At SABRE / YUXI GLOBAL, I designed and built a Java 17 test automation framework from scratch using Selenium and Serenity BDD. It automated 200+ critical test cases and reduced regression cycle time from 7 to 3 days.

I also engineered integration tests for REST APIs and microservices, achieving over 80% test coverage across core production services. I integrated the test suites into Jenkins and Docker CI/CD pipelines to support continuous testing and stable releases.

Earlier, I developed Java backend services with Spring Boot at MICHAELPAGE and worked across Java, REST and SOAP services, PL/SQL, and databases in roles at SCOTIABANK, ASESOFTWARE, AYESA COLOMBIA/ TIVIT SYNAPSIS, GLOBAL HITSS, and HANCO TECHNOLOGIES COLOMBIA SAS.
