System Architecture

Modern Enterprise Architecture berbasis Next.js App Router dengan pendekatan full-stack yang scalable, modular, dan maintainable.

Next.js 16 (App Router) → modern React full-stack framework dengan Server Components & Route Handlers
TypeScript → type-safe development untuk meningkatkan reliability aplikasi
Prisma ORM → type-safe database access dengan relational query optimization
PostgreSQL → enterprise relational database yang scalable dan reliable
React Query (TanStack Query) → server state management, caching, dan asynchronous data synchronization
Zod Validation → end-to-end schema validation pada client maupun server
NextAuth Authentication → secure authentication dan session management
Role Based Access Control (RBAC) → granular authorization berdasarkan role pengguna
REST API Architecture → modular API menggunakan Route Handler Next.js
Audit Logging Engine → pencatatan seluruh aktivitas pengguna secara real-time
Payment Gateway Integration (Midtrans) → pembayaran digital dengan webhook verification
QRIS Payment Integration → pembayaran QRIS secara otomatis
PDF Generation Engine → invoice generation berbasis server
Responsive Enterprise Dashboard → modern dashboard untuk desktop maupun mobile
