Full-Stack Software Engineer at Freelance who migrated Daftari POS to multi-tenant SaaS with automated isolation tests.

Palestine, State of

Message

At Freelance, I’ve delivered production systems end to end, including multi-tenant SaaS platforms with role-based access and per-tenant data isolation. I migrated Daftari, a live retail POS app, from single-shop to multi-tenant and added nine automated cross-tenant isolation tests.

I’ve deployed Flutter apps with offline-first sync and ASP.NET Core APIs on DigitalOcean. For a production system, I audited 25 files and added query limits and caching to reduce Firestore over-usage.

On contract with Agricultural Relief, I built a web-based system that brought separate employee spreadsheets into one shared database. My projects also include café management, aid distribution, and business-operations automation systems.
