What I'm looking for

I want to grow as a QA automation engineer, owning Playwright/WebDriverIO and API test frameworks, collaborating with developers in Agile/Scrum, and strengthening CI pipelines so releases stay fast, stable, and well-documented.

I’m a QA Automation Engineer Jr. with a solid foundation in manual testing across ERP and eCommerce environments. I’ve built my automation practice around practical E2E, UI, and API validation, with a strong focus on requirements analysis, test case design, and reliable execution in real workflows.

I completed a JavaScript-based automation specialization (EPAM Systems, 2026), where I worked on E2E/UI/API frameworks using Playwright, WebDriverIO, and Supertest. I bring hands-on experience applying BDD with Cucumber/Gherkin and designing maintainable test suites that stay decoupled and reusable.

In my automation projects, I built an E2E/UI/API framework for Toolshop using Playwright, Mocha-Chai, Supertest, and TypeScript with POM + factory patterns. I created 27+ test suites (20 UI + 7 API), including API schema validation with Joi, configured parallel multi-browser runs, and added Jenkins pipeline stages for linting and automated test execution.

Before fully focusing on automation, I worked at MAVI de Occidente as a Senior Process Analyst and QA Manual Analyst, executing UAT and exploratory testing, writing SQL for data validation, and reporting/triaging defects in JIRA. I’m energized by teams that value clarity, measurable acceptance criteria, and disciplined quality gates from development through release.
