# Developer Hub (Reference: https://docs.iqra.bot/developers)

Welcome to the Developer Hub. Whether you are building a client-side application using our SDKs or deploying the full Open Source platform on your own infrastructure, this is your starting point.

Iqra AI is built on **.NET (C#)**. It is designed as a distributed, multi-region system capable of horizontal scaling.

High-Level Architecture [#high-level-architecture]

The platform consists of four primary services communicating over HTTP and interacting with a shared data layer.

Core Services [#core-services]

| Service            | Technology     | Role                                                                                                                                       |
| :----------------- | :------------- | :----------------------------------------------------------------------------------------------------------------------------------------- |
| **IqraFrontend**   | ASP.NET MVC    | Serves the User and Business Dashboards. Handles client-side API requests and UI rendering.                                                |
| **IqraProxyApp**   | ASP.NET Core   | The **Gateway**. Handles inbound telephony webhooks, route lookups, billing checks, and forwards requests to the correct regional backend. |
| **IqraBackendApp** | ASP.NET Core   | The **Brain**. Handles the real-time conversation logic, audio processing (ingress/egress), and orchestration of LLM/TTS/STT services.     |
| **IqraBackground** | Worker Service | Handles queue cleanup, stale session termination, and asynchronous maintenance tasks.                                                      |

Data Layer [#data-layer]

The platform relies on a specific stack of persistence technologies:

* **MongoDB:** Primary storage for Users, Businesses, Agents, and Logs.
* **Redis:** Hot storage for active sessions, audio buffers, and real-time state.
* **Milvus:** Vector database for RAG (Retrieval Augmented Generation).
* **RustFS / S3:** Object storage for recordings, assets, and cache files.
