I’m a QA Automation Engineer with 5+ years of experience in Java-based test automation, focused on building reliable automation that reduces risk and speeds up feedback. I’ve worked as the sole automation engineer, owning end-to-end test strategy across multiple data processing platforms.

In my most recent role at Remote TechnoDiasoft LLC, I architected and delivered a test automation framework from scratch in 6 weeks using Java 17, REST Assured, JDBC, SSHJ, and JUnit 5. I applied Singleton, Builder, and Factory design patterns to ensure scalability while owning the full automation strategy across two internal data processing platforms simultaneously.

My core expertise is ETL pipeline validation across 5 database systems—PostgreSQL, Greenplum, Oracle, Hadoop, and ClickHouse—so data integrity is maintained throughout the entire pipeline. I also developed automated API and backend service testing with REST Assured and SSHJ, integrated into Jenkins CI/CD for continuous regression feedback on every deployment.

I strengthened regression coverage from 30% to 95% by systematically automating critical business scenarios, and reduced test suite execution time by 40% through parallel runs, optimized database queries, and selective regression scoping. I write more than 500 complex end-to-end tests, collaborate closely with manual QA and business analysts, and keep coverage aligned with priorities and documentation in Jira.
