Professional Experience

2006--Present Software Engineer
Dow Jones MarketWatch, Minneapolis, MN

Team member on the 6 member Minneapolis Market Data redesign project. This project replaces all Dow Jones data feeds and core SOA web services relating to the distribution of financial data, this projects end goal is to make the indexes more reliable, faster and easier to maintain. It was intended to replace an overwhelmed system.

Our team was responsible for entitling all requests for data. Tens of thousands of requests per second come into the system. Our code checks whether the client is authorized to see the requested data, and returns the authenticated elements of the quote.

The project uses gSoap, C++ , XML, Java, JINI, Gigaspaces, Ruby and Ruby on Rails. The environment is a large cluster of linux servers spanning redundant datacenters.

• Designed, developed and deployed a Jruby based Ruby on Rails management interface for Financial data feeds. This tool administers the entitlement of all Dow Jones, WSJ, and Marketwatch data feeds. It allowed changing of complex nested java objects stored in a Gigaspaces data cloud. The administrative tool uses Ajax to manage complex data objects, this allows the user to easily change nested objects with multiple related objects easily and transparently. Early iterations of the project relied heavily on REST based custom web services. Later iterations used Jruby, as JRuby became production ready.
• Wrote and tested various aspects of the project in gigaspaces
• Used REST, JRuby, Java and Rails to manage data in a Gigaspaces object datastore. Wrote Java interfaces for Gigaspaces. Wrote XML serializers for Gigaspaces and REST datasources.
  
• Wrote a scripting API to Gigaspaces using JRuby. The API allows easy changes to data stored in Gigaspaces.
