I am Nitheesh Kumar Kaliraj, a B.Tech in Mechanical Engineering graduate from Anjalai Ammal Mahalingam Engineering College, class of 2025. During my studies, I completed internships and projects focused on backend development, REST API design, and Generative AI solutions, including building RAG pipelines, AI agents, and document Q&A systems using Python, LangChain, and the Google Gemini API. My strongest skills include Python, Flask API, REST API Design, Postman, Webhooks, and working with vector embeddings and ChromaDB. I am now seeking my first full-time role as a Backend Developer.
