First experience with native android programming; committed meaningful changes to the project within the first few days, learned the framework thoroughly as well as many libraries and techniques to create performant apps. Over the course of the project started from Activity-oriented design, then migrated to a Fragment-based design, and finally into a View-based design with the Flow library.Participated in design meetings and contributed ideas for layouts and features which were later approved for implementation. Maintained unit tests using Robolectric and some end-to-end tests using the Robotium framework. Wrote scripts (with JS+Node, personal choice) to generate language translation XML files from our translation API, to generate icon assets for various screen densities from common source icons in PNG and SVG format, and other miscellaneous tasks.

Designed and implemented utility for managing a type of ID codes connected to the main customer database, which performed automatic data integrity checks where possible. HTML5, LESS and JavaScript on the client, Python with Django on the server.Maintained and developed new features for internal call floor software, tightly integrated with the Interactive Intelligence Inc (I3) auto-dialing phone system. Used I3 documentation to prepare tool for phone system version upgrade. Made the design decision to transfer several types of hard-coded configuration details from sourcecode into the DB. Developed several new features to meet evolving business requirements. HTML5, LESS, with Backbone.js on the client, Django with Python on the server.

Developed competency with the Neko Media Engine despite a general lack of documentation and maturity in the tools. Developed a design with an artist, and engineered the design in HaXe. Performed several optimizations for mobile platforms, including optimizing drawing calls for OpenGL and hand-coding certain shaders not supported on the mobile platforms. Released one game running on iOS 3.2, Android 2.2, and Flash Player 10.1 platforms. Coordinated development of promotional materials and release on Goolgle Play and the iTunes store.

Designed and developed a system of tools to simulate television- and internet-based content viewing, and record user interactions for analysis across experiments. Saved man-hours and human error stemming from creation of content playlists, and enabled integration of more interesting methods of interaction with content. (Adobe Flash CS5, ActionScript 3.0)Designed and developed a comprehensive tool for aggregating and analyzing data from multiple eye-tracking hardware systems. The tool consolidates several XML and CSV eye-data formats into a single binary format for efficient loading and transformation, then allows several types of queries to be performed on sets of these records, and allows the results to be exported in a standard SPSS-friendly format. Consulted with researchers to determine requirements and design, and developed a set of auxiliary features to expedite analysis, reduce the number of data conversion steps, and reduce the number of required Research Assistant tasks. Integrated Windows Media Player as a COM component to avoid a costly video conversion step, caused by one eye-tracking system which exported video with a proprietary codec. (Java 1.6, SWT for native UI)Maintained and developed features for the company's internal participant- and experiment- management system, after it's primary developer unexpectedly left the company. Developed basic competence with Python, Linux, and web programming concepts to take over this work. (Python 2.6, HTML/JavaScript, SQL)Developed miscellaneous utilities to automate Research Assistant tasks, including a tool to quantize eye-tracking data into 1-second records and a tool to scan and catalog lab equipment by barcode.
