- A search system allowing users to find products by categories and subcategories.
- A clean, professional user interface without unnecessary complexity or distractions.

Ideal Skills and Experience:
- Proven experience in app development, specifically for Android and iOS.

- Prior work integrating diverse payment gateways.
- Previous experience in developing catalog systems would be a plus.

Thank you for your interest.
