9## Tech Stack
10- **Frontend**: React 19, TypeScript, NextJs 15, ShadCN components
11- **Backend**: Nodejs, PostgreSQL, Redis, Rabbitmq
12- **Monorepo**: pnpm workspace with docker composer

14## app Structure

30## Key Principles
31- **Functional components only** (no classes)
32- **Named exports only** (no default exports)
33- **Types over interfaces** (except for extending third-party)
34- **String literals over enums**
35- **No 'any' type allowed**
36- **Event handlers over useEffect** for state updates
