- We led frontend delivery and collaborated across product, design and platform engineering.
The problem
Heycar needed to evolve a large automotive marketplace without slowing frequent product releases or compromising the search, discovery and enquiry journeys its customers relied on.
The approach
We delivered major features across the Next.js experience and its GraphQL, Node.js and Express services. We introduced safer feature rollouts and A/B testing with Flagr, improved client-side state with Jotai, and protected critical journeys with Cypress end-to-end coverage while working in a Kanban product team.
The outcome
We helped keep a complex marketplace moving from discovery to production with clearer delivery scope, earlier risk identification and controlled releases. The resulting platform was easier to evolve, test and optimise for performance and search visibility.
Delivery highlights
- Delivered customer-facing marketplace features across a large Next.js application.
- Worked through GraphQL, Node.js and Express service complexity to keep frontend contracts clear.
- Used Flagr experiments and Cypress journey coverage to make major releases safer.
- Improved client-side performance and search visibility while evolving state management with Jotai.
