At TELECOM Personal (CFOTech IT Global Services), I design and execute Gherkin test cases, perform functional and end-to-end testing, and validate data with SQL Server. I also created a Confluence agent to search for squad leaders.

At Nextbyn, I tested a web ERP system and automated tests with Katalon Studio, integrating with Jenkins and GitLab. I worked within a Kanban methodology.

At Globant, I worked across web, mobile, and desktop testing, including APIs and backend systems. As QA Lead, I led and mentored a team, estimated effort, and reported on quality and risks.
