I run a very part-time business providing IT services to various clients.
In 2013 and 2014, whilst travelling around Europe, I took on an increased amount of work (equivalent to 15hrs per week), adding significant new features to the 'OnGuard' product, increasing it's saleable value. The client remained very satified with my work, proving my ability to work remotely, as I have only met the client face to face a handfull of times in the last eight years.
Responsibilities:

• Find and engage clients
• Software engineering process, including:
  • Understanding the problem
  • Creation of requirements
  • Design
  • Development
  • Testing
  • Deployment/release
  • Maintenance and Support
• Research of required software/programming language knowledge
• Research of web hosting solutions
• Decision making
• Use effective communication skills
• Time management
• Management of the business side (eg. billing and tax)

'OnGuard' ACEPro - OnGuard Safety Training Pty Ltd
'OnGuard' ACEPro is currently purchased by and used in over 800 secondary schools around Australia to provide Occupational Health and Safety Training and Testing for students and teachers in Design and Technology classes.
In 2003, I began working with Bruce Lewis of OnGuard Safety Training to develop the current 'OnGuard' ACEPro product. It is an ASP website written in VBScript running on IIS5 and 6 under MS Windows 2000, XP and 2003. The backend database is an MS Access database. This configuration was distributed and deployed locally at all schools.
Over the first nine years we evolved the product through four major versions and tens of minor updates, often integrating new features as suggested by clients. It went from a customer deployed solution with an installer and remote database upgrades to a Software as a Service solution with one server but 1500 MS Access databases.
In the last three years the client has seen the value in migrating to a single database with a new front end implementation in Python and Django. We are still working through the front end migration process with old VBScript on a Windows and new Python/Django on a Linux server accessing two complementary PostgreSQL servers. I also perform system administration on these servers for ITE Services as well as the standard development and support roles.
The range of OnGuard products have been so successful that OnGuard Safety Training are currently looking to expand into other OH&S markets and also overseas with considerable interest from the Chinese market.

www.buickcarclubaustralia.com - Buick Car Club of Australia (QLD)
In 2006, I developed and configured a Seagull Framework based website to allow content management of the website by members of the car club.
I also researched and organised a PHP and MySQL hosting solution that served the needs of the framework and the club.

Face2Face Zimbra - Peter Schwenke
In 2006, I developed a KickStart Linux CD to install a custom extension of Zimbra onto a blank PC. This involved first automating the installation of Fedora Core 4, then adding the custom Zimbra installation and finally configuring it as part of the KickStart installation.

The Environmental Resources Information Network (ERIN) is a group of sections within DSEWPaC with the purpose of providing data analysis and spatial data integration services to the department and the general public. The Landscape Analysis and Ecology Section (LAES) provides mapping services for the 2000 odd threatened and endangered species and ecological communities listed under the Environment Protection and Biodiversity Conservation (EPBC) Act as well as providing vegetation mapping for use with the department and released as the National Vegetation Information System (NVIS) to the general public.
One of the primary tasks of my job was to I take on and complete an existing project, the Species Observations Database. It was a Java based web application that allowed non-programmers to read Species Observations data from many state, federal and non-government sources in many formats and import and translate into a unified relational database (using DarwinCore field definitions). I first worked with the external developer of the application to fix some bugs and later took on the development work myself to finalise and deploy the system and successfully loaded all of the existing data we had from all of our sources in - about 36 million records in over 20 different formats.
Technical skills employed:

• Java
• Python
• Apache Tomcat
• Oracle 10g
• SQL
• Knowledge and handling of various large text (1GB+) and database source data formats (CSV, MS Access, Comma delimited text, Excel, Oracle Dumps, Shapefiles, ArcGIS File Geodatabases)

Another of my primary tasks was to automate basic distribution mapping to find new observations since a distribution map had been completed, perform various error checks on them and then extend the distribution map to include tentative "maybe" regions. This involved significant interaction with ArcGIS from a Python application to load points, select points outside the existing distribution, detect outliers based on calculations against both the current distribution and the existing points, add new regions to the existing distribution map and replace the old one. At the time I left it was still being fine tuned but was producing very acceptable results.
Technical skills employed:

• Python
• ArcGIS both using ArcMap and via the Python packages
• Oracle 10g

I also wrote and maintained various other small GUI programs in Python to help automate some of the many manual processes that the mappers would go through, such as several tools to perform extracts for regular but adhoc data requests.
A number of colleagues within the ERIN group also wrote their own Python scripts, although none of them were trained programmers, so I provided Python and development support and training on a semi-regular basis.

