About

Full-stack developer and Computer Information Systems graduate (University of Jordan, 2026), based in Amman. Co-founder of Dirs (dirsapp.com), a live healthtech platform I built end to end: a Node.js/Express API, a React web app, a React Native app and a multi-tenant admin console, with LLM-powered case intake (schema-validated output, timeouts and fallbacks), real-time chat over Socket.io, server-verified in-app purchases, JWT auth with role-based access, and full Arabic/English RTL. I work with AI coding agents like Claude Code every day and review and test what they produce. Side projects: a booking API in ASP.NET Core + SQL Server and one in Laravel + MySQL, both with tests running in CI.
