Key Accomplishments

• Tenant Isolation Architecture: Enforced strict tenant isolation through Prisma-modeled workspace schemas — mapping users, memberships, organizations, and tasks with cascading delete routines that prevent orphaned cross-tenant data.
• Authorization Middleware Layer: Developed Express middleware (authenticateUser, isOrgMember, isOrgOwner) verifying membership rights across 20 APIs to prevent cross-tenant data leaks and unauthorized escalation.
• Invite-Code Onboarding Flow: Designed a unique 8-character workspace invite-code system validating invitations on signup and preventing duplicate organization memberships — enabling frictionless team onboarding.
• Frontend Performance Engineering: Optimized a React SPA with 6 code-split lazy-loaded routes and 12 manual Vite chunks. Managed server state using 3 TanStack Query caching structures for instant UI updates.
• Containerized CI/CD Pipeline: Containerized the full stack with multi-stage Dockerfiles and Docker Compose orchestration, wired to GitHub Actions for automated image builds and push-to-registry on every merge.
