Worked on RCRMS and COE, web applications for risk analysis and incident reporting when transporting hazardous cargo via railway.● Used C#.Net async/await pattern when accessing the database to improve performance and responsiveness of the system.● Created a Windows service in C# to monitor the database and automatically kick of batch processing.● Maintained GIS enabled website written in Silverlight and C# using Entity Framework for data access.Worked on Hazus project for FEMA as a sub contractor to IBM. Work was done in C++, C#, VB, and Transact-SQL.● Fixed issues with Core of Hydraulics, a C# process that analyzed raster elevation data to determine river locations and floodplains.● Maintained legacy user interface written in C++ and VB.● Migrated data aggregation processes to Transact-SQL in SQL Server database with an emphasis on improving performance of the study region creation.

PlacardPass is a cloud-based solution that replaces manual processes in the supply chain to assess regulatory compliance (i.e., hazmat placards, shipping papers). It is designed to operate in many operational environments including facility, port, and rail in-gates. PlacardPass validates shipping papers and placards, in-real time, and makes recommendations for in-gate acceptance. PlacardPass also provides guidance on compliant placard options prior to transportation.

Worked on Network Engineer, a telecommunication facility mapping and management programbased on ESRI’s ArcGIS platform.● Designed a subsystem to create and manage work prints used by telecommunicationengineers to manage work done by field crews. Led a team of 4 developers to implementthe subsystem in C#.● Reimplemented a custom renderer in C# to display map data using telecommunicationindustry standards. Performance of the new renderer was improved by 15%.● Worked with 4 other developers to make Network Engineer functionality available on theweb. Rewrote core pieces of the product using C# to be context independent so thesame code could run on the desktop and the server. Functionality from the server wasexposed via REST to provide support for multiple clients.● Worked with one other developer to define the public API used to customize and extendfunctionality for Network Engineer on both the desktop and the server.● Worked on a team that implemented software development process improvement usingtools such as: Resharper, FxCop, unit tests with Rhino Mocks, self-documenting codewith SandCastle, and integration tests.● Implemented web client functionality in C# to retrieve map features using REST calls andto manage the features in a client side cache.

Worked on HUD contract to provide a web application used to manage non-profit properties andorganizations.● Worked on a team of three developers to create a secure web application in ASP.Net.Web site performance and responsiveness was achieved using AJAX.; Worked with AMDWS group (Mission Systems) to provide threat detection and analysis (nearreal-time) to troops integrating data from multiple systems.● Maintained legacy C code on Unix to fix bugs in the existing software identified by thecustomer.● Took the initiative to evaluate mapping tool kits for the replacement of legacy software.Prototyped a new system using C++. Threaded the prototype application to achievemaximum performance in integrating inputs from multiple sources.

Founding developer for G/Technology, a utility mapping application. ● Responsible for maintaining the database interface used by the entire application to fetch and store data. Work was in C++ and interfaced with an Oracle database via OCI.● Designed subsystem to graphically present facility data relationships and attribution to the user, including hooks for customization. Led a team of one other developer to implement the subsystem in C++ and Visual Basic.● Designed and implemented technology used for all feature data moving through the system. Work was in C++, and included message management for keeping data up to date.Worked on GeoMedia, a GIS package.● Independently wrote the prototype framework to provide proof of concept for using COM and C++ to create a modular system.● Designed and wrote the feature placement system in C++ used to capture user input to create new map features.● Created a series of modular data “pipes” in C++ used to add value and functionality to data as it came out of the database. The interface was designed in such a way that the output of one “pipe” could be used as input to the next.Worked on MGE Network Analyst/Segment Manager used to manage utility and transportation networks. Work was in C on a UNIX system.● Wrote algorithm to manage and navigate a node-edge connectivity model in C.● Created hooks that allowed software to be customized via scripting language.● Prepared material and conducted a training class for customers on software customization.Worked on SeaVue, ocean floor mapping software based on sonar soundings.● Wrote preprocessing tool in C that took bulk sonar data and used statistics to thin it to a level that could be consumed by the rest of the system.Worked on a secure government project involving mapping using aerial and satellite imagery.● Worked on UNIX operating system. Responsible for design, implementation and maintenance C code.● Worked with customers to gather software requirements.
