• Leadership
  • Itron EE Architecture Team member (April 2004 - September 2004)
  • MV-STAR Architecture Team member (Oct 2000 - Aug 2002)
  • MV-STAR Systems team lead (Feb 2000 - Aug 2002)
  • Participated in Itron's 2003 leadership training course
• Software Engineering Process
  • Instituted new MV-STAR documentation requirements to ensure adequate documentation of new components
  • Developed branch and build procedures for MV-STAR and Itron EE
  • Adopted XP-based planning and steering procedures for Calculation Engine team
• Development
  • Reduced runtime of a typical MV-STAR report to less than 1/5 of its original runtime
  • Designed and implemented a component to centralize correct business rule handling for all MV-STAR reports that fetched reading data
  • Led the MV-STAR meter changeout project (design, requirements, etc.) to add complex date handling at the core of the system
  • Isolated and fixed a race condition in a batch file processing system
  • Discovered and fixed a critical bug in a job processing daemon involving non-reentrant code in a signal handler
• Java
  • Implemented a Java-based meter data acquisition product for the Ontario wholesale power market
  • Reviewed most designs for new components in MV-STAR
  • Prototyped and decided how team would use Java stored procedures in Oracle 8i
• .NET and C#
  • Implemented a C++ bridge from C# to legacy C code to preserve a C-based calculation engine after a product was ported to C#
  • Implemented pre-processing logic in C# for an ETL process for DAO product's datamarts
• Database work
  • Implemented an Oracle-based meter data acquisition product for the Ontario wholesale power market
  • Prototyped a redesign of an existing product to use TopLink for its data persistence
  • Researched multi-dimensional access methods for RDBMSs [at Signal Physics Laboratory]
• XML
  • Selected XML technologies for MV-STAR (SAX parsing, Xerces, etc.)
  • Designed XML Schemas for new interfaces
• Python
  • Wrote Python code to generate XML-based test data
  • Led effort to build a Jython-based automated regression test system for MV-STAR
  • Wrote Python CGI scripts for security auditing [at Signal Physics Laboratory]
• C and C++
  • Ported C++ code from Tru64 UNIX on Alpha architecture to both Solaris on SPARC and Linux on x86
  • Isolated and fixed a critical bug that corrupted reading cache files in MV-90 EE C code
  • Ported C-based "calculation engine," including a lex/yacc-based formula language, to a new platform
  • Modified components of a real-time active SONAR processing program written in C [at Signal Physics Laboratory]
• Training
  • Led C# training for Java developers (for some modules)
  • Helped lead a Design Patterns reading group
  • Helped lead a Refactoring reading group
  • Trained team in Perforce usage during a migration from CVS to Perforce
• Scientific computing [at Signal Physics Laboratory]
  • Analyzed accuracy of new sonar processing algorithms using MATLAB
  • Automated batch processing of actual and modeled sonar data by writing Python scripts
  • Created custom LaTeX document class corresponding to the lab's formatting standards
  • Modeled expected drift from plotted course using Perl and gnuplot