Department of Environment/Department of Climate Change and Energy Efficiency, National Solar Schools Program
May, 2008 - October, 2008 and July, 2009 - September, 2011
The National Solar Schools Program provides grants for installing energy efficiency equipment in schools.
Originally, under tight time pressure, I developed the requested MS Access application to track and approve grant applications and to manage the projects. The partially completed application went live in the first week of July soon after the start of the program on the 1st of July, 2008. From July through to October I continued to develop the application to handle the later parts of the program. I then returned in July, 2009 to convert the back end database from MS Access to Oracle, perform some maintenance tasks and add newly required functionality.
At the start of 2010, it became clear that this application was not going to be replaced by a department wide tool as per the original plan, so we began designing a Python/Django based application. This application will replace 10 individual components that together comprised the entire program management system.
We have currently developed the new application form along with a sophisticated set of statistical calculations to rank applications as the program has now become a competitive grants program. Now that the functionality required for the current funding round is completed, I am re-implementing components of the old system such as the registration form and migrating old data into the new, more robust schema.
As part of Machinery of Government changes that moved our branch into the Department of Climate Change and Energy Efficiency, I was required to assist in transitioning our systems to the new infrastructure and, most importantly, setup and configure a set of dev/test/prod servers to host our systems on.
A very satisfied client.
Responsibilities:

• Manage the project (including one additional developer at times)
• Gather and define system requirements
• Design the solution
• Implement the solution
• Run ad-hoc queries as required
• Setup a dev/test/prod environment to host our application
• Transition our systems from DEWHA to DCCEE

Additional responsibilities before the re-platform:

• Integrate with the Grants Register website (Oracle 10g)
• Import and update GreenVouchers data (Excel spreadsheet), PvRP data (MS Access) and DEEWR data (Excel spreadsheet)
• Import claim form (Adobe SmartForms/xml/csv) and interim claim form (Excel spreadsheet)
• Work with other stakeholders for system integration: SRA IT, GV team, PvRP team, Environment & Business Information Strategies Section
• Facilitate integration into Clarity for when it comes online
• Convert the MS Access back end to Oracle 10g

Technical skills employed:

• Python
• Django
• Linux System Administration (Apache/mod_wsgi, configuring and compiling packages)

Responsibilities:

• Oracle schema design and implementation
• MS Access consulting

Technical skills employed:

• Oracle 10g
• MS Access Forms, Reports and SQL

May, 2010 - June, 2010
DaIMS develop and support a number of systems used to administer the environmental legislation (particularly the Environment Protection and Biodiversity Conservation Act) that the Approvals and Wildlife Division are responsible for.
I was required to build a custom Django widget that provided an efficient dynamic search facility through several hundred thousand taxon names using jQuery. I was then also required to integrate this into a dynamically generated form.
Additionally, I was required to develop a html scraper that extracted public notices posted by a legacy system that is no longer understood and scheduled to be de-commissioned. As systems are replaced, this html scraper will allow us to verify that no new notices are being generated from somewhere we don't realise.
Responsibilities:

• Develop a custom AJAX based widget to search through taxon names
• Develop a html scraper to extract data from an obsolete system

Technical skills employed:

• Python
• Django
• JQuery
• PostgreSQL

Department of Environment, Caring For Our Country Program
April, 2010 - May, 2010
The Caring For Our Country Program provides funding to various communities and organisations to better conserve and manage Australia's natural resources.
Under extremely tight time pressure, I developed scripts to extract, transform and load the data collected as part of the application process into an MS Access database. This allowed the client to run queries on the data to answer questions coming from up the chain. I then began implementing a user interface to allow the assessment panels to allocate scores for different criteria depending on which of the 16 grants the applicant was applying for. I also implemented some initial score calculations for criteria that were numerically based. Finally, I implemented the calculations to combine the scores, rank the applications within their jurisdiction and distinguish the applications that were high enough to get funding.
Responsibilities:

• Design the solution
• Implement the solution
• Extract, transform, load data from the application form schema

Technical skills employed:

• MS Access Forms, Reports and SQL
• VBA
• Excel
• Oracle 10g
• Python

Centrelink, Staff Assisted Claims
August, 2009 - March, 2010
The Staff Assisted Claims application is used by Centrelink staff to create approximately 70,000 new claims for customers every month.
A large component of this application is running on seven Windows machines each providing CORBA accessible functions. I am required to re-platform this component onto the SOE midrange environment running on Solaris. A previous attempt resulted in CPU and IO bottlenecks on the production systems starving all applications of processing power. Therefore I am required to analyse the cause and implement a solution to allow the component to run efficiently on the SOE platform.
Responsibilities:

• Analyse the cause of poor performance
• Design and implement a solution

Centrelink, Local Activities Database
February, 2009 - June, 2009
The Local Activities Database lists organisations and their activities that Centrelink customers may participate in to meet their requirements to receive a payment.
I was required to re-write the application from a ColdFusion web application into a J2EE web application as ColdFusion was no longer supported. No documentation was available so I relied on the ColdFusion code as the specifications. In an effort to consolidate two similar applications, I was required to integrate the application with another previously developed application (ServiceFinder). I was therefore required to migrate the current data into the ServiceFinder schema. I also produced a technical specification for the application.
Responsibilities:

• Reverse engineer the ColdFusion code and produce a technical specification
• Implement the solution and integrate it into the ServiceFinder application
• Migrate the Local Activities Data into the ServiceFinder schema

Technical skills employed:

• Java/J2EE/EJB3
