Here is a chronological listing of the positions I have held since graduation form College. They are in reverse order.
|
|
2/18 - 7/18, Coca-Cola Company, Atlanta GA. (contract)
|
|
Linux Administrator. Develop code for AWS CodeDeploy. Worked with Azure team on conversion from Siteminder to Azure multi factor authentication. This included insulation of Apache proxy servers from AWS CodeDeploy to 13 development, test and production instances. The bash script would retrieve RPM modules via the firewall using yum and git to install the Apache components before httpd startup. The program was able to install, stop, start, status, clear and recover previous installs in any combination and sequence either from CodeDeploy or the command line. |
|
9/15 - 6/17, Georgia Department of Labor, Atlanta GA. (contract)
|
|
Developer/Programmer. Linux Administrator. Develop automation programs for application support of the re-hosted mainframe CICS system. This was a new, large scale, RedHat Linux installation established to re-host 12 CICS regions in 5 domains, prod, qa, dev, qa, training and lab. The first task was to develop perl and ksh programs to convert sequential and VSAM ebcdic data to ascii. Dell provided basic scripts to start/stop re-host components (TPE, BPE, batch node, CICS regions, DataAdvantage . . .), I split them out to perform start/stop/status functions that will perform within wrapper scripts for all domains, all regions and all instances. I then created an environment system for standard re-hosted scripts to operate across all domains/servers yet sensitive to the instance they were running under. I then created a menu driven system of tools to manage the entire system including monitors. An entire re-hosted CICS instance can be started/stopped/statused from a single menu selection. I then built a web dashboard from which all 5 instances could be managed from the single web site. The site is hosted on the dev server and used ssh via expect to manage all domains. |
|
10/14 - 9/15, Macy's, Johns Creek GA. (contract)
|
|
Developer/Programmer. Member of test and validation team for the upcoming release of Macy's PACE (Planning is About the Customer Experience) application. My assignment was to automate the tedious and time consuming process of validating the Teradata database against the master metadata definition Excel spreadsheet it is modeled after. This required the creation of 4 ksh/SQL programs. One to compare CSV files exported from several worksheets of the metadata spreadsheet and compares them with the manually created Teradata format. The second script used SQL to populate the Teradata database with known and randomly generated data. The third validated the Teradata tables with the database load data and the fourth validated the exported outbound flat files against the Teradata tables. These 4 scripts reduce the staff to validate a new release from 4 contractors to a single staff member and validation time from 2 weeks to lass then a day. |
