Elba Alvarez
@elbaalvarez
I build reliable mobile and web test automation for fintech products, from frameworks to release-gating CI/CD.
What I'm looking for
At Zigi, a fintech app partnered with Banco Industrial, I built the QA automation architecture from scratch across 10 end-to-end services, including onboarding and home modules. I maintain a 112-case regression suite that gates every production release at a 92% pass rate.
I automate mobile and web flows with Appium, Selenium, and WebdriverIO, and connect Docker-based tests to GitHub Actions, BrowserStack, and Testmo. I also test REST APIs, performance, code quality, and OWASP-aligned security while completing an M.S. in DevOps.
