    Ethan Willis

    Full Stack Javascript Engineer and Java Guru

    United States

    Hello, I'm a professional software engineer with enterprise experience and the theoretical knowledge that comes along with my B.S. in Computer Science. I've succesfully battled my way through programmer purgatory to come out on the other side, to serve you. I've got an extensive background and passion for web technologies first and foremost. I do backend work in PHP, Javascript, Meteor.JS, and Node.js. On the front-end I've got over a decade of HTML and CSS experience, but I wouldn't mind working on Famo.us interfaces with you :) Web technologies don't always pay the bills however and I've become highly skilled with more traditional environments as well. I've been developing in Java for about 7 years now in academic and enterprise settings. As well, I've picked up Salesforce.com development skills as I've been working towards integrating legacy Java applications with the Force.com platform. If you need anything related to Apex (triggers, classes, etc.) and/or Visualforce, I've got you covered!
