  • Grew the development team to a cross-functional group of 10 people, including 4 developers.
  • Project is rooted in previous improvements, beginning in 2002, to the presentation of examples in MATLAB. This included automatically publishing MATLAB scripts (see below) during the product build using MATLAB and gmake and presenting the HTML in the Help Browser using XSLT.

MATLAB Publishing Developer (2002-2011)

Principal designer and developer of MATLAB Publishing. This feature creates rich documents from MATLAB code by recognizing markup in the comments and running the code to collect its output.

  • Implemented mostly in the MATLAB language, additionally XSLT is used to generate the HTML and LaTeX, FOP to create PDF, and ActiveX for the Word and PowerPoint formats.
  • Collaborated with the MATLAB Editor team on the design of the corresponding UI enhancements, especially code “sections”.
  • Related to this work, co-authored patent US8762956, Generating a report document from code.

Internet APIs Developer (2001-2005)

Designed and implemented APIs to access the Internet from MATLAB.

  • Developed a suite that included accessing URLs, sending e-mail, connecting to FTP sites, autogenerating a SOAP client, and reading/writing zip files. Implemented in the MATLAB language and built on top of core Java classes and libraries from Apache Commons.
  • Served on the Language Design Team.
