2023 to 2026
Multi-brand design system
Engineering wanted to reuse the old code-only skinning engine. I pushed back and built a proper token-based design system for a new multi-brand app.

Projects
WS Audiology
One of the world’s largest hearing care groups, serving millions of hearing aid users across 10+ brands in over 100 countries.
2024 to 2026
AI assistant
A conversational AI feature for hearing aid apps: contextual help for device, sound, and troubleshooting questions. I led the conversation and UX design with the ML and product teams, validated across three countries.
2025
Privacy & consent system
A compliant, accessible consent architecture built from scratch: four consent types, dependency logic, RTL, and an EAA mandate, under shifting legal requirements.
2023 to 2025
Bluetooth pairing flow
Bluetooth pairing is the user’s first real interaction with the app, and the biggest drop-off point. I designed the full decision-tree flow across iOS and Android: discovery, pairing, error recovery.
2023
Connexx B2B tool facelift
A visual facelift of Signia’s desktop fitting software under a strict no-workflow-change rule. I ran the UK usability sessions and turned the findings into shipped UI for Connexx 10.0.
2023
RTApps Figma library
I moved the WSA RTApps library from Sketch to Figma and rebuilt it natively: atomic structure, auto-layout everywhere, docs in the file. It powered a UX Design Awards 2023 winner.
CARIAD · Volkswagen Group
Volkswagen Group’s automotive software subsidiary, building the unified software platform and in-car App Store across the Group’s eight vehicle brands.
2022 to 2023
B2B App-Store Portals
Getting a third-party app onto a car’s screen meant passing three internal B2B portals across VW Group’s eight brands, none properly designed. As sole designer I owned discovery, IA, the stakeholder journeys, and a hi-fi OEM Admin portal.
Personal Projects
Side projects built outside company work, where I own design, product decisions, and shipping.
2026
A Sudoku hint engine that names the technique instead of giving the answer. No ads. Built solo in React and TypeScript with Claude Code and Cursor.
2026
This portfolio
Designed and built in Cowork with Claude. The brief, the critique, and the decisions were mine; Claude handled the implementation.
2022
PUMA learning platform
A Problem-Based Learning platform linking companies’ real problems to university students. As sole designer at UnB, I redesigned a core module and designed and tested the whole public environment, desktop and mobile.
2020
Personal finance management
A research-led personal-finance app for Brazil’s Caixa, scoped to one job: saving toward goals. Solo, from mining app-store reviews to a hi-fi prototype and two rounds of testing.
About me
I go after the problems where design has to hold a system together: multi-brand design systems, complex mobile products, B2B tools, and human-AI interaction in products. My best work happens when the hard calls are structural, and when the designer is in the room while scope is still being decided.
A team gets a designer who owns the full stack and the judgement behind it: token architecture, component libraries, product discovery, interaction design, accessibility held to WCAG AA, usability testing, and engineering handoff. I direct AI tools like Claude and Cursor from idea to working prototype in hours, and the decisions stay mine. What I bring is systems thinking, cross-functional influence and expertise, and accessible work that ships.
