	Sep 2002 – present Principal Application Developer Gallatin National Avalanche Center - Project SnowPilot n Single handedly designed, developed, and coded the ‘Snow Pilot’ application for snow science data collection. This distributed application is designed to allow the collection of snow science data in the field on PDA devices such as Palm Pilots, Windows CE, mobile phones or other devices. The data collected in the field on these devices can then be uploaded to the user PC for review and then is automatically sent over the web to a centralized database. Once in a central database, this data is accessed over the web via a J2EE app server by researchers and forecasters. This is a distributed application with several components on different platforms. I was the sole developer on this project and designed coded and integrated each component. n Designed and coded in Java the PDA portion of the application for the Palm Pilot platform using the both Waba and the J2ME/MIDP and framework. This portion of the application allows the collection of snow science data in the field by snow science professionals. Features include clean and intuitive GUI‘s for data entry, form and field level validation of data, customizable user preferences for units and data collection patterns, and graphical representation of data for in field validation. I worked closely with the scientist and forecasters at the National Avalanche Center to assure that this application met their very specific needs. n Designed and coded the PC portion of the Snow Pilot application. This portion was written as a cross platform Java application for PC, Mac etc. This portion of the application transfers the data from the PDA device to the users PC. The PC application allows data entry, review, storage and graphical viewing of the data, user validation, and sends the data to the central database via the internet. n Designed and coded the server side portion of the application to receive and store the snow science data from the various users across the web. This is a J2EE application running on Apache/Tomcat server with MySQL database. Designed database schema, wrote SQL scripts for the DB, built java applets for data display, and server side Java classes to receive and parse the serialized data objects. n See http://www.snowpilot.org for more information.
