Lead product designer · Mobile + web

I lead end-to-end product design for complex digital products, turning dense data and difficult workflows into clear, useful experiences. My most recent work includes a mobile app for Football Australia and analytics dashboards for Translink.

01

Australia's first digital identity platform

Role
Design director
Client
Australia Post
Tasks
Led the design, ran workshops, planned the steps, designed the product, brand and system

The problem

Australia Post wanted a safer way for people to prove who they were online. It had to work on phones, on the web and in person, without feeling hard or scary.

What I did

I led the design from the first idea through to the main screens and steps. We spoke to users, worked through the tricky parts, and turned the identity checks into clear steps.

Digital iD gave people a simple way to verify themselves, and gave Australia Post a new trusted digital service.

Mapping software for property planners

Role
Lead designer
Client
PlanSA
Tasks
Led the design, ran workshops, planned the steps, designed the product, brand and system

The problem

South Australia's planning map was powerful, but hard to use. Casual users struggled to find basic property information, while planners still needed the deeper tools.

What I did

We broke the work into clear tasks, reduced the clutter, and made the map easier to scan. The design kept the advanced tools, but made them easier to find when they were needed.

Planning work for cleaning teams

Role
Lead designer
Client
myhome
Tasks
Research, interviews, workshops, site visits, sketches, product design and testing

The problem

myhome ran a busy cleaning business with paper files, a whiteboard and a lot of local knowledge. To franchise, they needed a digital tool that kept the detail of how the business actually worked.

What I did

We spent time with the team, mapped the day-to-day work, and designed a tool for planning jobs, assigning teams and managing vehicles. The aim was to make the work easier without losing what made the business good.

Helping an email agency move faster

Role
Lead designer
Client
Flowstate
Tasks
Research, interviews, workshops, sketches, product design and testing

The problem

Flowstate wanted to grow without adding more people to every job. Campaign reviews were spread across messages, files and comments, so it was easy to miss changes.

What I did

We designed a place for reviewing emails, tracking changes and getting approvals. The work made each campaign easier to follow, and gave the team a clearer way to improve the process over time.

A native sports game built for match day

Role
Lead designer
Client
Ladbrokes
Tasks
Research, workshops, sketches, product design and testing

The problem

Ladbrokes saw a chance to turn live player and fixture data into a free-to-play game for AFL and NRL fans. The idea was simple: pick players, build a squad, and compete for weekly prizes.

What I did

I led the product design and testing across the core game loop, from choosing players to checking results. The final product was built in React Native, with reusable components and a clear mobile interface for match days.

Self-directed work made to test an idea, learn a tool, or see where a question leads.

01 · World Cup 2026 prediction experiments

Designing the Prediction Triangle

I began with a World Cup bracket that gave people direct control over every result, then experimented with weighted models, automatic calibration and results-based forecasting. With each version, more of the prediction moved from the person to the system.

This raised a bigger question: prediction tools do more than estimate what might happen. They also shape who feels responsible when the prediction is wrong.

Agency
Express and test your own beliefs.
Authority
Use evidence that feels defensible.
Uncertainty
Keep more than one future open.
Prediction Triangle mapping six product iterations between agency, authority and uncertainty
Across six iterations, authorship moved from a manual bracket toward system-led forecasting, then returned through Match Lab and composable authority.

Brackets create closure. Models offer some distance: “the system chose” can feel safer than “I chose.” Match Lab became a way to bring the three forces together.

People build a prediction by connecting visible factors. Outside evidence, such as prediction-market probabilities, can be added without silently replacing personal judgement. I think of this as composable authority: people choose which evidence enters the model and how much influence it has.

About

G'day, I'm Evan.

Over 20 years experience leading design teams and as principal designer/lead across government and financial services.

I love building. Anything from electric vehicles to tiny houses on wheels and veggie patches. I've taught myself how to weld, build houses, wire a canopy for solar, garden and carve a spoon. The more AI creeps into my workflow, the more I find myself needing to retreat to the simpler things.

Currently chopping wood for the fire in Daylesford, Victoria where I live with my partner and two sons.
