MAJOR PROJECTS

iTunes Music Store was a radically new way of purchasing music online. My responsibilities included initial architecture of a pluggable content-importation tool for music (samples, metadata, cover art, the works), and an implementation of same for the Warner label; later I was responsible for design and implementation of the commerce model, credit-card authorization engine, integration with SAP, commerce UI implementation, and price modelling. After the initial release I was responsible for the commerce and much of the account UI components of 20+ and counting international stores, complete UI and architecture of a gift certificate/allowance mechanism, as well as a more recent mechanism for gifting music (patent pending). Throughout the project I was a principal architect and design leader. The iTunes Music Store has been Apple's most successful online venture, and the most successful online music store in the world to date.

iWork. Apple's productivity client applications for iOS and MacOS. Monolithic codebase, large numbers of developers, high levels of integration between subsystems. I wrote network integration layers, and syncing UI; it was a great way to get refreshed on modern iOS/MacOS X client APIs and practice.

iTunes U. Apple's e-learning solution. My involvement was mainly back-end data management and database integration.

.Mac. A suite of internet applications that provide Apple customers with the ability to painlessly enhance their internet experience. I was responsible for the design and implementation of the e-commerce underpinnings of the free iTools service's transition to the subscription-based .Mac service, particularly in the area of credit card processing, commerce UI, and SAP integration.

AreaJ. An open-source perl/mod_perl/mysql/apache/ImageMagick based suite of web applications for management, presentation, and editing of digital photographs.

Designer of a CORBA/java based object-management middleware solution for Resonate's second-generation product. Can't say more until the product is available.

Maintenance and new versions of Oracle's AWT and Swing-based Table objects; design and implementation of localized calendar UI object, Design and implementation of GanttChart UI object.

Infoscape FrescoDesigner versions 1.0 thru 3.x, and Fresco Frameworks. Infoscapeís FrescoDesigner is a complete database front-end solution, including tools for object-relational mapping, GUI layout and connection, as well as frameworks for complex database access. (1997, 1998).

Solaris Openstep. Sunís implementation of the OpenStep Spec developed jointly by Sun and NeXT. Openstep included a fully-featured application-development library that implements the NEXTSTEP look-and-feel, as well as the basic productivity apps such as a mail application and text editor. My work on Openstep included integration of new application-kit code, porting of NeXT's Enterprise Objects Framework (EOF), bug-fixing of existing code (mostly mail-related) and design and implementation of large parts of the sound subsystem. (1996). OpenStep and NextStep have since evolved into Apple's upcoming Mac OS X 'Rhapsody' Operating System.

McCaw Application Framework. This object-to-database persistence effort was an augmentation of NeXTís Enterprise Objects Framework (EOF). As part of a team of about 10 engineers, my responsibilities were to design, develop, fix, and maintain the GUI architecture and tools, including InterfaceBuilder palettes, re-usable interface objects, user-input validation subsystem, and GUI-side database interface code. Also was solely responsible for development and delivery of SecurityManager a table-maintenance application managing a complex schema. (1995).

MSMail Bundle. This is a bundle designed for use with NEXTSTEP 3.3ís Mail.app, providing the capability to send and receive Microsoft-format Mail. (1994).

TTools. A library/IB-palette combination designed as an advanced IB primer, released as a NeXT mini-example for the use of the NEXTSTEP developer community. (1993). Related speaking engagements at the East Coast Developer Conference, NEXTSTEP Expo and a feature article on IB-palette development for the NeXT-produced developer journal, NXApp (1993, 1994).

NeXT Premium Team Support. I designed and field-tested the delivery of a team support policy for NeXTís Premium Developer Support customers, so that I was able to return to school part-time to finish my degree (1993).

NeXTAnswers faxback software (team effort), a utility package that collates multiple documents in many formats, converts to PostScript, and faxes the result. In production as the back-end of the NeXTAnswers document-retrieval system (1993).

MeetingPlace. A NEXTSTEP group decision support system application. Helped design and implement a coordinated, multimedia object-sharing architecture for UBCís Commerce Department (1992).

FUBAR: Fully Unified Basic Appointment Resource. (Code Name). A UNIX/X11 application allowing individuals and groups to organize and integrate their schedules across a LAN. (1990, 1991).
