PROFESSIONAL EXPERIENCE

IBM, Austin, Texas

IT Specialist,    1997-2002

• Led technical team of 8 assisting in migrating large German financial customer with 40k clients and 8k new servers to current version of e-business server and WARP client.  Team provided assistance with testing, building images and code server, debugging, performance tuning, and method of migrating. Team participation was completed before the scheduled date.



• Successfully evaluated performance of retail customer’s cash register system, running WARP 4.0, which resulted in recommended changes to improve system performance.



• Resolved a large Canadian Bank’s performance problem by adjusting heap size in the executable using a binary editing tool. The customer did not have source for the application which would have been fixed by recompiling.



• Redesigned ‘C’ source memory analysis tool called Theseus to work without device driver support adding kernel APIs for WARP 4.0.

IBM, Austin, Texas

Advisory Programmer,    1993-1997

• Maintained inherited ‘C’ source PM program and INTEL assembly source device driver for memory analysis tool Theseus. Fixed problems related to changes in OS/2 system control block changes. Theseus was an internal tool which was released to allow customer usage.



• Performance analysis for LAN systems and OS/2 for 3 years and then worked on memory analysis tools using ‘C’ for OS/2.



• Worked in OS/2 kernel development, for 4 months, to improve paging I/O and steal task functions. Steal task code improved system performance from 2% to 5%, but it was not used.

IBM, Poughkeepsie, New York

Advisory Programmer,    1990-1993

• Team leader of 8 associates for an IBM Fellow (Research & Development) to code in ‘C” an application that would run on the mainframe and PC to backup files and to transfer data between the mainframe and the PC at higher rates using TCP/IP protocol. The TCP/IP protocol stack was emulated on the mainframe and executed on the PC to offload execution time. Performance improvement yielded reduction of CPU time from 75% to move 128k to 35% to move 450k of data between the mainframe and PC.



• Patent awarded for Network processor for transforming a message transported from an I/O channel to a network by adding message identifier and then converting the message.

IBM, Kingston, New York

Staff/Advisory Programmer,    1983-1990

• Led team of 4 in designing, implementing, and testing code for shared storage support for VM/ESA within the specified schedule.



• Designed performance improvements and fixed memory usage problems in VM/ESA paging subsystem. Redesigned volume initialization to point to a table of characteristics to reduce the code in the paging path to determine the volume type. Utilized suspend/resume 390 I/O function to reduce the time in I/O subsystem. Reduced time for page fault from 10k to 1,100 instructions by removing queuing mechanisms and need for extra storage.



• Designed and implemented performance improvements, in VM/ESA paging subsystem, for DB2 queries that improved performance from 2 to 300% using DASD mapping to memory. This allowed DB2 to indicate which pages would be referenced before using them so that the paging subsystem could bring them in ahead of time.

EDUCATION

• Completed 2 internet courses on Barnes and Nobles Web site for HTML and DHMTL. (December 2002 and January 2003)



• Attended IBM classes for Linux device drivers and kernel internals. (2002)



• Attended IBM class for MQSeries. (2001)
