chore: organize docs — move 37 files from root into docs/ subfolders
Root now contains only essential files: README.md, CLAUDE.md, CHANGELOG.md, CONTRIBUTING.md Reorganized into: docs/audits/ — all audit reports & checklists (71 files) docs/architecture/ — codebase overview, implementation plan docs/guides/ — auth guide, implementation checklist docs/load-testing/ — k6 load test guides & endpoints docs/security/ — payment & security reviews Also removed 5 untracked debug/investigation files and cleaned up playwright-report/ & test-results/ artifacts.

|
||||
|
||||
## ARCHITECTURE GRADE: A
|
||||
|
||||
### Backend: **EXCELLENT**
|
||||
- Hexagonal architecture consistently applied across all modules
|
||||
- Clean separation: Domain → Application → Infrastructure → Presentation
|
||||
- Module encapsulation enforced via ESLint (no cross-module internal imports)
|
||||
- CQRS pattern for command/query separation
|
||||
- Event-driven architecture with Sentry integration
|
||||
|
||||
### Frontend: **EXCELLENT**
|
||||
- Modern Next.js 15 App Router (React 18)
|
||||
- Proper separation of concerns (pages, components, hooks, stores)
|
||||
- Zustand for lightweight state management
|
||||
- React Query for data fetching
|
||||
- Type-safe forms with React Hook Form + Zod
|
||||
|
||||
### Database: **GOOD**
|
||||
- 21 models covering all business domains
|
||||
- Proper indexing (30+ indexes including compound indexes)
|
||||
- PostGIS integration for geospatial queries
|
||||
- GDPR-compliant soft deletes
|
||||
- ⚠️ Note: 13 migrations in 4 days suggests schema was being refined
|
||||
|
||||
---
|
||||
|
||||
## SECURITY POSTURE: A-
|
||||
|
||||
### ✓ Implemented Controls
|
||||
- **Network:** Helmet CSP, X-Frame-Options, HSTS
|
||||
- **Application:** CSRF double-submit, rate limiting, input sanitization
|
||||
- **Data:** PII field encryption, hashed emails/phones, soft deletes
|
||||
- **Audit:** Admin action logging, user trails
|
||||
- **Auth:** JWT + refresh tokens, OAuth 2.0 (Google, Zalo), bcrypt passwords
|
||||
- **CI/CD:** CodeQL scanning, dependency auditing
|
||||
|
||||
### ⚠️ Recommendations
|
||||
- Add 2FA for admin accounts
|
||||
- Expand penetration testing
|
||||
- Document incident response procedures
|
||||

|
||||
|
||||
## DEPLOYMENT READINESS: B
|
||||
|
||||
**Ready Now:**
|
||||
- ✓ Docker Compose (dev, CI, prod)
|
||||
- ✓ GitHub Actions CI/CD pipelines
|
||||
- ✓ Database migrations (13 deployed)
|
||||
- ✓ Monitoring stack (Prometheus, Grafana, Loki)
|
||||
- ✓ Security scanning (CodeQL, dependency checks)
|
||||
|
||||
**Before Production:**
|
||||
- ⚠️ Load testing at scale
|
||||
- ⚠️ Disaster recovery drill
|
||||
- ⚠️ Security penetration test
|
||||
- ⚠️ Database schema lockdown (halt migrations)
|
||||
- ⚠️ Alert thresholds documentation
|
||||
|
||||
---
|
||||
|
||||
## OPERATIONS: GOOD
|
||||
|
||||
**Monitoring:**
|
||||
- Prometheus metrics collection ✓
|
||||
- Grafana dashboards ✓
|
||||
- Loki log aggregation ✓
|
||||
- Sentry error tracking ✓
|
||||
|
||||
**Missing:**
|
||||
- SLO/SLA targets
|
||||
- Runbooks
|
||||
- On-call playbooks
|
||||
- Log retention policy
|
||||
|
||||
---
|
||||
|
||||
## COMPLIANCE & GOVERNANCE: A-
|
||||
|
||||
**Implemented:**
|
||||
- ✓ Audit logging (AdminAuditLog model)
|
||||
- ✓ GDPR soft deletes (User.deletedAt)
|
||||
- ✓ Field encryption (PII protection)
|
||||
- ✓ Hash fields (email/phone indexed)
|
||||
|
||||
**To Document:**
|
||||
- Data retention policy
|
||||
- Privacy policy & ToS
|
||||
- Data export procedures
|
||||
- Right-to-be-forgotten implementation
|
||||
|
||||
---
|
||||
|
||||
## KEY FINDINGS
|
||||
|
||||
### 💪 STRENGTHS
|
||||
1. **Enterprise Architecture** - Hexagonal DDD pattern properly implemented
|
||||
2. **Type Safety** - Strict TypeScript throughout
|
||||
3. **Security First** - Multiple layers of protection
|
||||
4. **DevOps Ready** - Full automation pipeline
|
||||
5. **Modular Design** - Enforced boundaries between modules
|
||||
6. **Clean Code** - Zero technical debt markers
|
||||
7. **Testing** - 289+ test files
|
||||
|
||||
### ⚠️ AREAS OF CONCERN
|
||||
1. **Schema Stability** - 13 migrations in 4 days (development artifact?)
|
||||
2. **Test Coverage** - 70K LOC with ~0.4% test file ratio (adequate but could improve)
|
||||
3. **Documentation** - README minimal, API examples limited
|
||||
4. **Operational Docs** - Runbooks and playbooks missing
|
||||
5. **Admin Security** - No 2FA mentioned
|
||||
|
||||
### ✅ GREEN FLAGS
|
||||
1. No TODO/FIXME/HACK comments in codebase
|
||||
2. All modules wired into app.module
|
||||
3. Consistent architecture across 16 modules
|
||||
4. Proper separation of concerns
|
||||
5. Environment-based configuration
|
||||
6. Error tracking integrated (Sentry)
|
||||

|
||||
|
||||
## SCALABILITY ASSESSMENT
|
||||
|
||||
**Current Capacity:** ~100K requests/day
|
||||
|
||||
**Bottlenecks to Monitor:**
|
||||
1. PostgreSQL connection pool (PgBouncer 20/200)
|
||||
2. Redis single instance (suitable for caching only)
|
||||
3. Typesense indexing (plan for sharding)
|
||||
4. S3/MinIO upload throughput
|
||||
|
||||
**Recommendations for 1M+ requests/day:**
|
||||
- Database read replicas
|
||||
- Redis cluster
|
||||
- Typesense cluster
|
||||
- CDN for static assets
|
||||
- Queue system for async jobs
|
||||
|
||||
---
|
||||
|
||||
## TEAM CAPABILITY ASSESSMENT
|
||||
|
||||
**This codebase suggests:**
|
||||
- ✓ Experienced TypeScript developers
|
||||
- ✓ Understanding of DDD/hexagonal architecture
|
||||
- ✓ DevOps/platform engineering knowledge
|
||||
- ✓ Security-conscious development
|
||||
- ✓ Testing discipline
|
||||
|
||||
**Recommendation:** Team is well-equipped to maintain and extend this platform.
