Product Designer

I'm Marissa (Mitzi) and I
love designing useful and delightful digital user experiences.


What I enjoy the most about designing is the challenge of using lateral and logical thinking, combined with key insights to create intuitive and engaging digital designs.

Areas of expertise

Customer Experience

I look at how people interact with a business holistically to identify pain-points and opportunities.

Surveys + Interviews

I use these research methods to enable me to gather attitudinal insights during each phase of the design process.

User Testing

I observe user's behaviour to uncover whether there is a need for a suggested product and gather qualitative data.


Using insights collected from market research, industry reports and studies etc. I make key design decisions.


Since my Google Analytics skills are basic I love working closely with Data Analysts to gather important insights.


To organise content and create hierarchy I conduct exercises such as grouping, card sorting and tree testing.


I use both low fidelity sketch prototypes and interactive high fidelity prototypes to present and test websites.

Visual Design

This is important because people judge the quality of a product higher and think it works better when it's attractive.

User Interface Design

I like to follow the 10 usability heuristics for user interface design to ensure I've created the best user experience.

Interaction Design

I create meaningful relationships between people and products by using the most common interaction patterns.


Using either my front-end dev skills in HTML/CSS or a CMS I can build whatever is required from banners to websites.

Usability Testing

I like to setup usability testis to observe whether my design was successful and uncover any unaddressed pain-points.


I love to create non-distracting and light animation to dynamically bring a page to life and improve a user's experience.


I use experimentation to improve UX which in turn has proven to result in an increase in revenue.


Inclusive design that encompases the full range of human diversity is important to me and always a consideration.

What people think

I want to let you know that Vivi and Marissa were incredible today getting art direction across the line for iPhone. These ladies especially Marissa led the entire team all day from very early, managing over 42 pages of assets and having people tugging at them all day and they were so gracious and professional it really needs to be commended from ELT.

As we all know we beat Telstra out the gate, thanks to the design team, this will put us in great stead to give our customers great value and a terrific online experience… well done Marissa...

I had the pleasure of having Marissa in my design team for over 2 years. Marissa is a thoughtful designer who gives every brief careful consideration and has a solid rationale for her approach. Marissa has a delicate touch and her designs are elegant and sophisticated. She always has a digital first approach…
