Every founder’s journey looks different, but these are the four stages I guide you through.
Test your idea before you invest.
I run structured market research and competitor analysis, then deliver a clear Validation Report so you know whether your marketplace or SaaS product is worth building.

With over a decade of experience in UX and product design, I work with founders worldwide to bring complex ideas to life. I’ve designed dozens of marketplaces and SaaS platforms, from early-stage MVPs to products serving thousands of users.
My approach is grounded in clarity and trust. Every project is documented, structured, and designed to make products intuitive for people while staying visible and credible to AI agents.
I’m based in the UK and collaborate with clients across Europe, North America, and beyond. Whether you’re validating an idea, re-platforming, or scaling a live product, I provide the design expertise to help you move forward with confidence.

Designing for both humans and AI agents demands more than visuals. These are the principles I bring to every project.
Over a decade of experience designing two-sided platforms and SaaS products, from MVPs to replatforming projects.
Every stage is documented and easy to follow, from validation reports to Trello boards. You’ll always know exactly where you are in the process.
I go beyond surface visuals. Every design decision ties back to business outcomes, user trust, and long-term scalability.
My work is designed for two audiences. Intuitive and trustworthy for people, and structured so AI agents can parse and recommend it.
Whether you’re validating, scoping, or redesigning, I’ll make your product clear, usable, and trusted.
