Lead Senior Software Engineer for the Access, Entitlements, and Credit Card ServicesLead developer for the company-wide entitlements and compliance system. This system controlled client level, tier level, and individual user level compliance across any platform of data retrieval. The core decision making library is required to quickly make access decisions for high volume quote, document, news, and other data requests. The system was designed to be scalable to handle both growing volume and complexity of requirements. I was also responsible to upgrade and implement the company's Credit Card Processor system which was based on Pay Pal’s merchant services. I added capabilities for in-house subscription services without retaining end users credit card numbers.

Implemented Reuter’s flagship realtime financial ticker and news feed, Reuters Market Data System (RMDS) for the larger organization. This project required an extensive mapping and rules library and engine to ensure that data normalization was possible as the company’s need for breadth in market data grew. Solely architected and implemented the configuration based approach, built from the ground up and provided the basis for all future feed development within the team.Engaged, onboarded, developed, and maintained a series of feeds through a suite of applications that interface with third party vendors that provide consolidated real-time and delayed market ticker data. Directly worked with data vendors Sungard, Telekurs, and Thomson Reuters. Oversaw and re-architected the mapping engine within the back-end quote server application. Normalized time series data collection and open, high, low, close aggregation.Designed and developed an application that simulates trade order processing that was used for a handful of stock market trading games and competitions.

Student Systems Administrator at a well respected, federally funded reasearch labratory while studying Computer Science at the University of Colorado. My hobby background experience in administrating the Linux operating system provided me a solid job learning how to stich together all major Unix platforms for a software build environment. I actively worked on centrally managing 30 workstations and 20 servers. Implemented Windows Active Directory support and incorporated LDAP/Kerberos to extend authentication into the Unix platforms as well. Established solid backup routines, automated patch updates, maintained password management, and generally kept a smooth running shop for a small office group of researchers.My most notable contribution was replacing an big iron sun server running UCAR's primary LDM server with a cheaper distributed solution. This project was self promoted and implemented which eventually replaced the single Sun server costing more than $250,000 with five commodity x86 based servers and an open source load balancer (LVS) costing a total of $25,000. I was offered a full time position as a Systems Administrator II one year prior to graduation, however, I declined and followed through with my education as a software engineer.
