What I'm looking for

I’m seeking a long-term opportunity in ETL testing and AWS cloud test engineering within an enterprise-level environment, where I can design test cases, validate data integrity, and deliver reliable results across QA/STAGE/PROD.

I’m an ETL/Data Test Engineer with 7+ years of experience in ETL testing, data validation, and verification across relational, cloud, and NoSQL databases. I design and execute end-to-end test scenarios across QA, STAGE, and PROD using Agile/STLC practices with Jira-based defect tracking and strong cross-functional collaboration.

In AWS cloud test engineering work, I build and run test cases covering SIT, UAT, NFT, E2E, and PROD environments—validating data pipelines from S3 to Athena and DynamoDB. I monitor AWS Step Functions failures via CloudWatch, retrigger jobs as needed, and implement SNS-based alerting; I also author complex Athena SQL to verify ETL integrity and validation logic.

I’ve also supported platform implementations (including Matillion) by leading phase-1 test readiness, performing dry runs on test environments, and presenting architecture overviews to stakeholders. Earlier, I monitored ETL pipelines and tuned long-running SQL queries, then prepared production patches ahead of release deadlines—always focused on data quality, audit-ready evidence, and reliable delivery.
