Introduction

I build full-stack web applications using React and cloud backends — the kind that handle real users, real roles, and real data from day one. My most recent project is CareOS, a clinic management system I designed and shipped solo over six months. It runs on React 19 and Firebase, with role-based access control for admin, doctor, and receptionist roles, multilingual support across English, French, and Arabic (including full RTL layout), automated PDF billing, and a secure staff onboarding flow using Firebase Custom Claims and Vercel serverless functions. It's live, it works, and anyone can click through it. Before that I built a full-stack school management platform on React and Supabase — PostgreSQL schema, row-level security, JWT auth, file management with signed URLs, and real-time data sync across sessions. Both projects were built from scratch, architecture to deployment, by me. I'm comfortable across the full stack: React on the front, Node.js and serverless functions in the middle, Firebase or Supabase on the back, deployed on Vercel. I've shipped RBAC patterns, i18n with RTL, real-time subscriptions, and automated document generation — not as exercises, but as features in deployed products. I'm based in Algeria (UTC+1 — same timezone as Central Europe) and available for remote contract work with European teams. If you're building something and need a developer who can own features end to end, I'm open to a conversation. 📧 [email protected]
