At Cognizant, I build and optimize batch and streaming data pipelines, ETL/ELT frameworks, and Data Lake, Warehouse, and Lakehouse platforms across AWS and Azure. I've improved Spark and Redshift performance, automated infrastructure with Terraform and CloudFormation, and delivered reporting solutions using Power BI and Tableau.
I've also built enterprise AI-powered data product agents using LangChain, LangGraph, CrewAI, OpenAI, Claude, AWS Bedrock, RAG, MCP, vector databases, and FastAPI. I collaborate across business, product, DevOps, and security teams while contributing to architecture reviews, code reviews, mentoring, and production-ready cloud solutions.
