Writing, design, film, product and software — Sydney

I think meaningful ideas start with understanding.

Nearly four years at MECCA taught me to ask better questions — and notice the problems people had learned to work around.

I follow the thread from first observation through writing, design, film and whatever needs to be built.

The working desk behind VESSEL — containers, sketches, specification drawings and material swatches surrounding the system in development.

Where it started

My part-time job became my favourite part of the week — and the place I learned to pay attention.

Working at MECCA taught me how much you can learn by genuinely listening to people.

I loved asking questions, listening for what someone actually needed and finding the right solution with them. Over time, the same frustrations and workarounds began appearing in completely different conversations.

People were already finding their own workarounds. I started wondering whether there was a better one.

Finding someone else’s story

Neither customer named the problem. The work was finding the story underneath what they said.

Two customers, on two consecutive days, arrived at the same unsolved problem from opposite directions. Neither of them met. I served both.

The first was preparing for three weeks abroad. Weight-conscious and methodical, she wanted her existing routine in travel format and found, brand by brand, that it did not exist. Her SPF was a dropper serum. She rejected supermarket decanting bottles because they leaked and because a squeeze top cannot reproduce a pipette. She left with a set of travel minis that were not the products she uses. What she needed was format-specific refillable containers.

The next day a man came in to replace a cleanser airport security had confiscated in Europe for exceeding the carry-on limit. He could not have told you the capacity of the bottle he lost. What he needed was carry-on compliance communicated on the container itself.

Two customers could have been an anecdote. Over the following months I served the same two behaviours repeatedly: people quietly abandoning the products whose application method could not be reproduced, and people guessing at capacity until something was taken off them. Neither group ever described a problem with travel bottles. Both were adapting their behaviour around one.

The dependency underneath both patterns is the same. A travel routine only survives if the container preserves the way the product is applied, and if carry-on compliance can be verified at a glance. Every existing option failed at least one of those.

That became VESSEL.

VESSEL

Identifying the gap was one thing. Building the answer was another.

VESSEL V1 — PRE-LAUNCH

A hanging travel skincare system with a container matched to each way a product is actually applied.

A real physical product I conceived and designed, developed directly with a manufacturer in China. Physical samples have been manufactured, received, tested and iterated.

Matched refillable containers, decanting tools and an interior mirror complete the system. Carry-on capacities are printed directly onto each container.

VESSEL / Brand storytelling

A product idea, told through a familiar ritual.

Completed master film · 1 min 20

The VESSEL master film, for the travel skincare system I’m developing. It follows a familiar routine from home, through packing and the airport, to a new destination — making the product’s purpose tangible through an everyday story.

I chose to tell the product through a familiar ritual — home, packing, the airport, a new destination — rather than through a feature list.

My role: product concept, campaign brief, visual references and creative direction.

I used ChatGPT and Higgsfield to develop and produce the film, guiding the narrative and refining how the product was represented. AI supported the footage generation and edit; the creative brief began with the problem I wanted VESSEL to solve.

Positioning / the copy decision

Premium 5-pocket organiser

Five containers. Five places.

The first sells a bag. The second describes what happens when you open it.

The positioning named the mechanism rather than only the benefit: preserving how each product is applied. That language is defensible because it depends on a product decision, not a copy decision.

Behind the film

01Protecting the product

The film was assembled from many separate generations, so I kept three sources of authority: the story map owned the story, canonical product references owned VESSEL itself, and action boards owned each shot. Newer takes were not automatically better. Generations that invented a flap or clasp, moved the hygiene pouch to the front, showed the hook while the bag was closed, changed the five-container system or folded the bag impossibly were rejected — however polished they looked. Product accuracy mattered more than novelty.

02One world from separate scenes

Each scene was generated on its own, so continuity had to be directed: the robe at home, the airport clothing, the evening dress, hair, jewellery, the bathroom materials, and where VESSEL was and what state it was in at every moment. At the airport, the closed bag travels clean-front-up with the pouch attached at the rear and no hook showing — takes that confused that geography didn’t tell the intended story and were excluded.

