Senior Developer / Consultant

Responsibilities:

• Designed and coded a framework to offload tax report generation from Cobol to Java. For a proof of concept pilot project, reverse engineered and converted a 20,000 - line legacy Cobol report program into Java.
• Data to produce the report is being captured in a striped-down Cobol report program and written to a file that is read in Java running under z/OS. IBM Record Generator for Java utility was used to convert Cobol copybooks to Java beans to simplify marshalling data to and from object and serialized representations.
• Java code recreates all Cobol business rules and produces multiple reports previously generated in Cobol.
• Going forward, the client will be able to use the framework for converting any report.
• All work was done under z/OS and Linux, Cobol, Db2, IBM Developer for z Systems (IDz), Eclipse and IBM Record Generator for Java. Bitbucket was used as a repository and Jenkins for continuous integration.

Senior Developer / Consultant

Responsibilities:

• Designed and coded a Java interface between .NET and Cobol applications. It allows data for accounts that are maintained in a .NET application to flow to a legacy Customer Profile application that runs under Micro Focus. The interface consists of 2 daemons, one processing messages to the legacy application and one processing replies from the legacy application.
• Message processing daemon receives MQ XML messages, enriches them with data extracted from local MongoDB database and creates a text message that is sent to the Cobol application via MQ. If required data is not found in MongoDB, it's retrieved from the .Net application via a series of Web Service calls.
• Retrieved data is also stored locally in a MongoDB database to eliminate future Web Service calls.
• The interface consists of approximately 90 Java classes and Interfaces and was coded under Linux using Java EE, WebLogic, MongoDB, Db2, SQL Server, Web Services (SOAP and REST), Eclipse and Git.
• Participated in system modification and migration of a legacy Customer Profile application from IBM Mainframe to Micro Focus Cobol under Windows.
• Designed, coded and implemented a new interface and backend to replace a legacy Tablebase package. Created JIL and set up Autosys job scheduler.
• Converted numerous Db2 Cobol Stored Procedures to native SQL procedures running under Db2 for Linux.
• All work was done under z/OS using Enterprise Cobol, VSAM, CICS, Db2 for z/OZ and Linux, Micro Focus Net Express, Visual Studio, Visual Cobol, Autosys, Perforce and Git / Bitbucket.
