Mikael Miranda

I'm currently leading test planning, scenario design, and execution for Ília's Uphold system, with a focus on API testing, functional validation, and preventing defects before implementation.

I've built and maintained Cypress API automation suites to strengthen regression coverage and reliability. I also use Claude to identify test-suite gaps, generate and validate scenarios against business rules, analyze logs, and support scoped test automation.

At Engineering Brasil, I delivered quality assurance for Vale's GRM system across web and mobile platforms for approximately four years. My work included functional, exploratory, regression, and API testing; SQL data validation; defect investigation; and collaboration with developers and stakeholders to clarify requirements and expand coverage.

Across my QA career, I've applied BDD, CI/CD, and Shift Left practices while working with Cypress, Playwright, Postman, Jira, Qase, and Azure DevOps. I'm ISTQB CTFL certified and currently pursuing a postgraduate program in Software Quality Engineering and Software Testing.
