engineering infrastructure lead @ keeping the check-ins flowing From March 2010 to Present (5 years 10 months) Committer @ Lift is an apache open source licensed web framework written in scala. It's 100% awesome and pretty much guaranteed to rock your world if you're into creating sites with highly interactive ajax controls, server side push using comet, rest apis, and, well, any other sort of web interaction. From 2009 to Present (6 years) Software Engineer @ Built udorse.com and wee bit of topguest.com. I spent most of my time working on the server side web architecture using the scala web framework, Lift. From July 2009 to February 2010 (8 months) Vice President @ I worked on the Risk Cache, a custom built reporting tool of monetary risks associated with ongoing trades and positions. Trade and simulated pricing data from various sources are co-located into Java process heap to allow for arbitrary queries by end users over a web interface. Data requirements which exceeded limitations of commodity hardware required move from single process to distribution across multiple servers. I created the data chunking, loading, and recovery framework for pricing data. - Built an arbitrary operation distributed execution framework to send computes to data and aggregate results (basically map/reduce). - Built a parallel calculation graph engine to optimize data loading utilizing the Fork-Join task library In role as "core developer", helped to enforce coding standards and test coverage. I also mentored junior developers and gave OO and Java development presentations. We took pride in greatly increasing automated build success rate by faking out external services and databases. From June 2005 to April 2009 (3 years 11 months) Analyst @ I was a software developer within the Digital Markets group. We created plumbing to other services such as reuters and bloomberg. These were gateways written in Java to allow our proprietary trading platform to communicate via quirky TCP socket protocols. From July 2004 to May 2005 (11 months) Software Engineer @ - Worked on R&D Voice over IP (VoIP) conferencing project as part of training. We created a Java based web service and application code to facilitate call processing on VoIP application server. - Worked in recreation of the myqwest.com customer portal in order to achieve greater performance, uptime and usability. - Built the core user account management Web Service in C# that co-ordinated and synchronized data across an Oracle database and a TIBCO bus exposed legacy service. I also created a data access architecture and supported development efforts of external teams that utilized the framework. From August 2003 to June 2004 (11 months) Software Developer @ This was my first job after college and probably my biggest solo (mostly) accomplishment. I was a bit heartbroken to find out that my efforts were recently retired from service in favor of a more modern hardware/software stack. We created a palm pilot application to allow healthcare staff to input wound treatment assessments electronically while seeing a patient and then later synchronize that data with a web based system. The palm pilot app was written in C, the synchronization conduit was in Visual C++, and the server side was in Microsoft's ASP (pre .NET). From May 2002 to July 2003 (1 year 3 months)
