Majd Kalthoum

Fullstack developer in Berlin

Hi, I’m Majd. I build web apps end to end: React and TypeScript in the browser, Node.js and Laravel on the server.

Most recently I built RTM, a real-time messenger with live typing and presence. It’s the first project below.

RTM

A real-time messenger

Direct and group chats that update live, with typing indicators, read receipts, online presence and reactions, all without a page refresh. A Laravel API and WebSocket server sit behind a React 19 and TypeScript app.

  • React 19
  • TypeScript
  • TanStack Query
  • Tailwind v4
  • Laravel
  • Reverb + Echo
  • Redis
  • PostgreSQL
  • Docker
Live siteFrontend codeBackend code
  • Laravel Reverb delivers messages, typing and presence live; Redis holds that short-lived state so it never touches the main database.
  • Group roles with promote, demote and admin-only actions. Members who leave keep read access to the history up to that point.
  • PostgreSQL full-text search across message history, and private, short-lived signed URLs for attachments.
  • Sanctum cookie sessions, Google sign-in and a complete password-reset flow by email.
  • Light and dark themes, keyboard navigation and screen-reader live regions.
  • 128 backend tests with Pest, CI, and zero-downtime automated deploys to Docker Compose on Oracle Cloud.

Designo

A CMS-driven agency website

A seven-page agency site where every page, menu and label is edited in Strapi instead of being hard-coded. Editors build each page from reusable sections.

  • Next.js 15
  • React 19
  • TypeScript
  • SCSS + Bulma
  • Framer Motion
  • Strapi 4
  • SQLite
  • Docker
  • Caddy
  • GitHub Actions

The visual design comes from a Frontend Mentor challenge. The build, CMS setup and deployment are my own.

Live siteFrontend codeBackend code
  • Ten section types, rendered by a single catch-all Next.js route.
  • Pages are static and refresh every two minutes. If the API is down, the last good version stays online.
  • The contact API validates, length-limits and HTML-escapes input, and accepts 5 requests per 15 minutes per IP.
  • Strapi 4 is hardened: a middleware blocks filter queries on admin fields, and unused auth endpoints are closed on every start.
  • A push to master deploys through GitHub Actions and waits for a healthy container. SQLite is backed up daily.