03Choreography first, editing last

The five formats each have their own physical grammar. Fragrance needed a real funnel transfer, then a believable remove, uncap, spray, recap and return; cleanser and serum needed their own reach, use and return. What remained — audio sync, sequencing, a repetitive decant-and-pouch rhythm — was solved by auditing the takes I already had and editing, rather than generating more. The full master was reviewed end to end until story, product accuracy, continuity and pacing all held.

AI expanded what I could execute. What was true, what was wrong and what stayed was mine to decide.

VerifyTesting it against evidence that could disprove it
Interrogating the idea

Building it started with trying to prove myself wrong.

I started using AI less as an answer machine and more as something to argue with. It gave me a fast way to challenge assumptions, expose gaps in my reasoning and test whether the idea still held up when I pushed against it.

I tested the competitive landscape, customer behaviour, positioning and economics against evidence strong enough to change my mind. Sometimes, it did.

The cost model

~AUD $28~AUD $53

My first landed-cost estimate was around AUD $28 a unit. Proper benchmarking put it closer to $53 — and showed I had left fulfilment out of the model entirely. I kept the worse number and rebuilt around it.

My own hypothesis

My core hypothesisRanked fifth

Ranked against the strength of the evidence, the problem VESSEL is built around — products losing the format they are meant to be applied in — came fifth. I left it where the evidence put it.

The market view, financial range and ranked customer problems show where the case is strong — and where it is still only a hypothesis.

Making it

I had never manufactured anything.

No contacts, no introductions, no idea how any of it worked. I started reaching out to manufacturers, learning what questions to ask and getting better at separating someone who could make a bag from someone who could actually make VESSEL.

I narrowed the search to three manufacturers and assessed them against the same requirements. Margaret in Fujian ultimately stood out because she engaged with the specification itself — questioning dimensions, tolerances and construction rather than simply sending back a quote.

The first physical sample

The first time it existed outside a document.

Why the bag was sampled firstOpen

The bag and refillable containers were developed through separate manufacturing paths. I started with the bag so I could test the complete system using off-the-shelf containers — refining the layout, storage and pocket dimensions before committing to custom containers designed precisely to fit them.

Filmed on my phone, unedited — the first time I ever held something I had designed.

Some of it was wrong.

Parts of the sample had been manufactured outside specification. Pocket dimensions were off and some of the test containers didn't fit properly. Physical testing also exposed details that couldn't be fully understood on paper.

So I went back to the specification.

I documented every deviation, photographed the evidence and changed the way tolerances were communicated — separating the dimensions that controlled whether VESSEL actually worked from those where the manufacturer could have more room.

First sample measured against a steel rule for height
First sample — inspection & function testing
Research after the sample

Having something physical gave me better questions to ask.

Once VESSEL was physical, people could respond to something real. I used quick Instagram polls with friends to ask what they packed, how they packed it and what they wanted kept together or separate. Some answers shaped V1; others became questions to carry forward.

What it changed

The first sample made me rethink storage. Rather than making VESSEL bigger, I designed a detachable hygiene pouch: divided storage for toothbrush and toothpaste on one side, and a razor on the other. I put it back to the research group; the directional response informed its inclusion in V1.

Where VESSEL is now

Built to learn from the next version.

Built

V1 developed through specification, sampling, physical testing and iteration.

Now

Refining the system through further sampling, testing and manufacturing development.

Next

Keep testing the premise while V1 is still in sampling, then finalise the bag and hygiene pouch and develop the fitted container set with a specialist supplier.

THE CERTAINTY GAP / SOURCE IT

Similarity isn’t proof.

Two products can look alike without sharing a manufacturing origin. SOURCE IT treats resemblance as a lead, not a conclusion, and keeps confidence and supporting evidence visible.
