+# MerchantsOfHope-SupplyANdDemandPortal - Production Readiness TODO
+
+_Last updated: January 2025_
+
+## 🚨 CRITICAL PRODUCTION BLOCKERS
+
+### Database & Schema Issues
+- [ ] **CRITICAL**: Fix `pgcrypto` extension requirement in `backend/src/database/schema.sql#L1` - add `CREATE EXTENSION IF NOT EXISTS pgcrypto;` before schema creation
+- [ ] **CRITICAL**: Ensure database migrations run idempotently on fresh databases
+- [ ] **CRITICAL**: Fix test database connection issues - local Docker tests are failing with timeout errors
+- [ ] **CRITICAL**: Validate that CI and local test environments use identical configurations
+
+### Security & Data Protection
+- [ ] **CRITICAL**: Implement proper RBAC (Role-Based Access Control) in all endpoints
+- [ ] **CRITICAL**: Sanitize resume file paths - never expose `file_path` in API responses
+- [ ] **CRITICAL**: Add input validation and sanitization to prevent SQL injection
+- [ ] **CRITICAL**: Implement proper file upload validation and size limits
+- [ ] **CRITICAL**: Add rate limiting to all API endpoints
+
+### Frontend Production Build
+- [ ] **CRITICAL**: Replace CRA dev server with production build in `frontend/Dockerfile`
+- [ ] **CRITICAL**: Update Coolify deployment to serve prebuilt static assets
+- [ ] **CRITICAL**: Fix Tailwind CSS processing - add `postcss.config.js` with proper configuration
+- [ ] **CRITICAL**: Ensure all frontend routes work in production build
+
+## 🔥 HIGH PRIORITY FIXES
+
+### Test Coverage & Quality
+- [ ] **HIGH**: Increase backend test coverage from 23.57% branches to ≥50%
+  - Current: statements 61.60%, lines 61.95%, branches 23.57%, functions 78.33%
+  - Target: Focus on RBAC/error paths in applications, resumes, and jobs routes
+- [ ] **HIGH**: Increase frontend test coverage from ~19% statements to ≥60%
+  - Add React Testing Library tests for Dashboard, Login/Register, Jobs, Applications
+  - Test AuthContext flows and error states
+- [ ] **HIGH**: Fix local Docker test suite to match CI configuration exactly
+- [ ] **HIGH**: Add integration tests for resume upload/download workflows
+- [ ] **HIGH**: Add end-to-end tests for critical user flows (login, job posting, applying)
+
+### API & Backend Issues
+- [ ] **HIGH**: Fix dashboard metrics wiring in `frontend/src/pages/Dashboard.js#L18-L45`
+  - Fetch candidate totals from `/api/candidates` instead of duplicating `/api/applications` calls
+  - Gate employer/candidate queries by role for accurate, authorized counts
+- [ ] **HIGH**: Implement resume listing functionality in `frontend/src/pages/Resumes.js#L11-L15`
+  - Create candidate-scoped endpoint `/api/resumes/me`
+  - Wire to `useAuth` for candidate ID
+- [ ] **HIGH**: Allow recruiters to create jobs by selecting authorized employers
+  - Update `frontend/src/pages/CreateJob.js#L27-L85`
+  - Fix `backend/src/routes/jobs.js#L141-L214` to validate ownership
+- [ ] **HIGH**: Harden employer and candidate listings for least-privilege access
+  - Add role checks in `backend/src/routes/employers.js#L9-L78`
+  - Redact contact fields for unauthorized roles in `backend/src/routes/candidates.js#L8-L110`
+
+### Infrastructure & DevOps
+- [ ] **HIGH**: Ensure local test suite and CI run identically (Docker-only approach)
+- [ ] **HIGH**: Add global request size limits and structured logging to Express
+- [ ] **HIGH**: Make Jest `globalSetup` resilient when Docker is unavailable
+- [ ] **HIGH**: Add security scans to CI pipeline (npm audit, Trivy)
+- [ ] **HIGH**: Update `.gitignore` to exclude coverage artifacts
+
+## 📋 MEDIUM PRIORITY IMPROVEMENTS
+
+### Code Quality & Architecture
+- [ ] **MEDIUM**: Create shared axios instance with interceptors for auth failures
