About Me

Confident and self-motivated professional.


I am a self-motivated professional, I take responsibility for achieving outcomes, meeting targets, collaborating with others, leading by example and devising ways to improve systems and procedures. I demonstrated this in my roles at Capiscum Corporation, Bundaberg Regional Council, PreviousNext and Instaclustr as I was personally responsible for meeting objectives and targets. I would have a number of active projects and had to self manage my time amongst the projects.

Throughout my career I have been involved in all phases of the systems development life cycle, from inception to deployment and maintenance. I have experience doing business analysis and gathering requirements. Then developing and applying new workflows and business logic to business systems to automate and improve business process and functions.

In design and development of systems I use object-oriented principles and design such as:

  • GRASP (General Responsibility Assignment Software Principles)
  • SOLID (Single responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion)
  • Design patterns such as Dependency Injection, Adapter, Decorator, Factory method, etc.

I have given talks and training on these topics, for example I spoke at DrupalGov Canberra 2014 on the topic of object-oriented design and development and how to migrate from procedural to object-oriented modules.

I am a proponent for automated testing and continuous integration and utilize unit and functional testing. I have contributed patches to Mink and I spoke about the future of functional testing in Drupal 8 at DrupalCon Amsterdam 2014.

I have extensive experience working with government clients and stakeholders. In my 9 years working in local government at Bundaberg Regional Council I collaborated with numerous departments and gained experience and knowledge on domains such as:

  • Asset Management
  • Customer Request Management
  • Electronic Document & Records Management
