10/2011-10/2013: Web Development
Worked mainly with JavaScript, HTML and CSS. The main focus is using JavaScript on both
the front-end and the back-end. The front-end is predominantly native JavaScript, CSS(3),
and HTML(5); but does involve jQuery, and sometimes Bootstrap, AngularJS, D3 and a bit
of legacy Prototype.js. The backend is Node.js. Non-JavaScript connective technologies used
are PHP and Java. Grunt is used to automate tasks.
Contractor at Sony: Used pure JavaScript to build a monitoring Web application for Sony’s
cellular products. The goal was to use standard technologies to build a large application
without Java, PHP and Ruby. The technologies used were: JavaScript, HTML, CSS,
AngularJS, D3, Node, and jQuery.
Contractor at Motorola: Worked on DreamGallery and TVE at Motorola/Arris. These are
large and complex Web applications using JavaScript, Node.JS and Java to deliver
entertainment to set-top boxes (TVs), tablets and smartphones.

Lead developer and owner of all the client-side (GUI / MVC) code for Easy Writer 2, a large
scalable mortgage application serving more than 30 wholesale branches, tens of thousands of
brokers nationwide, a retail branch, and an Internet-based retail operation. The application
automates the complex loan underwriting process, thus simplifying the work of AEs, LOs,
managers, and admins. It was tied into various services such as Pricing and Credit services.
I took feature requests from the business analysts, broke them down into small tasks, and
surgically integrated them into the application at the appropriate tier. My work often involved
all the tiers, from the GUI all the way down to and including the database tier. Many of the
application modules were done by me from scratch.
The application accepted and processed loan applications. Assets, incomes, liabilities, and
various conditions were input into the system. The system had a rules engine that processed
the inputs, along with special qualifiers, to render decisions and analysis.
Many reports and forms were available to the users on demand.
The technologies we use were Java, Servlets, JSP, EJB, AJAX (JavaScript, HTML, XML,
CSS, XMLHttpRequest, ActiveXObject), SQL, Oracle 8i/9i, JDBC, JDO, Struts, WebLogic
8.1, and Tomcat.
