Lead Product Designer

I'm a lead product designer based in London. I design consumer products that people use every day, making complex things feel simple across every platform.

I’m currently building Fiuto.ai, an AI-powered user research tool I designed and built solo. Before that I was Product Design Lead at GitLaw, an AI-native legal platform, and spent 3 years as Lead Product Designer at Samsung Food, helping deliver AI-powered features, transforming design processes, and managing the design system.

My background is rooted in streaming and multi-platform design at DAZN, Discovery, and Massive Interactive, designing native experiences across mobile, web, smart TVs, and connected devices. I’ve also worked on consumer products at Nando’s, VAHA, and EE.

Design process

My process has always been a classic double diamond: a discovery phase where the team agrees on a direction, then iterative design until they sign off on a solution. User research runs through it, end to end.

AI hasn’t collapsed that shape, it’s stretched it. The divergent and convergent phases are still there, but the amplitude is far greater: AI covers ground orders of magnitude wider and faster than a team could on its own. What changes is where the humans sit. Researchers, designers and the product team move to direction, review and resolution: setting the questions, judging what comes back, deciding what to test and what gets tested and delivered.

01Discovery

Discovery

The tech stack and roadmap set the constraints. I research the market around them: competitors, best practices, products built for our ICP. That gives me a handful of directions to put in front of the team, and we pick one to iterate on.

With AI

Most of that scanning now runs on agentic workflows: competitive landscape, user journeys and best practices. I synthesise the output into a direction I can defend. Desk research that took days takes hours, and covers far more ground than I could on my own.

Discovery with coding agents

Case studies on desk research, planning, prototyping and release run with coding agents: one recorded session per workflow, and the decisions that stay with the team.

Design

Once we’ve picked a direction, it goes into rounds of iteration with the team and stakeholders, each one narrowing the open questions until we agree on a solution we can test and deliver.

With AI

The AI coding tool takes on the designer’s function, partly or fully. I’m then the first stakeholder, but team reviews still decide what moves on to test and delivery.

Design with coding agents

Case studies on component and feature design inside the coding agent, from review to code, and where a designer still decides.

03User research

User research

Research runs alongside the process: at each stage there are methods that can resolve the team’s doubts with real user feedback. Where there are none, established patterns can be enough.

With AI

User research shouldn’t be the blocker in an AI-accelerated workflow, but when everything else speeds up and research doesn’t, it can become one. I built fiuto.ai to solve that mismatch as a personal tool. I’ve since built it into a real product.

Work

Recent work

My three most recent roles, each with one case study in depth. They show the process above applied to real products. Earlier roles follow in brief.

Fiuto.ai

Solo founder · Ongoing · AI user research

Fiuto.ai aims to be what I was looking for when searching for a modern research toolkit. It is a product I have designed and built solo out of a personal tool, with advanced insights and generous sharing capacity I could not find anywhere else.

Samsung Food

Samsung Food is a recipe and meal planning app with a large daily audience. I was Lead Product Designer, working on the surfaces people open every day.
