As a freelance Full-Stack Engineer / Contractor, I architect, deploy, and maintain custom software solutions, backend APIs, and cross-platform applications for regional clients. My work includes secure JWT authentication and multi-role access control for financial, educational, and logistics platforms.
For Vally Order, I engineered backend infrastructure for a multi-vendor delivery ecosystem, developing Django REST APIs for Flutter clients and designing a normalized PostgreSQL schema. I deployed the system on a Linux VPS with Nginx reverse proxies.
I also built the Smart School Management System, a multi-role application for web, desktop, and Android, with localized RTL Arabic interfaces and role-based access control. In DermaScan, I used OpenCV with GLCM and HSV feature extraction for offline-first skin-condition tracking.
