Other work, projects and internships

Lions Head view (2015) I created a Raspberry Pi-based device which automatically takes minutely photographs, collates them into timelapse videos and uploads them to YouTube and other social media (Raspberry Pi, bash, AWS, IFTTT, YouTube API)

Howzit Instant Messenger (2010) I created a web app which was a fully-functional Mxit client, allowing Mxit to be used via a web browser. It provided integration with other social networks and supported Mxit's binary protocol for media transfer (Node, JavaScript, PHP, HTML, CSS)

Snapbill (2010) I worked on an online recurring billing and invoicing web app. I created an abstraction layer over the various payment gateway providers (PHP, Python).

ACI Worldwide (2008) Internship. I created a load and stress-testing framework on top of the existing functional testing framework for the core real-time transaction processor, which was the company's main product. This work included optimising the real-time transaction processor (Grinder, Python, Java, Jython). I created a plugin for Eclipse IDE which provided syntax correction, suggestions and highlighting for the existing proprietary test case specification language (DSL) (Xtext, Java, Eclipse).

Silvaknit (2002) I created the UI front-end and serial port (RS232) interface for converting a punchcard-based textiles factory to a digital and hydraulic solution. This allows the customer to program the knitting machines using a UI rather than punchcards (Visual Basic 6).
