Digital Menu Display Module — Zyap OS -- 2

We are looking for an experienced **Full-Stack Developer** to complete, fix, and improve partially developed modules in our existing **Zyap OS POS platform**.

Our previous developer started these modules but left before completion. Some features are incomplete, some are not working correctly, and some require additional development.

Current pending modules include:

* **Advertisement Module**
* **Website Intelligence Module**
* **Display Manager**
* **Display Menu / Digital Menu Screen Module**

Responsibilities:

* Review and understand the existing codebase
* Find bugs, errors, and incomplete functionality
* Fix frontend, backend, API, and database issues
* Complete pending features and modules
* Develop missing functionality where required
* Connect frontend with backend APIs
* Test everything end-to-end
* Ensure new changes do not break existing POS functionality

**Tech Stack:** Python, FastAPI, PostgreSQL, REST APIs, existing frontend, Git/GitHub.

We need someone experienced in **taking over existing projects, debugging another developer’s code, fixing issues, and completing unfinished development**.

This can become a **long-term development opportunity** for the right developer.
