NGO coordination, reducing dispatch time by 40%. I also built Neighborly, a community assistance platform with location-based matching, and have solved 500+ DSA problems.
