What I'm looking for

I’m looking for a junior data engineering role where I can build reliable ETL pipelines, strengthen data modeling (e.g., star schema/medallion), and work with clear monitoring, testing, and documentation to ship analytics-ready data.

I’m a junior data engineer who delivers end-to-end data engineering solutions, from ETL pipeline development to data modeling, so teams can trust analytics-ready data workflows. I’ve leveraged tools like ApacheAirflow, dbt, Azure Data Factory, PostgreSQL, and Power BI to keep pipelines consistent and monitoring-driven.

In my most recent role, I built and tested an ApacheAirflow ETL pipeline for educational datasets, improving data accuracy by 20% through enhanced validation logic. I also designed a star-schema data warehouse that improved query performance by 50% in load time, and implemented automation with ApacheAirflow DAGs that reduced job failures by 25% using alerting and retries.

I also bring strong documentation and architecture thinking—creating end-to-end architecture diagrams and workflow docs that reduced onboarding time by about 30%. Previously, I worked as a QualityAssurance Tester, where I designed test cases, executed API testing with Postman, and used JIRA to track defects—experience that directly strengthens how I validate data quality and drive reliable outcomes.
