2002-2008 Cybermation/CA Toronto, Canada
  Principal Software Engineer
  • Responsible for the development of the Unix "agent" portion of Cybermation job scheduling software. This key component interacts with all aspects of Unix and runs on Linux, Solaris, HPUX, AIX and Tandem. Portability and thorough knowledge of Unix was critical in this role. It became our motto that "if this Unix variant has a bug, we'll expose it".

  Senior Software Engineer
  • Designed and implemented content entry engine of BroadVision Content Catalyst, a Java/JSP/JavaScript based thin-client XML content management system running under the BroadVision 1to1 Enterprise application platform.
    • Designed and implemented from scratch, including automatic regression tests.
    • Led design and code reviews
    • Investigated, obtained, set up and maintained development tools for the rest of group and performed other systems administration functions
    • Responsible for end-to-end internationalization functionality
    • Interviewed job applicants and assisted the screening process
    • Tools and technologies used: JAXP, SAX, Xerces, Xalan, CVS, Java, Java Servlets and Beans, JSP, JavaScript, BroadVision Enterprise 1-to-1 on Sun Solaris 2.7, HPUX 11i and Win2k, Oracle, Apache and iPlanet
  • Designed and implemented portions of the standalone Win32/MFC/COM based precursor to BroadVision Content Catalyst.
    • Tools and technologies used: MSXML, Win2k, Visual C++ 6.0, MFC, COM, MS SourceSafe 6.0

1998-2000 Interleaf Inc. (now part of BroadVision). Toronto, Canada
  Senior Software Engineer
  • Designed and implemented module of the printing subsystem of BroadVision QuickSilver (formerly Interleaf 7), a structured publishing system.
    • Solely responsible for design, implementation and testing (rest of team in Boston)
    • Task involved using the XSLT transformation language to generate XSL flow object page descriptions and converting them into QuickSilver's low level typesetting language
  • Systems administration and networking during office transition.
    • Set up and maintained ad-hoc network gateway between Toronto and Boston office in tandem with other software development tasks.

1990-1998 SoftQuad Inc. (part of Corel). Toronto, Canada
  Senior Programmer
  • Solely responsible for Motif port (in C++) of SoftQuad Panorama, an SGML viewer.
    • Designed and wrote a complete HTTP 1.0 implementation for it from scratch
    • Technical liaison with third party technology provider. Provided design assistance and initial MS-Windows porting work
    • Subsequently rewrote it to be a Unix Netscape Plugin
  • Responsible for a large-document fragmenter/CGI-retriever suite (C++), which worked in conjunction with Panorama to let one efficiently view arbitrarily large SGML documents.
  • Co-designed and implemented the PSI Portable Scheme Interpreter, an R4RS compliant implementation of the Scheme Programming Language, designed to be portable from anything from MSDOS to MS-Windows to Unix.
    • Designed and implemented PSIOOP, an efficient object-oriented language extension with first-class objects for PSI written in C.
    • Integrated the PSI Scheme interpreter into SoftQuad Author/Editor (an SGML editor) allowing C++ classes to be treated as Scheme classes and vice-versa. This system became the core of SoftQuad Sculptor, a script-customizable SGML editor. This in turn is what was used to develop SoftQuad HoTMetaL 1.0, the world's first HTML editor and SoftQuad Apex, a specialized tool for editing electronics spec sheets.
    • Designed and implemented a BSD sockets interface for PSI.
    • Designed and implemented a generic interface for PSI allowing one to call arbitrary MS-Windows DLL functions (32 and 16-bit).
    • Designed and implemented the SoftQuad SGML Transformer (in C), which allowed SGML to be processed via Scheme scripts. This was used extensively in various contracts.
  • Designed and implemented SoftQuad sqlm, a C application which turns SGML into customizable troff, suitable for typesetting. All SoftQuad software manuals were produced using this.
  • Designed and implemented dtdocumenter, a PSI/C application that reads a DTD and outputs a skeletal SGML file with cross references and content models, suitable for producing documentation.
