What I'm looking for

I'm looking for a QA, software testing, or requirements-focused role where I can apply my backend development experience, analytical approach, SQL validation skills, and focus on software quality.

At P&I Hellas, I've developed and maintained enterprise Java EE backend systems while ensuring quality through manual and regression testing across release cycles.

I've designed structured test scenarios, investigated and resolved defects with QA and development teams, and performed SQL-based validation to protect backend data integrity and business logic. I also work with Product Owners to clarify requirements and participate in Agile planning, reviews, retrospectives, code reviews, and Git-based workflows.

Previously at Evertz Microsystems, I supported customer platforms through scripting, JavaScript and XML configuration, database operations, Linux troubleshooting, and incident resolution. I'm transitioning toward a QA, software testing, or requirements-focused role where I can apply my technical background and analytical approach.
