Custom design for code-extended marketplaces.

For Sharetribe founders extending the platform with custom code, I design the marketplace your developer will build — full Figma files, a design system, and prototypes handed off ready for engineering.

Who this is for

Founders moving from idea to execution

This service is for founders who want more than just polished screens — design that connects user needs, product goals and business outcomes.

What you get

Everything your developer needs

Custom design system

Components, tokens, type and colour set up so your marketplace stays coherent as it grows.

Full Figma files

Every screen, state and flow designed in Figma — organised, named, and ready for hand-off.

User flows & journeys

Mapping how people move through your marketplace and identifying friction before any code gets written.

The process

From discovery to ready-to-build

A four-stage engagement that gets us from problem to a buildable design.

01

Discovery

I learn your marketplace, your users and your commercial model. We agree the problems worth solving and what success looks like before any pixels exist.

02

UX strategy

I map user flows, journeys and feature priorities to create a blueprint for your product. By the end of this stage you'll have a clear view of what should be built first and why.

03

Design execution

Starting with wireframes, we refine layouts until they feel intuitive. Then I create polished, professional screens in Figma — every state, every flow, reviewed with you and refined until it's right.

04

Developer hand-off & support

Organised Figma files, written notes on edge cases and behaviour, and ongoing support during the build. Many founders keep me on retainer as the product evolves.

Testimonials

You're in good company

Francis Porter

Fiona came highly recommended from Sharetribe and our vendor, Journey Horizon. She exceeded all expectations with her organisation, skill, and delivery. Her flexibility to work with us as we iterated on design was very accommodating. Besides being a joy to work with, she impressed us with her design sensibilities and UX recommendations. For a startup launching an innovative platform, Fiona was the perfect partner.

To define Fiona as just a designer would be an injustice. She is a holistic online marketplace consultant who delivers high quality designs at lightning speed. Her ability to think through the objectives given by us, plan the entire user workflow, and finding the right solutions through her designs in a collaborative manner swiftly sets her apart from everyone else. We are very happy with the work she has done for InsightGig and would highly recommend Fiona to anyone looking for a professional designer for their online marketplace.

Lauren Cain

If you're seeking a thorough, proactive, and professional designer with excellent communication skills, look no further than Fiona. She played a crucial role in launching my marketplace, offering valuable recommendations that saved me time and money in the long run. Acting as both a guide and designer, Fiona's expertise was invaluable during the startup phase. Despite the time zone difference, our collaboration was seamless, with completed design sections waiting for me in the morning. Fiona grasped my vision and created a design that felt clean and distinctly feminine, perfectly tailored to my target audience. Without hesitation, I would hire Fiona again for future projects. I hesitated to write this recommendation because I'm afraid everyone will want to snatch her up!

My team love working on projects that Fiona is involved in as she has an excellent understanding of Sharetribe and knows how to deliver clear requirements. She has made our development work much easier. Fiona is also great at helping the business owner turn their idea into a working marketplace. In short she is the true definition of a user experience designer.

FAQs

Common questions

How long does a custom design project take?

It depends on scope, but most projects run six to twelve weeks from kick-off to developer hand-off. We'll agree a clear timeline after the discovery call.

What does it cost?

Pricing is project-based and fixed up front, not hourly. After the discovery call I'll send a written proposal with scope and a clear number, so there are no surprises later.

Do you provide developers too, or can you work with mine?

I focus on design — your developer builds it. I'm happy to work directly with your existing developer through the design and build, answering questions and refining as the marketplace comes together.

If you don't have a developer yet, I've worked with several Sharetribe-fluent developers and can introduce you to the right one.

Can you design directly in Sharetribe?

Yes — I can configure and customise Sharetribe websites using the no-code tools in the Console. However, custom designs are created in Figma. This means you can continue to use your Figma designs should you ever decide to move away from Sharetribe, giving you the flexibility to adapt as your product grows.

Do you also do branding?

I can set strong design foundations — colours, typography and components — to give your product a professional feel. For full brand identities, I collaborate with trusted brand partners and can make introductions if needed.

What types of marketplaces have you worked on?

I've been lucky enough to work with founders across a wide range of industries — home improvement, health and fitness, education, consulting, child care, travel, photography, music, food and sustainability, to name a few.

How do you work with clients in different time zones?

From Hawaii to Sydney and everywhere in between, I love working with clients all around the world and I pride myself on being able to work effectively asynchronously.

I use the time difference to my advantage — it works especially well with clients in America. I can work while you're asleep, so when you wake up you'll have a full day to review my designs and send me feedback. The next morning my time, I jump straight into any iterations. If we need to jump on a call, we'll find a time that works for us both.

Once the project is complete, can I work with you again?

Of course. While most clients start working with me at the idea stage, many return further down the line as they build traction and gain valuable feedback from their customers and suppliers. I have a number of long-standing clients who hire me for short-term, ad-hoc projects as and when they need me.
