# Telecom-as-a-Service (TaaS) Platform

> **Sovereign, Full-Stack Cellular Connectivity Platform**  
> Built with Go 1.26, Rust 1.94, TypeScript, eBPF, and 5G Core Network Technologies

## Overview

This is a production-ready Telecom-as-a-Service platform that enables developers to programmatically provision and manage cellular connectivity through a clean API. The platform implements 3GPP standards using modern open-source technologies.

**Technology Stack:**
- **Go 1.26**: Core network integration, BSS API, carrier connector
- **Rust 1.94**: eBPF packet gateway, real-time charging engine
- **TypeScript/Next.js**: Developer dashboard and SDK
- **free5GC**: Open-source 5G core network
- **MongoDB**: Subscriber data and authentication
- **Redis**: Real-time credit control
- **eBPF/Aya**: High-performance packet processing

## Quick Start

### Prerequisites

- **Go 1.26+**: [Download](https://go.dev/dl/)
- **Rust 1.94+**: `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`
- **Node.js 22+**: [Download](https://nodejs.org/)
- **pnpm**: `npm install -g pnpm`
- **Docker**: [Install](https://docs.docker.com/get-docker/)
- **MongoDB 7.0+**: [Install](https://www.mongodb.com/docs/manual/installation/)
- **Redis**: `sudo apt-get install redis-server`

### Installation

```bash
# Clone the repository
git clone https://github.com/nutcas3/telecom-platform.git
cd telecom-platform

# Build all components
make all

# Start services (requires separate terminals)
# Terminal 1: API Server
./dist/api-server

# Terminal 2: Carrier Connector
./dist/carrier-connector

# Terminal 3: Charging Engine
./target/release/charging-engine

# Terminal 4: Web Dashboard
cd apps/web-dashboard && pnpm dev
```
