Breathe HR

Joined Breathe, a SaaS HR platform, as its first designer. The design team has since grown to three.

• Designed the majority of the Breathe mobile app, a React Native app that replaced separate native iOS and Android apps, including the dashboard and the calendar and leave booking screens.
• Built the design system from scratch and lead its governance across the web platform and the mobile app.
• Sole designer on four product modules, end to end.
• Introduced Figma, prototyping workflows and Maze for user research and usability testing, alongside the team’s Mixpanel and Pendo usage and funnel analytics.
• Pioneered Cursor and Claude Code for rapid prototyping across the organisation. Won the group-wide AI award twice.

VGDB (Side venture)

A video game database and community cataloguing around 190,000 games. A ground-up rewrite of the We The Players idea in Next.js and Supabase, with no code reused.

• Designed and built the product solo using AI-assisted development with Claude Code.
• Designing a 54-screen React Native companion app, currently in progress.

We The Players

A funded “Letterboxd for games” community platform with a catalogue of 126,000+ games, backed by its founder and a group of angel investors. Closed in 2023.

• Led product, UX, user research, information architecture and brand from concept to launch.
• Ran product management through an agency-built launch and a move to a second agency.

Nexus Mods

Led the end-to-end redesign of Nexus Mods, the world’s largest game modding platform (today nearly 80M members).

• Membership roughly doubled over the same period, from about 8M to about 16M.
• Ran a community survey that drew 25,000+ responses in a single weekend.
• Originated the concepts for Collections and Donation Points, both later built by Nexus Mods and now core to the platform.

ClinIntel (Acquired by Parexel)

Founding member of a SaaS clinical trial forecasting and management platform.

• Owned the UX and UI of the web application from inception.
• Simplified complex pharmaceutical data and workflows into clear, approachable interfaces.
