Message

At Capgemini Technology Services India Limited, I developed an enterprise-grade GenAI chatbot using Python, FastAPI, GPT-5, and RAG to provide business insights. I also designed REST APIs, microservices, and LLM workflows for query processing.

I designed an AI architecture connecting Copilot/AI Agent, Microsoft Fabric Data Agent, and an ontology/semantic layer. I developed the AI query and data retrieval flow, and contributed to Azure deployment, monitoring, and production support.

Previously, at Thoughts2Binary Private Limited, I developed backend applications for a fleet management and telematics platform, including APIs for vehicle tracking and trip management. At GetWork and Authorly.Al, I contributed to backend services and APIs for a recruitment platform and an AI-powered content generation platform.
