At Pryzmatech, I architected an AWS data platform that brought transactional event streams and product activity into Amazon Redshift for operational analytics and executive reporting.
I engineered modular dbt models and orchestrated ELT workflows with Amazon MWAA and S3. I also standardized cloud resources with Terraform and added automated data quality checks.
At Cognizant, I developed Python and SQL pipelines for AWS S3 and Redshift, and optimized PySpark transformations on Amazon EMR. I also built a RAG document assistant with LangChain and Pinecone for semantic search.
