The story

Role

Software Engineer 2 Frontend

Description

Spinny Insurance is Spinny's car insurance business, covering everything from the pages customers compare and buy policies on to the internal tools the insurance team runs it with. On the customer side, it guides buyers from the insurance home page through listings and product pages to live quotes. Behind the scenes, an Insurance CRM brings agents' leads, calls, WhatsApp conversations, rosters and refunds into one place, so the team can sell, support and service policies from a single tool.

Impact

Led the vendor migration end to end, rebuilding the home, listing and product pages on reusable component systems, which made the journey faster to iterate on and consistent across pages.
Built streaming quotes using Server-Sent Events across the backend and the client, cutting the wait for the first quote by around 10 seconds.
Reduced the insurance home page's server-rendered document from about 450KB to 97KB, a 78% cut, by moving inline illustrations to cacheable images.
Integrated analytics and performance monitoring, so production issues and journey drop-offs now surface on their own instead of through user reports.
Led the development of the Insurance CRM in React, Zustand and shadcn/ui, now used daily by more than 250 agents.
Built role-based access control for the CRM, so each role sees and does only what it should.
