El SalvadorWhat I'm looking for
At Freelance, I test mobile and desktop products across functional, regression, performance, and API testing. On Princess Dental, I validated deep links across iOS and Android, checking that links from messages and notifications opened the expected screens.
For Prospec, I designed and ran functional and regression tests for Schedule Visit and My Estimations, reporting business defects and UI issues in Jira. I also validated UX audit findings and prepared test case matrices for VITee.
At Rulesware, I participated in testing banking, insurance, time-tracking, and informational website projects. I analyzed requirements, created and executed test cases, tracked defects, and tested mobile applications within Scrum teams.
I use Claude and Claude Code to support ticket triage, test case development, documentation, and automation scripts, manually reviewing outputs before delivery. My background also includes teaching programming, web development, software testing, and equipment maintenance.
