At ULTRA GO - LINEX TRAVEL, I lead the automation plan for Core Legacy and migrated automated tests from Mabl to Playwright.

I create AI agents to analyze user stories and generate test cases, and automate API tests with Postman to validate integrations.

My QA work also includes performance, load, and stress testing, as well as agentic workflows for bugs, incidents, regressions, and certifications. I implement conversational agentic flows on Wolkvox and build internal applications with Vibe Coding to optimize team processes.

Previously, as QA Engineer - Lider QA at Leal Colombia SAS, I implemented automation strategies and integrated AI into QA processes. I also used Cursor for code analysis and CI/CD pipeline validation and approval, and mentored new QA team members.
