Summary

Mr. Chang has over four years ABAP/4 development experience in SAP R/3

application modules including SD, MM, FI, PP, EDI, RFC, and Bar Code,

plus over nine years programming experience utilizing C, C++, Unix,

PC, OS/2 in Communication and GUI design. Mr. Chang has developed a

unique programming technique in performance tuning, e.g. to manipulate

two of the largest tables MSEG and BSEG so that the speed can be

improved 10 to 100 times faster.

Mr. Chang wrote numerous customer programs in SAP application modules.

His expertise includes Developing Transactions (includes Screen

Painter, Menu Painter, Import/Export, Parameter ID, Message Class,

Screen Sequence Control, DB Tables), Interactive Reports, BDC

Conversion, SAP Script, Data Dictionary, Event Process, Batch Job

Scheduling and using INDX cluster table and Correction / Transport

System, Authorization, ABAP Query, Open SQL, FTP, and knowledge of

IDOC

One of his earlier SAP R/3 experiences was to fix a complicated Time

Forecast Program Hewlett Packard. The original program was written in

COBOL and did not function correctly. Mr. Chang rewrote the entire

program in ABAP Control Break style and won the tittle of "ABAP/4

Master" after the HP Division in Germany evaluated the program as a

"superior contribution".

Mr. Chang's next assignment was with Behring Diagnostics Inc. (Syva)

to take over one of their most crucial SAP modifications designed by

consultants of SAPAmerica at Philadelphia. The programming part was

handled by consultants from one of the `Big Six' firms who claimed to

have four to five years' experience. Although Mr. Chang only had

several months' experiences then as an ABAP developer, he figured a

way to make the modifications work seamlessly within four weeks

(7daysx15hours per day).

Later at 3Com and Samsung, Mr. Chang rewrote several programs that can

run ten to one hundred times more efficiently. Managers at Samsung was

so impressed that Mr. Chang was assigned to oversee and to program the

entire development and production support of their MM module.
