Developing an advanced GIS data visualization tool for the Networked Naturalist project (http://networkednaturalist.org/). Framework allows on-the-fly creation of end-user definable data layers, with support for multiple user session. Uses Adobe Flex, Google Maps Flex API, UMN MapServer, and PostGIS.

Developed a PHP server side collaboration solution to allow developers using a certain debug tool to upload bugs, test cases, and error information to a server automatically. Solution integrates SVN functionality along with bug tracking, allowing developers to check out arbitrary versions of code that other developers submitted. Diffs are used to track areas of source code where problematic bugs exist.

Performed transient signal analysis on piezoelectric linear actuator to optimize physical displacement in response to input pulse. Involved measuring displacement with lasers at the micron level and Photron high-speed camera to view physical characteristics at the microsecond level.Wrote program that interfaces with the company’s oscilloscope; program sets oscilloscope parameters, remotely initiates oscilloscope operation, captures waveform data as voltage vs. time, and performs fast Fourier transforms and other project-specific analytical tasks on the data automatically.

Developed a prototype interactive campus map system using the ArcGIS Server framework developed by ESRI. ArcGIS Server offers a set of COM objects that allow management of geospatially correlated data, and has a Java API that wraps calls to these COM objects within network requests. ArcIMS subset supports display and retrieval of geospatial data objects through a proprietary XML AJAX implementation. Data is stored in a database, accessible by proprietary API as well as JDBC. I was responsible for the full implementation of the project. Project included:Initial implementation on Linux using Mainwin (Com/.NET to J2EE port done by ESRI), followed by native Windows implementation.Integration of GUI framework using JSP and JSF and customized implementation using GWT (Google Web Toolkit) to allow additional geospatial data manipulation.Utilizes the Java Application Development Framework for visualization, and ArcObject components for specific analytical tasks. Developed on ArcGIS Server 9.2.

Created a script engine, written in Python and Java (Jython), to automate stress/functionality testing of the company’s web pages. Developed system provided a great increase in both usability and execution speed.
