Sidnei Junior
@sidneijunior
I’m a senior QA Automation professional building reliable test frameworks and CI/CD-ready automation for web, mobile, and desktop.
What I'm looking for
I’m a Quality Assurance professional with over 13 years of experience in test automation, focused on Selenium, MSTest, NUnit, and SQL. I blend technical precision with agile methodology to integrate automated tests into CI/CD pipelines and consistently improve product quality.
At WEX, I collaborate with cross-functional teams to ensure partner-facing software quality and stability across web, desktop, and mobile platforms. I develop and maintain automated test cases using C#, MSTest, Selenium, and Playwright, and I contribute to framework architecture and quality improvement processes.
I’ve driven end-to-end automation for complex debit card transaction flows—authorization, settlements, and edge case validation—by designing tests that simulate real transaction behavior, processing stages, response codes, and integration scenarios. I also use advanced SQL queries to support data-driven testing and apply test traceability in Azure DevOps through managed test plans and cases.
I’ve expanded automation beyond traditional UI testing by co-developing a custom Robot Framework and Python test framework (published via GitHub and Artifactory) and improving desktop testing with AutoIT and FlaUI. I even built a proof-of-concept AI-based failure analysis tool using Python and MongoDB to analyze test history and suggest likely bug resolutions, and I continue to raise quality standards by mentoring others.
