SeniorJohn Perez is a Senior Software Developer with nine years of hands-on experience building and optimizing enterprise Java systems, currently driving backend development at Euronet Worldwide from Little Rock, Arkansas.

His background includes architecting HL7 and clinical data integrations and improving performance of JEE systems on WebSphere and JBoss, demonstrating both deep systems thinking and pragmatic delivery.
