UX Designer @ Apparel21 

March 2012 - March 2015

Apparel21 makes fashion for the software industry, primarily an ERP, also called Apparel21, and supporting products: POS (point of sale) System, web-based Mailer app and mobile optimised Stock Finder app.

Most of my work at Apparel21 was working on the existing ERP, however I did work on one large green-field project and documented my process here: UX process for 'Product X' 

Safe-D app

For the development of an app as part of my thesis research I was the only UXer on the team. I facilitated design and research, with other members of the team contributing. 


As anyone in tech knows, family will always ask you for help when their computer breaks. When you're a UXer you get that too (especially since older members of the family often don't understand what you do other than "work with computers") but you also get everyone's idea for an app asking for UX advice. The UX doctor - show me an interface and I'll diagnose what's wrong with it when they can't put their finger on why it doesn't look right. Of course, I always say that I don't know the best advice, we need to talk to the intended users to know that, but I enjoy providing the quick fixes that make the interface look "right".

UX skills 


Affinity mapping is the easiest way to deal with large amounts of qualitative data and see the patterns that are emerging . 


I like to make the complex, simple. My thesis research involved displaying complex messages, simply, with visual statistics.

I enjoyed thinking outside the post-it note and coming up with multiple ways to present this information, and, of course, testing this with users to ensure that they understood what the visuals are trying to communicate.

Workshop facilitation

I have experience conducting workshops with various stakeholders and end users to understand varying needs. 


I am a huge advocate of the benefits of wireframes and prototypes. Words often fail when trying to describe design  vision, so I communicate using the best fidelity for the purpose: a sketch on the whiteboard; a scribble using my handy sharpie; low fidelity wireframes; or pixel perfect.

Person Definition

I have used personas in both academic and industry contexts. I introduced personas to Apparel21 after findings broad ideas of the user were not helping us design for them. Personas were created from aggregated discussions and observations with real users. 


Besides my normal day-to-day UX research - usability testing, qualitative and quantitative analysis, concept validation etc -   I have published research as part of my Masters (completed) and PhD (in progress).  

The UX of Insertables - Devices in, through, and underneath the skin 

Everything to do with my current PhD research is on the Insertables Page

It is known that researchers, artists and hobbyists have augmented their bodies in new ways by voluntarily inserting non-medical devices. However, what devices are being used for and why insertable was the mode selected, are not well documented. Prior work documents single case studies or individual participant use. There is a research gap to understand what people are inserting into themselves voluntarily and why? This knowledge will inform future use and design and position insertables as a device mode of choice for users and a legitimate category for hardware manufactures, HCI researchers and interaction designers alike. 

Developing Interactive e-Health Apps for Complex Messages: Leveraging the Safe-D Case Study (Masters Research)

Smartphone devices have become ubiquitous, and with this e-health apps common. However, the efficacies of available e-health apps vary greatly due to lack of behavioural change theory, scientific foundations and healthcare professional involvement in development. My masters research leveraged the Safe-D case study to develop an app, also named Safe-D, to improve vitamin D status in young women, safely, through persuading UV exposure.

Other research

There's no other way to start a UCD process, than researching the user. My research skills from industry and academia include:

  • Traditional observational usability-lab based research

  • Qualitative interviews

  • Surveys

  • Literature reviews

  • Quantitative data analysis from usage logs
