| MAJOR PROJECTS | ||||||
|
||||||
|
||||||
|
||||||
|
||||||
|
System Communicator 12/01 - 01/02 Developed a control software using API and task scheduler to communicate with ALLVIEW applications’ behavior and schedule the execution time for these applications. These ALLVIEW applications were EMS, SITE, Virgos, NIM-ER, EMP, MESA, NightHawk, ELF, RSB and InFoBank. This project was to design the process flows of these applications, program functionality of these applications and integrated these applications with the System Communicator. The PIPE technique was applied on the System Communicator for communicating with these applications. |
||||||
| West Region ALLVIEW/ERM Distribution Requirements 05/01 - 08/01 Developed four project components: SPL, AUTO, EMAIL and CD-ROM, using XML and FTP technologies. SPL and AUTO were paper distribution of drafted completed Job Drawings to customers. The system automatically queried the database, retrieved images of the specified issue or higher, overlay label information, created a print job and sent it to the designated remote printer. ALLVIEW provided an error report of the requested images that were not attached/imported and available to be included in the original print job. |
||||||
| BERS – Bug/Enhancement Report System 08/00 - 10/00 Developed a system bugs/enhancement report application for all systems in production. It was developed to report or record system bugs/enhancement problems, thus, improving the quality of active systems and establishing communication between administrators and users. |
||||||
| DTSP – Data Technologies System Platform 04/00 - 07/00 Participated in the design of the DTSP RTxe "DTSP RT" database and the development of the web-based system platform. DTSP was a warehouse for both Lucent and non-Lucent CAPRIxe "CAPRI" type orders associated with implementing solutions for ADSLxe "ADSL" at BellSouth Remote Terminals. It was developed to replace the multiple Excel spreadsheets being used to track those orders and give a single source of information for all nine states implementing ADSL. It was intended to give users some functionality on Information query, Data Entry, Data Update and performance reports. This project used platform independent code in accessing an MS-SQL server through Open Database Connectivity (ODBC) application program interfaces (APIs).
