Subject Matter Expert at Mobinomics
  • South Africa - Cape Town
  • My current job since September 2010

Back with the UniBase Project.

ClearCase Admin,
Test/QA Environment Support
Automation

Due to my extensive experience in the UniBase Project, understanding the system level so well, I am the goto guy when things fall apart.

Automation of deployments: I created a systemv (QDeploy) to deploy to a wide range (env agnostic) applications, including Weblogic, utilising Qt/C++ Shell Scripts and a MariaDB backend. Quite proud of it.

We reviewed other deployment tools like ansible but found that our 'multiple environment with multiple nodes' created a bit of a configuration nightmare.
QDeploy has an easy user interface which makes managing Env-App-Node configuration very easy and all information are stored in the DB.
It also has tracing (node transactions stored in the DB) which makes Change Management (release: artefacts, configuration baselines) a breeze. For example: you can compared the release-baselines between environments to see what changed between releases, what needs to upgrade/downgrade etc. for equivalency.

ClearCase Support Specialist at Altech Isis
  • South Africa - Cape Town
  • September 2004 to August 2008

Mainly tasked with ClearCase administration and pre-production environment support for the UniBase Project. Build/Deploy/Troubleshoot. Supporting a Weblogic/Tomcat C/C++ and Delphi applications.

This is when I created 'ClearGui' which is a Qt/C++ tool to manage ClearCase (proud of it!).

For the Vodacom Project:
HP-FMS (Fraud Managements System, GSM Tech) application support and customisation (in C++);
Oracle OCI (C++) development with some PL/SQL;
Embedded-C development for GSM POS Device.,

I automated test procedures for HP-FMS using shell scripts and reduced test-cycles from 8 hours to seconds. The company was not pleased as they billed by the hour. But I cannot help but improve things.

My 'Odin' alias file: which includes aliases and shell functions to automate everything I could :-)
(This alias file is still being used by UniBase support and development)

Hobbies

  • Philosophy
    Love reading and researching 'Metaphysical Philosophy'. This quest includes archaeology, anthropology, linguistics, history/histrionics, psychology, cosmology, technology and pretty much any peer-reviewed paper published! Phys.org is a great place to find such papers. My curiosity is apparently boundless :-)
  • Computer Programming
    I have a bunch of 'pet projects' written in Qt/C++ doing all kinds of strange things. Love it :-)
  • Playing Musical Instruments
    Guitar, been playing for so long now! Was in a bunch of bands way back, now I do a 'one man band' thing and upload music videos to YouTube. Mostly so my kids and watch listen from far away.
