I have worked on various AWS services including S3, EC2, Lambda, Glue, and Redshift.

• S3 - Used for storing and retrieving data

• EC2 - Used for running virtual servers

• Lambda - Used for serverless computing

• Glue - Used for ETL (Extract, Transform, Load) processes

• Redshift - Used for data warehousing and analytics
