I wrote an engine to match orders made by users which then communicated to a trade engine that handled all the trading, stats collecting and presentation. Also wrote a piece of Java to read in XML stats files whose definition is somewhat fluid into SQL. Also wrote most of the Java bridge using NBIO, collaborating with the other Java contractor to ensure a system that was stable, reliable and scalable. Rewrote parts of it to eliminate the Jabber messaging if the bridge was running in the same JVM as the engine it was calling.

Worked on data imports using an in-house scripting system written in C++, SQL Server stored procedures and server to server calls. Wrote most of a new templating/scripting system in C# .NET to provide substantially similar functionality to the legacy system while using modern syntax. Wrote most of the language formal specification. Code was compiled to binary pcode to support obfuscation. Compiler was finished, interpreter was mostly finished, UI element generation and layout was mostly finished and working. Data model and back end were not completed.

Software Engineer, Uici
Worked on web-based administration for a custom insurance quoting app written in Java/Apache Struts with SQL Server back end. The administration piece allowed configuration of every data element in the quoting system, a substantial amount of data. Worked primarily in the business logic and data layer, troubleshooting performance issues as well as writing new code. Wrote components to import data from various formats generated by the legacy mainframe. Much of this data required substantial post-processing. Rewrote the datalayer and quoting engine of a legacy C++ Palm OS 68k app to use an explicit tree structure resulting in at least 15 times performance improvement and as much as 45 times on slower devices. Ported new quoting engine to Java which enabled a Java quoting system on Pocket PC.

Wrote a C++ shared memory manager using SYS V SHM in an attempt to make a very high performance connection pool for PHP. Wrote PHP admin pages. Worked on a PHP data layer to interface with either a database connection or the transaction engine.

Java Developer, Qpax.Com
Worked on a system to parse incoming PNR (Passenger Name Records, an free-form record commonly used in the airline industry) records, apply business logic to them and write the result to the database, which was Postgres, although with a flip of a setting, the code could use MySQL, Oracle or DB2 as well. PNR system was 24x7 mission critical, and had the ability to change almost anything on the fly, with its own telnet client that allowed inspection of internal state as well as the redirecting of the log to a file, the database or the telnet console. Errors were logged into the database for further inspection, allowing problematic PNRs to be loaded with a simple Swing utility once the bug had been fixed. Ported code from Windows NT to RedHat Linux to parse Noaaport (weather balloon) data in support of a weather prediction system. Rewrote the code in Java to enhance reliability, maintainability and scalability. Incoming PNR records were parsed into a holding table in Postgres and subsequently run through a series of tests and logic so that they were arranged in a statistically useful way. Project involved reading FORTRAN code to determine how the data should be arranged.

Java Developer, Bizblast.Com
Worked on the BizBlast.com core product, a system that allowed small retailers to gain a web presence, complete with shopping cart, accounting and payment. Handled the creation of a theme editor, an interactive page with multiple Java applets, with a templating system to render HTML. Back end was a Servlet connected to MySQL and a set of directories. Worked on extending the templating engine to provide greater functionality. Rewrote substantial parts of the templating engine to promote code reuse, maintainability and object-orientivity. The core system was in Java, and I used VI and VisualAge 3 on RedHat to do development.

Junior Analyst, Metrosplash.Com
Worked on developing a payment system for a classified ad site. Worked on the core business which was internet dating, converting the system from C/CGI to Java Servlets. Wrote admin pages and AWT/Swing code for administration. Instrumented the web system, which included a caching system, so that individual caches could be inspected for content, individual pieces removed, entire caches dumped or forced to reload. The front end was in Java/Servlet. Worked on the data layer including the caching piece, which completely abstracted the database SQL calls and forced cache coherency and reduced write load by only writing differences.
