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.
