What I delivered
- Designed a multi-tenant GraphQL layer generating a dedicated schema on the fly for each organisation from its company token, where GraphQL is static by nature.
- Every tenant gets its own schema, introspectable like a regular API and updated automatically: any developer can plug a dedicated front-end onto their own CRM.
- Ongoing work on platform performance and scalability, plus front-end contributions in React.js.
