Strapi v4 to v5 Upgrade -- 2

I am looking for an experienced Strapi developer to upgrade my personal web blog (harrytang.xyz) from Strapi v4 to Strapi v5 and ensure full compatibility across backend and frontend.

Scope of Work
- Upgrade the existing Strapi v4 backend to Strapi v5
- Update and migrate all custom and third-party Strapi extensions/plugins to be fully compatible with v5
- Upgrade the frontend application (NextJS) to correctly consume the new Strapi v5 APIs
- Handle any breaking changes introduced in Strapi v5
- Perform thorough testing (API, integrations, frontend flows) to ensure everything works correctly after the upgrade
