Work
Four case studies and a note. Each one starts with the problem, then the decisions that shaped the work.
Recharge.com, now part of Coda · Shipped [CONFIRM]
One platform for 6 sites and 5 apps
Recharge.com sells prepaid codes in 179 countries. I led design on the full redesign and rebuild: a design system, browse and product pages that answer what, where and how, and a checkout that ends with the code on screen. 33% conversion lift.
Coda · Password-protected
Four internal tools, one admin
Customer service at Coda supports eight storefronts with four internal tools. I led design on one admin that replaces them, framed the problem for stakeholders, and prototyped it in working React so agents could test it early.
Shedwool · Shipped
Four roles, one schedule
Shedwool schedules shifts for food tech, e-commerce and local businesses. I led the complete redesign of its dashboard and app around four roles, then added a seven-step setup wizard after launch, when setup turned out to be the biggest complaint.
Nina.care · [CONFIRM: Shipped]
Trust without a long sign-up
Nina.care connects families with nannies, babysitters and au pairs. I redesigned caregiver onboarding into short themed steps and rebuilt booking around shifts. Onboarding completion rose 31% [VERIFY]. Both sides had to trust a stranger first.
