About

Professional summary

I am a Senior Software Engineer in Test with extensive experience across QA, test automation, and conformance testing in international environments. I have worked on desktop, web, mobile, and API testing initiatives, and I focus on building reliable automation solutions that improve product quality and delivery speed.

I specialize in test automation using C#, Playwright, JavaScript, Selenium, Appium, and SQL Server querying. I also work with tools such as Postman, JMeter, SoapUI, JIRA, Azure DevOps, Trello, Slack, MS Teams, Git, and Redmine to support testing, collaboration, and delivery workflows.

In my current role at Kaizen Gaming, I execute and maintain end-to-end and integration tests for casino providers across multiple markets. I also develop and refactor desktop and mobile web automation tests and use AI-assisted tools like Claude and Copilot to improve debugging, refactoring, test design, and productivity.

Previously, I coordinated conformance testing for the European Commission at Netcompany-Intrasoft, where I managed test planning, execution, deadlines, and stakeholder communication. I have also worked as a Senior Test Analyst and QA Engineer, contributing to test strategy, manual and automated testing, defect analysis, and quality assurance best practices.

My background includes experience in Greece, Ireland, the United States, and remote advisory work, which has helped me adapt to diverse teams and delivery models. I am comfortable collaborating with cross-functional stakeholders while also working independently to drive quality outcomes.

I am currently pursuing advanced studies in business and IT project management, and I hold multiple certifications in software testing, automation, project management, and IT service management. I continue to build on my technical and leadership skills to support high-quality software delivery.
