About me
I am a QA Engineer and Data Engineer with hands-on experience in AWS-based data platforms, data validation, and test automation, and a solid foundation in DevOps engineering. I work on large-scale data modernization and migration projects in the banking sector, designing test strategies for complex ETL pipelines to ensure data quality and reliability in regulated environments.
My expertise includes Python-based test automation (PyTest, Selenium, AWS SDK), data and integration testing, and validating cloud pipelines using AWS services such as S3, Glue, Redshift, IAM, and CloudWatch. I also integrate automated tests into CI/CD pipelines and have hands-on experience with Docker, Kubernetes, GitHub Actions, Terraform, and GitOps workflows.
I’m interested in AWS, data platforms, cloud migrations, and DevOps-driven quality engineering.
