What I'm looking for

I'm ready to apply my experience to build practical, high-impact AI solutions that drive innovation and business value.

At Amex Group, I design and deploy LLM solutions on SAP BW using prompt engineering, embeddings, and RAG. I integrated Claude and LLaMA for enterprise use cases including document summarization and intelligent search.

I also develop agentic AI workflows with Claude and Google ADK, connecting enterprise systems with APIs and memory management for multi-step task execution. My work includes FastAPI inference endpoints and serverless ML inference with Azure Functions.

Previously, I worked as a Data Scientist at Mindtree Consulting and a Data Engineer at Tata Consultancy Services. At Tata Consultancy Services, I developed an HCP content management system covering the AI model lifecycle and contributed to automation work that reduced resource allocation by 40% and increased production rate by 15%.
