Professional experience

giffgaff · Product Designer

2023 – Present
  • System evolution: Contribute components and usage rules to giffgaff's design system through its brand redesign, extending it with Broadband patterns to reduce design-to-development handoff.
  • AI in the workflow: Use Claude within the design system pipeline (Figma plugin, Storybook, GitHub, Frontify) to write and review component code and Storybook stories, and to check Figma designs against coded components.
  • 0→1 launch: Led end-to-end UX strategy for giffgaff's Full Fibre broadband market entry, driving acquisition conversion to 6% (vs. 4.5% target) within a 3M+ member ecosystem.
  • Service architecture: Designed service logic across three APIs (UPRN/Loqate, VMO2 Booking, SureSwitch) under Ofcom's One Touch Switch regulation, sustaining 95 NPS despite unpredictable third-party dependencies.
  • Retention & trust: Designed a state-aware pre-activation experience, delivery status visibility and self-service rebooking, reducing the 40% pre-install cancellation rate and achieving 91.7% CSAT and 0.2% first-30-day churn (vs. 5% target).
  • Back-office tooling: Contributed to customer account and support agents' back-office dashboards, turning backend data and statuses into clear interfaces.

Lickd · Product Designer

2020 – 2023
  • Design system: Architected and launched Lickd's first centralised Figma design system, migrating from Sketch and eliminating legacy UI debt to improve engineering velocity.
  • Checkout conversion: Led UX/UI for music licensing checkout, lifting premium licence conversion to 43.5% (+10%) and overall conversion to 42.58% (+5%), and cutting claims tickets by 10%.
  • Prioritisation: Ran ICE-framework workshops with Product and Engineering to align design with commercial targets.

HubbleHQ · Product Designer

2019 – 2020
  • Viewing experience: Improved tenant–host viewing flow, reducing host decline rate by 10% and lifting booking conversion from 14% to 18% through iterative research and high-fidelity prototyping.
