Sector 7 USA, LLC., Austin, Texas

Sept 2012–Sept 2017

Senior Software Migration Engineer

Responsibilities:

Migration of Customer applications from one platform to another platform. The usual source platform has been HP VAX and ALPHA running HP OPENVMS. The usual destination platform has been LINUX RED HAT and LINUX SUSE.

Customer code included Stock Trading Systems, Telephone Service Systems, Automobile Factory Robot Control Systems, Point of Sale Systems and Librarian Systems. All of these required specific screen updates as necessary for the specific data to be displayed.

Strong working knowledge of creating the necessary API library support for the OPENVMS applications such that the OPENVMS code not only compiles on LINUX but also has the necessary OPENVMS APIs and other OPENVMS symbols readily available. These APIs are written both in C and C++.

Proficient in the creation of C++ programs to perform OPENVMS capabilities such as JOB/PRINT queues, Operations Communication applications, DCL shell for UNIX/LINUX.

Creation of specialized language translation and software tools in order to more customer applications and data from OPENVMS to LINUX. This is needed as application source on OPENVMS does not necessarily follow any coding standards and usually uses OPENVMS extensions that do not easily work on other platforms. Data on OPENVMS is not usually stored in a database, but stored in Keyed Access Files (aka INDEXED) and this file type is not readily available on LINUX. Thus specialized tools are needed in order to get the extended meta data of these files, as well as the data, and are used to create database import file and/or DISAM files on the LINUX systems.

Complete setup of platforms for the migration effort. This includes installation of LINUX and OPENVMS not only on actual servers but on virtual server as well. Setting up network firewalls such that specialized ports are used for access. Setting up SSH access for all to use.

Usage of GIT and CVS to keep code in sync between contracts and versions.

Project management of individual efforts, from both company and customer side, in order to get required efforts not only tested but integrated into the overall customer project.

This effort requires a deep understanding on how OPENVMS APIs work and how to handle coding these same APIs in a LINUX environment.

IBM, Austin, Texas

Sept 2003–Sept 2012

Senior Migration & Consolidation Engineer

Responsibilities:

Migration of customer code from legacy UNIX servers to IBM AIX servers. This included difficult migrations involving C++ where the original source was on a non-ANSI compliant platform and going to AIX. Much of the C++ code needed modification just to compile and additional modification to properly execute as expected.

Consolidation of customer servers in order to have a smaller footprint within datacenters. This requires that all servers be looked at and categorized into various server types that can be either virtualized and/or merged into servers capable of handling the workload.

Creating documentation detailing what servers can be consolidated into fewer servers, what servers can be virtualized, what servers should not be consolidated and what servers should not be virtualized. This also included what servers needed to be LIFT-AND-SHIFT (Physical Move).

Setup of hardware within datacenters around the world. This included installation of various UNIX platform (AIX, SOLARIS, LINUX) in either physical or virtual servers on both DMZ and non-DMZ LANs.

Creation of AIX NMON output compression tool such that as 24 hour NMON output file can be compressed into a little as 1 minute of data. This is specific to allow EXCEL to easily process the data and produce reports. 24 hours of data will have EXCEL using all available memory on a PC and thus crash.

Infrastructure migration of PAM and AD credential servers for customers such that these servers could handle clients in multiple data centers during a migration process.

Use of Puppet 5.0 to upgrade Windows servers prior to being migrated between data centers.

Creation of virtual LINUX servers specific for datacenter moves where physical LINUX servers were being de-commissioned and virtual LINUX servers were needed. This is part of server consolidation where virtualization was required.

Handling customer servers that are not properly configured. This is necessary as applications that use ORACLE and/or SYBASE require specific tuning configurations or the servers will appear to go to sleep while the databases are being synced from memory cache.

Handling trouble tickets that arise.

Handling network issues within datacenter when networking issues were detected.

Project management of various teams in order to get sub-projects completed as specified in the project plans.

Senior Software Migration Engineer

Responsibilities:

Migration of Customer applications from one platform to another platform. The usual source platform has been HP VAX and ALPHA running HP OPENVMS. The usual destination platform has been LINUX RED HAT and LINUX SUSE.

Usage of C, C++, JAVA and BASH Scripting to get customer code not only migrated form OPENVMS to LINUX but to also add capabilities with LINUX libraries such that existing code doe not require unnecessary changes. This includes creating OPENVMS API that work on LINUX and creating additional JAVA JAR files to use the additional LINUX libraries as needed.

Strong working knowledge of creating the necessary API library support for the OPENVMS applications such that the OPENVMS code not only compiles on LINUX but also has the necessary OPENVMS APIs and other OPENVMS symbols readily available.
