Integrate 3 React/tRPC Modules into Existing Dashboard

I am looking for an experienced Full-Stack Developer to integrate three pre-developed modules into my existing Software Project Management Dashboard. I have the complete source package, including React components, tRPC routers, and Drizzle ORM schemas. Crucial Requirement: The integration must be performed without overwriting or damaging any existing data. I am already using the dashboard, and all current entries must remain intact during the database schema update. The Modules to Integrate 1. Navigator: A bookmarks/tile board featuring live iframe previews and server-side online/offline status checking. 2. Budget: Project-level financial tracking featuring utilization bars, expense logging, and drag-and-drop reordering. 3. Team: Team member profiles with assigned-project lists, skills management, and avatar uploads. Technical Stack: The developer must be proficient in the following technologies used in these modules: • Frontend: React 19, TypeScript, Vite, Tailwind CSS 4, and shadcn/ui. • API/Backend: tRPC 11, Express 4, and Node.js. • Database: MySQL/TiDB using Drizzle ORM. • Storage/Auth: S3-compatible object storage and OAuth/Credential-based login. • Testing: Vitest. Key Deliverables & Responsibilities: • Database Migration: Implement the Drizzle ORM schema changes. Note that the Budget module stores data directly on the projects table (budget, spent, etc.) to optimize query paths. • Backend Integration: Set up the tRPC routers for Navigator, Budget, and Users-Team. • Frontend Implementation: Integrate the .tsx page components while maintaining existing state logic, such as the PROJECTS_COLLAPSE_THRESHOLD = 4 constant in the Team module. • Server-Side Logic: Ensure the Navigator status cache (60-second in-memory Map) is correctly implemented to avoid CORS issues. • Testing: Run the existing Vitest suite (94 tests) to ensure a successful, "green" integration. Requirements: • Proven experience with tRPC and Drizzle ORM is mandatory. • Strong understanding of MySQL migrations to ensure zero data loss. • Clean, documented code following the existing directory structure.
