Client work

Live products I contribute to at WhiteWall Digital Solutions.

  • 01Sinan VMS↗Visitor management platform

    Full stack developer · built with the team from scratch

    Built from the ground up with the team as a full stack developer on both frontend and backend. On the Next.js client I shaped the interface, responsive layouts and component patterns. On the NestJS side I contributed to the REST and realtime APIs, role based access control, S3 backed uploads and database migrations. My focus was clean modular code, thoughtful UX and reliable features that streamline guest registration, analytics and day to day operations.

    • NestJS
    • Next.js
    • TypeScript
    • PostgreSQL
    • S3
    • RBAC
  • 02EventPass↗Full stack event engagement platform

    Feature development, refactors and bug fixes on a live product

    Joined an established, live product and contributed across the stack as a developer. I shipped new features, resolved bugs and led module refactors that keep the codebase healthy as it grows. The platform covers attendee registration, badge generation with PDF export, polls, surveys, gamified moments like the spin wheel and duels, realtime interactions over WebSockets and media handling through Cloudinary. The Next.js frontend and Node and Express backend are designed to be modular and migration friendly so each event can be customised quickly.

    • Node.js
    • Express
    • WebSockets
    • Cloudinary
    • PostgreSQL
  • 03EventPass Website↗Marketing site

    Built end to end on the application side

    Built the full marketing site end to end on the application side. I crafted the layout, components, animations and responsive behaviour with Next.js and React, with an emphasis on a fast, SEO friendly and accessible experience. The reusable component system makes it easy to evolve sections, while an API backed contact and RSVP flow turns visits into qualified leads.

    • React
    • SEO
    • Accessibility
  • 04B2B↗Event matchmaking and engagement platform

    Full stack product development across web, backend and realtime systems

    Built a platform connecting companies, visitors, investors and organizers through matchmaking, meeting booking, booth requests, QR check-ins and surveys. The NestJS and MongoDB backend combines JWT authentication, Socket.IO notifications and a dynamic permission system with role, participant type, ownership and resource-level access. I also developed weighted, bidirectional matchmaking, capacity-aware meeting slots, automated reminders and configurable email and in-app delivery.

    • TypeScript
    • JWT
    • Socket.IO

  • 05Gesture Control System↗Touch-free interaction for large displays

    Frontend engineering and real-time computer vision

    Built a browser-based hand gesture control system with Next.js, TypeScript, MUI and MediaPipe WASM. Real-time landmark tracking and gesture recognition let users interact with large-screen displays without a mouse, remote or touchscreen. I reduced inference time by around 40% and added dwell-based selection with visual progress feedback for precise interaction, alongside a bilingual English and Arabic RTL CMS with S3 uploads.

    • MediaPipe
    • MUI
    • WASM
    • AWS S3
  • 06Hawthorn CMS↗Multi-tenant content management system

    Full stack development, architecture and quality engineering

    Built a multi-tenant, role-based CMS with a drag-and-drop page builder, multilingual English and Arabic support, and an RTL-first interface. The system includes cached fine-grained authorization with privilege-escalation prevention, unified audit logging with field-level change detection, and a cross-module trash and restore workflow with retention cleanup across nine MongoDB collections. Added presigned S3 uploads with server fallback, CloudFront media delivery, schema synchronization, serverless-friendly database connections and 169 passing Vitest tests.
