I build intelligent QA automation and .NET solutions for enterprise and telecommunications applications.
ColombiaWhat I'm looking for
I'm currently building QA automation at Rockwell Automation, where I perform functional and regression testing for web and enterprise applications and streamline reporting through Power Automate flows.
At Tata Consultancy Services, I led Selenium, Cucumber, and Java test automation that automated 50% of manual test cases. I also translated requirements into Gherkin BDD scenarios, increasing test delivery speed by 70%.
I contributed to AI-driven testing by fine-tuning language models and developing intelligent agents for complex test scenarios. My work in defect analysis and proactive debugging reduced issue resolution time by 25%, while my C#/.NET unit testing increased code coverage by 85%.
Earlier at Skyline Communications, I built .NET device-management drivers for switches, routers, and CMTS equipment, improving data reliability by 50%. I enjoy building scalable automation where QA, AI, and software development meet.
