Now on
Most recently I designed and built Fiuto.ai, an end-to-end user research tool for small teams with no research experience.
Paste a link to your product and Fiuto builds the study, runs it with AI respondents and real people, and turns what they say into findings you can share. It works in the browser or from a coding agent like Claude Code or Cursor.
Before that I was Product Design Lead at GitLaw, an AI-native legal platform, and spent three years as Staff Product Designer at Samsung Food, shipping AI-powered features, reshaping the design process and running the design system.
How I work
I start with a discovery phase, mapping the problem space with the team to agree on a direction, followed by rounds of iterative design refinement that end in a solution ready for delivery. User research runs through it end to end.
-
I map the problem space using research
Starting from the product roadmap and tech stack, finding out what users are saying, and looking at how competitors and products in adjacent sectors handle similar problems. I synthesise this research into a set of threads to review in team workshops and on boards.
-
I agree on a direction with the team
Running ideation workshops to turn that research into strategically valuable ideas, which are then concept tested with real users. The best concepts are reviewed with the team and move forward as the agreed direction into the iterative design stage.
-
I iterate on user journeys and designs
Running multiple rounds of iterative design, each with several solution variants and daily cross-functional squad reviews, until they're ready for review with the wider team. Finally, I run usability tests with real users before moving designs into the build stage.
-
I build components as in-repo stories
Once designs are signed off, I build product-ready components, shells and pages as stories in the front-end repository, using Storybook, Ladle or a custom story setup. These are then built into production code and live tested with users.
Cases
A few recent case studies, across consumer products and AI-native tools.
Tailored meal plan
How I worked through the design process to move from an empty planner to a generated weekly plan.
Share panel redesign
How I use a set of custom skills to redesign complex features inside the coding agent, without Figma.
Figma to code
How I connected GitLaw's Figma library and code in both directions, with Storybook as the source of truth.
Recipe AI
How I started integrating generative AI into native, user facing app features.
Career
I've worked across broadcast and streaming, telecoms, automotive, fashion, food, fitness and legal tech. I've done that at agencies, in-house and at startups, including my own.

Fiuto.ai
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.
Case studies

- Onboarding prototypeHow I prototype a whole user journey in the product's own components.
- Visual QA with agentsHow I review a delivered feature with ten agents testing it in real browsers.
- Admin components redesignHow I design and build shared admin components in one coding session, with no Figma handoff.
- Study sharing handoffHow I turn an approved mockup into real components, with states, mobile and both themes.
- Study sharing buildHow I run planning, implementation and checks as one pipeline, and settle the decisions the agent hands back.
- Study sharing releaseHow I take a feature from staging to production.
- Share panel redesignHow I use a set of custom skills to redesign complex features inside the coding agent, without Figma.
- Onboarding build reviewHow I review a built onboarding flow against its prototype and send each fix back.
- Illustrations and animationHow I place illustration and animation on a working screen in minutes, by asking the coding agent.
