Within Agile software development model, I worked as a Java developer of the scrum team, develop and implement the Type and Attribute management in the PTC Windchill J2EE application server system. The Type and Attribute management manages the type definitions and attribute definitions for all business objects in PTC Windchill PDM software. All those implementations were completed on test-driven development mode. The new features were tested by automatic tests, e.g. Junit test, Junit integration tests, in Jenkins integration server. Based on Model-View-Controller(MVC) developing pattern, implement the server side's type and attribute management system with Java program. Use the Rose data modeling tool to create the type and attribute model, and persist this model data into database by Windchill JDBC application API. Developed server side view/cache mechanism to keep the model data in the memory cache. Based on MVC pattern, develop and implement the attribute enumeration management with data model, cache and view mechanism in the Windchill J2EE application server. Develop and implement XML exporter/importer to export/import the type and attribute definitions by XML files with Java program. Develop and implement external enumeration provider to enhance the enumeration management. Develop and implement type and attribute manager service API for type manager client UI. Develop and implement attribute column tool to enable dynamic to add business object data model's attribute with Java program. Develop and implement attribute value handler to enable export/import business object's attribute value by XML file with Java program. Develop and implement the security label configuration management with Java Dom XML parser to parse the security label with Java program.
Worked as a key member of the Extended Data Access group to design, develop and support the cryptography security system on Unisys mainframe. Served as the major programmer in the performance applications and other projects. Designed a JCE provider on ClearPath mainframe system. This JCE (Java Cryptography Extension) is implemented by Java program and Java Native Interface (JNI). It supports the major cryptography algorithms including AES, Triple DES, DES and MD5. Implemented a cipher command-line program with this JCE provider to enable ClearPath mainframe to encrypt and decrypt the files/elements on its system. Designed the Cipher API Windows Test Tool. This test tool is implemented by Visual C++ and Microsoft CryptoAPI. With this tool to test and verify, the Cipher API products on the Unisys mainframe are proved by NIST to meet its Cryptography standards requirement. Designed and completed a basic mode Cipher API subsystem. This subsystem enables ClearPath system's legacy languages COBOL, FORTRAN, PLUS and MASM to support major cryptography algorithms. Software Engineer 4 Worked as a major member of System Control group to design, develop and implement several applications to support ClearPath OS system and Unisys VOD (Video On Demand) projects. Implemented Event Table Reporting program to enhance the functionality of the ClearPath IO Arbitrary Device Interface. Completed new statistic functions for the Emulated IO Processor Debugger. This debugger is implemented by Visual C++ to simulate ClearPath IO processor on Windows system. I got one of Unisys Patent Application Invention Award for this product with other coworkers. Designed a simulator program to simulate the Set Top Control Command Protocol major functions of VOD on Windows system. Implemented a parser to parse RTSP (Real Time Streaming Protocol) into the VOD command to start video stream for a VOD project. Software Engineer 5 (Entry level Engineer) develop and implement Light Streaming Control protocol for the Time Warner VOD Alpha System. This protocol is used to implement the PLAY, STOP, PAUSE, FF and REW's stream commands from TV set box to VOD server. This implementation is completed by TCP/IP connection, 2200 TIP transaction C program and RDMS SQL database.
Drove continual improvement to system architecture by refactoring old legacy code.
