Amit Kumar Mahapatra

As a Senior Generative AI Engineer at Tata Consultancy Services, I design and build production-grade backend systems for complex LLM-driven applications, with a strong focus on LangChain-based orchestration, advanced RAG pipelines, and vector database architectures using Qdrant. My work involves developing scalable, multi-step agentic workflows leveraging LangGraph, integrating Azure OpenAI and transformer models, and implementing robust semantic retrieval systems for document intelligence use cases. I specialize in Python-centric backend engineering using FastAPI, Pydantic, and SQLAlchemy, enabling high-performance APIs, secure authentication (OAuth 2.0, Azure AD SSO), and distributed observability with OpenTelemetry. I have delivered end-to-end systems involving document parsing, embedding pipelines, state management, and human-in-the-loop validation, ensuring reliability, scalability, and low-latency performance in enterprise environments.

I hold a Bachelor of Technology from Silicon Institute of Technology, Bhubaneswar, with a strong academic foundation in Data Structures, Algorithms, Machine Learning, Deep Learning, and Natural Language Processing. My academic training emphasized analytical problem solving, mathematical rigor, and core AI principles, which I consistently apply in real-world system design and model-driven engineering. This foundation enables me to bridge theoretical concepts with practical implementations, particularly in areas such as semantic search, model evaluation, and optimization of AI pipelines, supporting the development of efficient and scalable generative AI solutions.

Applied problem-solver with domain experience in EHS&S conversational systems and classification pipelines, having prototyped chatbots that improve incident reporting through semantic search, clarifying question generation, and automated classification.
