Ported and shipped CD burning library used by iTunes and Finder within six weeks of hire

Migrated CD/DVD burning library to a new, young operating system and helped develop missing system services

Served as point of interaction with applications group, visiting them in person to help work out problems using the burning APIs.

Developed a new API, building upon client experience, for burning CDs and DVDs. This API was released to the public with Mac OS X Jaguar.

Increased performance with new APIs and services

• created "burn on the fly" API. Performance improvement varied from 2x - 10x.

• created filesystem generator API to allow full flexibility when creating filesystems.

• implemented filesystem generator using burn on the fly. Performance improvement varied, but generally several orders of magnitude. (eg, typical pattern reduced from 20 minutes to 15 seconds.)

Filed patent for filesystem generator API. (currently pending)
