ArgentinaWhat I'm looking for
I’m a QA Automation Engineer with 5+ years of experience in manual and automation testing across web, mobile, and AI-powered platforms. I’m passionate about quality strategy, test automation, and continuous improvement.
As the sole QA owner on cross-functional agile teams, I’ve covered everything from story refinement to release sign-off. I work end-to-end: functional, regression, and exploratory testing across multiple platforms and devices.
My automation and API strengths include Playwright (TypeScript and Python) and Selenium (Java), plus REST API validation with Postman. I also validate data integrity through database testing with PostgreSQL and MongoDB.
In agile/scrum environments, I’ve owned full quality processes, maintained automated test suites for critical user flows, and tracked 10–30 defects per sprint—reducing post-release issues and improving release reliability. I bring a practical QA perspective to sharpen acceptance criteria and improve execution quality throughout the sprint lifecycle.
