Better systems for a circular economy.

- Improved global state and real-time synchronization with TanStack Query.
- Worked on REST and GraphQL integrations and secure, end-to-end data flow.
What came out of it
Improved Core Web Vitals by 35%, reduced API overhead by 60%, and increased development velocity by 30% through shared interface and data foundations.
