4+ YoE, ML Engineer with expertise in GenAI, HybridRAGs, LLMs & Agents
IndiaI am a passionate Data Scientist currently working at IBM, where I contribute to the development of modular, enterprise-grade Hybrid RAG systems tailored for the financial domain. My work involves leveraging advanced technologies such as vector search and knowledge graphs to enhance the accuracy and reliability of our solutions. I take pride in building and maintaining ingestion and preprocessing pipelines for multi-layout, semi-structured documents, optimizing for chunking efficiency and retrieval relevance.
Previously, I served as a Lead Backend Engineer at Tata Consultancy Services, where I led a team to create an internal GenAI chatbot that significantly improved technical query responses for over 40 developer teams. My experience includes designing scalable APIs and implementing intelligent caching mechanisms that drastically reduced query latency. I am also actively involved in innovative projects like Woodle.ai and RiotJet.com, which showcase my ability to blend AI with practical applications.
