I'm a 100% bilingual Full Stack and Automation Engineer with over 20 years of experience working with US-based companies.

Regarding Web Development, I specialize in Wordpress, PHP and Java, and I have thorough experience integration with 3rd party APIs, like payment gateways and social media sites.

This enabled a suite of almost 300 regression tests to run in under 15 minutes, enabling the development team to run full regressions on the sites multiple times per day.
