Receptor Software

• Independent Consultant overseeing new software development projects for two major financial institutions. Ensuring all customization requirements are being met.

Atlanta, GA

Senior Product Architect

• Added ADABAS, ACI, and CA-Datacom data access to the Ivory Data Hub z/OS Server, to allow ODBC or JDBC access to these mainframe data sources.
• Designed and developed the Advanced Communications Interface (ACI) used to allow execution and cross memory communication to and from spawned address spaces executing in behalf of the Ivory Data Hub Server.
• ACI also allows for communication with CICS regions to execute CICS transactions for the Ivory Data Hub.
• ACI uses the spawned address spaces and CICS transactions to run Natural, COBOL and various user applications without modification.
• 3270 screen definitions can also be mapped as SQL result sets thus allowing JDBC or ODBC client programs to execute 3270 screen applications with no backend program changes.
• Product architect for an off mainframe Node.js / Express framework using PostgreSQL for data federation both on and off the mainframe data sources.
• JQuery, Angular.js, were used in the front-end.

San Francisco, CA

Manager/Senior Software Developer/Product Author

• Product author and developer of Enterprise Data Replicator (EDR). EDR replicates DB2 transactions in a true Peer to Peer multi-node environment.
• EDR deconstructs DB2 log streams into a XML format at a source node and transfers the data via TCP/IP to a target node to be replayed against a target DB2.
• Conflict detection and resolution, compression, LOBs, partitioned objects, data sharing and referential integrity are also handled by EDR.
• A generic user interface using XML was created that works in TSO/ISPF using REXX sockets.
• Usage of the IBM zIIP processors was instrumental in attaining performance rates that gave EDR a competitive edge over other replication solutions.
• EDR also has a Web server component within the mainframe address space to allow the use of a web browser as the user interface for EDR. SAF security was used to manage access to DB2 object resources via the user interfaces.
• Coauthor and designer of a patented technology* to allow the creation of consistent data imaging without a database present.
• The technology uses a combination of DB2 image copies and log data to produce a consistent point in time loadable image of multiple tables.

Sugar Land, TX

Systems Software Developer

• Responsible for development and implementation of the non-relational to relational components of Shadow Direct.
• The key focus is to provide Shadow Direct with a means to allow access and update to non-relational data sources by giving those data sources the “look and feel” of a relational data source.
• Lead architect and developer of the Data Mapping Facility component of Shadow Direct facilitated this non-relational to relational mapping and SQL parsing. The ADABAS Server component of
• Shadow Direct provides a two tier ODBC and JDBC compliant interface to ADABAS C data from the desktop using SQL.
• Other data sources implemented using this technology include VSAM, IMS and sequential data sources.
