Technical Manager/Lead Member

Responsibilities:

• Developed and enhanced a high fidelity simulation software, MEDUSA GUI for the AEGIS Combat Battle System for BMD 4.0.1, ACB12 and BMD 5.1 in C&D, SPY-1(Radar), WCS, and many other components. The backend processes were implemented by using C, C#, C++, Java, Python and the frontend processes were implemented by using Apache Server, Java Swing, JSP, ASP, Java Servlets, JDBC, Python, and Perl.
• By using Oracle ATG Web Commerce, I developed a Purchasing Procurement Software for Lockheed Martin to boost its cross-channel business growth on purchasing civilian products. This new software development of using Oracle ATG Web Commerce Feature, helped Lockheed Martin quickly find desired products, learn about new offerings, comparison shop, register for gifts, preorder products, redeem coupons, and easily complete their purchases.
• Developed and enhanced a high fidelity BMD threat simulation software, PROMEThEUS in BMD 4.0.1. The back-end processes were implemented by using C, C#, C++, Java, Python and the front-end processes were implemented by using Apache Server, Java Swing, JSP, Java Servlets, ASP, JDBC, Python, and Perl.
• Developed a Navy system, TSTS (Total Ship System) to Navy Yard Customers in Washington D.C. in a real time mode by integrating all existing simulators such as LMSAS, Gateway, OASIS, ACSIS, BRIDGE, and SCOT via HLA (CORBA) and socket programming in DIS PDU format. The back-end processes were implemented by using C, C#, C++, Java, Python and the front-end processes were implemented by using Apache Server, Java Swing, JSP, ASP, Java Servlets, JDBC, Python, and Perl.

As Lead Developer/Lead Tester

Responsibilities:

• Developed and tested an Interactive Web-based Rebate System for the telecommunication Port and PVC which was the Corporate Security System by using IBM WebSphere 4.x, WASD 4.x, Jakarta Web server such as
• Tomcat, JBoss, Apache Server, and Struts. Reporting cycle for the customer became interactive through the web-based implementation, eliminating the need for the customer to wait for an end-of-the-month report
• Reimbursement processing could then be done on a daily as opposed to a monthly basis.
• Developed and tested a central information bank for the billing, ordering telephone number assignment for new customer service departments, greatly reducing the time it took for answering customer questions and resolving problems.
• This was the first automated system for the "splitting" of telephone numbers into newly assigned area codes; ILEC Interface/Client Interface which Interacted whether through phone, e-mail or database means with other ILEC's like Verizon, SBC, MCI or SWBT
• Monitored Ordering & Provisioning to track orders placed with the ILEC's through databases; The provisioning part was the completion or engineering of the circuits ordered.
• The majority code of the development was written in Clear Case, CGI in Perl, IBM WebSphere 4.x, WASD 4.x, JAVA, ASP and C++ language in UNIX server side
• Visual Basic 6.0, VB Script, Visual C++, in window side by storing the data into Sybase 10.x, IBM DB2/UDB under Linux while transferring data from/to other connected system by using Connect/Direct.
• Developed and tested an innovative billing system by storing 2 years billing data for customers by using Teradata Veritas File System from the huge size of AT&T whole billing Big Data, which could be retrieved interactively - background processes to store tetra-million bytes of CDR billing data for 2 years into database and to retrieve them effectively by splitting 3 months, 6 months and remaining old data. CDW project resulted in the recovery of approximately $145 million in customer payments and significantly increased future billing efficiency.
• The fastest access data was stored in the hard disk while the rest of data was stored into the specially designed Hitachi Veritas File System for the fast access. Newly stored data less than 3 months old, was stored in Oracle 8.x database while the oldest data was stored in Hitachi Database using Data Warehousing of OLAP(Online Analytical Processing by using ETL(Extraction, Transformation, and Loading) tools such as Oracle Warehouse builder and Informatica. This project successfully challenged the long standing thought process that claimed it was impossible to store more than 3 months worth of customer billing information.
• The majority code of the development was done in Visual Basic 5.0 in Window and Motif and Openlook X-Window in workstation, C, later C++, JAVA Object Oriented scheme by using Object Oriented language tools such as RogueWave Tools.h++, DBTools.h, Purify and PureCoverage, Clear Case, Sablime, and ksh script language by interconnecting other systems by CORBA and Connect/Direct communication tools. Codes were implemented by using inter process communication and shared memory scheme - mutli-threading, Sockets, Real Time UNIX based multiprocessor systems.
• Many Other Miscellaneous Project
