I design B2B software worth building, and ship it with your team

Principal AI product designer. I close the gap between design decision and shipped product — fewer handoffs, faster validation, engineering context built in from the start. They call it the trio: product, design, engineering. Twenty years sitting across all three, founding my own agency alongside engineers and building startups alongside founders — owning strategy, roadmap and validation as much as the design work itself. AI-native product design from validation through delivery, design systems, customer research that changes direction, cross-functional leadership without the overhead of hierarchy. The craft now is keeping speed and quality in the same hand.

Selected work

Chime Labs AI Platform

A Sydney AI startup for trades, backed by 500 Global. An AI receptionist that books the job. I run product end to end.

Smokeball

A twenty-year-old desktop legal product needed a web product for the US market, and a date. I designed the one that shipped.

Singapore Government Work Visa Application

Singapore's first agile-delivered government software. I led design on the work-pass service, from discovery through deployment.

Neo Innovation

Led design and product for Neo Innovation's Singapore office. Lean UX consultancy work across government, global logistics and early-stage startups — including around thirty three-day inceptions where founders found out, cheaply, whether they had a business.

Principles

The operating system behind every engagement.

Evidence before opinion

Research, testing and data settle decisions. Not the loudest voice in the room.

The smallest increment

Ship the smallest thing that proves the point, then build on what survives.

AI supports, it doesn’t lead

It takes the repetitive work. What to build, what to cut and what good looks like stays with people, in a room.

Simplify success, don’t complicate it

Technology should make the outcome easier to reach. If it adds friction, it is not finished.

Recommendation

“Justin is one of the best product designers I’ve ever had the pleasure of working with.”

Mathew Pretel — CPTO, Chime Labs · via LinkedIn

Adoption is the finish line

Not satisfied until your customers are actively using what we built.

The baseline moved

Building got cheap.
Choosing what to build didn’t.

The baseline has moved — everyone ships fast now. What separates the work is knowing which problems are worth solving, and having the craft to make the answer feel obvious. AI didn’t remove the hard part — it moved it. When a feature costs a weekend instead of a quarter, the expensive mistakes happen earlier: the wrong problem, the wrong first cut, the wrong thing to say no to. Judgement is the constraint now, not velocity.

Most of the work is in how people describe a problem — the friction, the motivation, the why behind the solution they think they want. Then deciding what gets built first, and making that core function simple enough to land. Prioritising and designing stop being separate jobs somewhere in there. I work the whole arc: first exposure, onboarding, retention, growth. These eleven are what I’m hired for most often.
