MexicoWhat I'm looking for
I've delivered manual and end-to-end API testing at OneInc, using Postman while supporting release pipelines through GitLab, TeamCity, and Octopus in Agile Scrum teams.
I use AI-driven workflows with Cursor, MCPs, and custom prompts to streamline test case generation, API validation, and documentation. I also apply root cause analysis and issue tracking to support high-performance deployments.
Before software QA, I improved supplier, customer, and process quality at Sensata Technologies, Nidec Mobility Mexico, and ROKI Mexico. My aeronautical engineering background and automotive quality experience shape my focus on compliance, corrective actions, and continuous improvement.
