Sérgio Reis
@smcostareis
Senior Test Engineer specializing in automation, CI/CD integration, and scalable QA frameworks.
What I'm looking for
I am a Senior Test Engineer with extensive experience building and maintaining automation frameworks (Playwright, Cypress, TestCafe) and integrating testing into CI/CD pipelines to enable reliable, frequent releases. I have led QA efforts across frontend and backend systems, designed test strategies for complex domains, and delivered measurable improvements in coverage, stability, and release cadence.
I collaborate closely with product and engineering teams to define acceptance criteria, review code, and create reusable testing tools and libraries. My work has included launching widely adopted features, reducing regression cycles, and establishing QA practices as a first hire in early-stage teams as well as scaling quality in fast-growing organisations.
