I've built and maintained scalable test automation frameworks at Yum Connect - Tictuk using TypeScript and Playwright, covering web applications, REST APIs, and microservices.

At Amadeus, I automated UI, backend, web service, and API testing with Selenium, Playwright, Karate, and Robot Framework. I also defined test cases, plans, and strategies, signed off new features, and maintained regression sets through CI/CD.

My work spans Java, JavaScript/TypeScript, Python, Jenkins, GitHub Actions, Docker, Podman, Azure, and reporting with Allure, Newman, and Cucumber reports.

Earlier at Scotiabank Technology and Rappi, I supported test strategy, exploratory and regression testing, defect triage, incident management, SQL and PostgreSQL queries, and quality reporting. I'm a trilingual Electronic Engineer with ISTQB CTFL and Azure Fundamentals credentials.
