Apple – NeXT Software, Inc.:
January 97 – December 1998
Engineer: Mac OS X Printing group. I was responsible for printing under Mac OS X Server (shipped product). This included several applications and modules: Printer Manager App (in Java), 2 printing daemons (one Objective-C and one a minor LPD port), Printer Driver (Objective-C, loading driver bundles for specific printers). I also worked on IPP Server (Internet Printing Protocol) written as a Java Servlet (not shipped).
July 95 – January 97
Senior Engineer: Premium Developer Support (NeXT). I was the lead contact for up to 6 accounts, responsible for answering their Objective-C design or implementation questions. This was done typically by supplying correct programming examples, bug workarounds, or patches. I also routinely submitted/verified bugs to engineering and contributed significantly to two patches to our products (gathering/verifying/supplying fixes, justifying patch). Was the support contact for the ‘USPS project’ (the largest EOF project during the beta and rollout of EOF 2.0) until promoted to engineering.
Lender’s Document Service:
March 1991 – September 1994 (Full-time)
October 1989 – March 1991 (Part-time/Summers)
I was the programmer for a legal document printing service. I developed, wrote, and maintained programs in Objective-C, using PostScript to print. Suite included several modules for data entry, a module to do the ‘APR’ calculations, and a module to parse the forms and merge the data for output to the printer.
I also developed, wrote, and maintained an automated client-server system for 40+ customers in remote sites. This system was ‘served’ on a NeXT (unix box) and was largely written in Perl; it was responsible for automatic billing and file updates for the clients. I wrote several NeXTStep (Objective-C) apps for use in-house to help manage client systems. This system remained in active use for more than a decade.
