Netscape Communications Corporation (AOL), Mountain View, CA

Senior Software Engineer

Developer of international text layout features
  • Assessed AOL project requirement and architecture documents from the international point of view, giving feedback on both the technical level (e.g. problems of data integrity and encoding conversions) and the cultural level (e.g. issues with the different format of dates in the US and Europe).
  • Created localizable and customizable version of the Talkback error-tracking tool. Designed and implemented a technique for runtime loading of localized UI strings from a plain-text configuration file. Handled issues arising from different configuration of UI fonts in different systems.
  • Analysed performance of Mozilla layout code with Rational Quantify and found solutions to performance bottlenecks.
  • Provided consultation to the open-source community of contributors to Mozilla on internationalization issues.


IBM Global Services Israel

Software Engineer

Worked on right-to-left support for IBM and external projects.
  • Added Right-to-left UI capability to Windows applications.
    A client who was developing localized Hebrew versions of English applications for the Israel market required the user interface to be adapted for right-to-left layout, without access to the original source code. Developed a layer between the application and the system libraries which converted the screen coordinates and other parameters and flipped the direction of the interface elements on the fly.
  • Bidirectional ActiveX text control.
    As part of a client-server project for the HR department of Intel's new facility in Israel, text entry in Hebrew was required for use in Visual Basic applications, which was not supported in the text box widget of the version of Visual Basic available at that time. Designed and implemented an editing control with support for mixed left-to-right and right-to-left text.
  • Implemented the Bidi (Hebrew and Arabic support) for Netscape 4.x and Mozilla in a joint project with IBM Egypt.
    Learned the Mozilla layout engine and added support for right-to-left document layout and reordering of bidirectional text, even on platforms without native Bidi support. Drove the integration of the code through the mozilla.org review process and into the source tree. See my paper "The Story of Bidi Mozilla" from the 22nd Unicode Conference, San Jose, September 2002.

Designed an implemented a system for the BBC Master computer which included definition of calligraphic Hebrew fonts, design of blank diploma forms including graphics and merging names of graduates from an external file in IBM format, and printing the diplomas on a laser printer.
