Message

At IPG Photonics, I designed and implemented an enterprise RAG platform on AWS for document search and AI-powered question answering, using Amazon Bedrock Knowledge Bases, OpenAI models, and vector databases.

I also built and deployed an agentic AI incident-investigation assistant with Amazon Bedrock AgentCore, LangGraph, and MCP. Its components support agent execution, tool integration, session memory, secure access, and CloudWatch observability.

At Mphasis, I architected secure AWS infrastructure with Terraform and CloudFormation, and designed document ingestion and RAG workflows. I also containerized applications for Amazon EKS and Fargate and supported cloud data-processing and streaming platforms.

Earlier, at HCL Technologies, I delivered AWS and .NET applications and automated infrastructure and deployments. At AdroitInfonexusPvt. Ltd, I supported application work across travel, healthcare, publishing, and automotive projects.
