    System Engineer

    United States - Last active: 12/04/2014 - Tests: 2

    I'm a thorough and detail-oriented software engineer that can still talk to you in "plain English." I'm not afraid to ask the 'dumb questions' to make sure everyone is on the same page. My biggest focus has been on business process automation, data design, and systems development. Most of my development experience has been in Java, Spring and Grails, but I've worked in many different languages and environments in my career. I also have a background in cryptography, software security analysis, billing systems, and regulatory compliance (SOX, PCI) and auditing.
