# Tech Stack

## 1. Overview
Sekaya leverages a modern, production-ready Laravel ecosystem to deliver a secure, maintainable, and scalable platform. The chosen technologies emphasize rapid development, rich administrative interfaces, strong security controls, and operational resilience.

## 2. Backend
| Component | Technology | Version (Target) | Rationale |
|----------|------------|------------------|-----------|
| Core Framework | Laravel | 12.x | Mature ecosystem, modern architecture (streamlined bootstrap), rapid development |
| Language | PHP | 8.2–8.4 | Performance improvements (JIT), typed properties, enums, attributes |
| ORM | Eloquent | Bundled | Expressive active record, relationships, query builder |
| Admin Panel | FilamentPHP | v3 | Fast CRUD scaffolding, polished UI, extensible resources/forms/tables |
| Real-Time / Interactivity | Livewire | v3 | Server-driven reactive components without heavy JavaScript SPA overhead |
| Task Scheduling | Laravel Scheduler | Built-in | Declarative job & maintenance scheduling |
| Queues | Laravel Queue (Redis / DB / SQS) | Built-in | Asynchronous processing for imports, notifications |
| Caching | Redis (recommended) | 6+ | Session/cache acceleration, queue backend |
| Search (Optional) | Database full-text / external | — | Extensible for advanced search needs |

## 3. Frontend
| Component | Technology | Version | Rationale |
|----------|------------|---------|-----------|
| Styling | Tailwind CSS | v3 | Utility-first design, rapid iteration, responsive/dark mode |
| Interactivity | Alpine.js | Built-in with Livewire | Lightweight progressive enhancements |
| Build Tool | Vite | Modern | Fast dev server, ES module support |
| Rich Text | Filament RichEditor | v3 | Integrated content editing |
| Icons & UI | Filament Components / Heroicons | — | Consistent aesthetics and accessibility |

## 4. Infrastructure & DevOps
| Concern | Technology | Notes |
|---------|-----------|-------|
| Hosting | Containerized (Docker) | Portable across ECS, Kubernetes, or managed PaaS |
| Web Server | Nginx + PHP-FPM | Standard high-performance stack |
| Storage | DigitalOcean Object Storage | Durable object storage, lifecycle policies |
| CDN | DigitalOcean Object Storage | Accelerated global asset delivery |
| Logging / Monitoring | Sentry | Centralized error visibility |
| CI/CD | GitHub Actions | Build, test, deploy automation |

## 5. Security & Access Control
| Area | Technology | Rationale |
|------|-----------|-----------|
| RBAC | Spatie Permissions | Granular role/permission prefixes integrate with Filament |
| Activity Auditing | Spatie Activitylog | Compliance & traceability |
| Authentication | Laravel Breeze / Fortify | Standard secure auth scaffolding |
| Transport Security | TLS (HTTPS) | Mandatory for all external traffic |
| Password Hashing | bcrypt / Argon2 | Strong hashing mechanisms |

## 6. Communications & Notifications
| Channel | Technology | Notes |
|---------|-----------|-------|
| Email | Laravel Mail + chosen provider (SES) | Template-driven notifications |
| SMS | Unifonic SMS Channel | Regional compliance & reliable delivery |
| In-App | Filament Notifications | Real-time user feedback |

## 7. Data & Persistence
| Component | Technology | Rationale |
|----------|------------|-----------|
| Primary Database | DigitalOcean Databases (PostgreSQL) | Managed service, backups, replicas |
| File Storage | DigitalOcean Object Storage | Scalable, secure, versioned |
| Cache / Queue | Redis | High-performance ephemeral data |
| Backup | Automated RDS Snapshots + S3 lifecycle | Disaster recovery readiness |

## 8. Observability & Operations
| Area | Tooling | Benefit |
|------|--------|---------|
| Error Tracking | Sentry | Aggregated stack traces & performance hints |
| Logging | Structured App Logs | Diagnostics & audit correlation |

## 9. Development Workflow
| Stage | Tool | Purpose |
|-------|------|---------|
| Dependency Management | Composer / npm | Package management |
| Code Style | Laravel Pint | Consistent PSR-12 formatting |
| Testing | PHPUnit | Unit & feature test coverage |
| Local Environment | Docker / Laravel Sail | Reproducible dev environment |
| Asset Development | Vite Dev Server | Fast hot-module reload |

## 10. Extensibility & Modularity
- **Service Layer**: Encapsulates business logic for clear testable units.
- **Events/Listeners**: Decoupled side-effects (notifications, indexing).
- **Filament Resources**: Pluggable CRUD modules; new domain areas can be added efficiently.
- **API Readiness**: Easily extendable with Eloquent API Resources for external integrations.

## 11. Rationale Summary
The stack balances developer velocity (Filament, Livewire), operational robustness (Laravel 12 improvements, queues, S3), and long-term scalability (containerization, Redis, modular services). It avoids premature complexity (microservices) while leaving a clear upgrade path.
