I've delivered quality assurance for critical banking, acquiring, and payment systems at Fiserv, including BankWorks, Fiserv Online, ControlM, CERC, and Argotechno.
I plan test strategies for features and releases, analyze requirements, model BDD scenarios, and validate end-to-end transactional flows through functional, integration, regression, exploratory, E2E, and UAT testing.
Across projects for Credit Suisse, Crefisa, Banco Original, Santander, First Data, and VIVO/Telefônica, I've tested web, mobile, financial, and telecommunications applications. I've also led test teams in Flutter and PIX Fraude squads.
I use REST API testing, Postman, SQL, SOA, Jira, Confluence, and quality-management tools to validate integrations, data, defects, and traceability. I'm continuing to strengthen my automation skills with Playwright, Cypress, Selenium WebDriver, RestAssured, Java, Python, and CI/CD.
