Spaceship Game

Immersive landing page for a boutique digital agency — 3D scene work, fluid transitions, and animations that sell the studio's craft at a glance.

Redesigned mobile banking experience for Egypt's largest bank — a clean, modern interface that raised the bar for mobile banking in the region.

React Native frontend paired with a Nest.js backend, built to the security and compliance standards of a top-tier financial institution.

Omnichannel business messaging suite powering 20M+ messages — helping companies manage customer communication across chat, SMS, and automated workflows.

Multi-product build: React dashboards, Angular client apps, and a Node.js backend serving a platform at scale.

Tap-to-share digital business cards for small businesses — fully branded profiles, instant NFC sharing, and a dashboard to manage your digital presence.

Built with React and Next.js, with a frictionless onboarding flow designed for non-technical users.

Rhythm-Dodge-based space flight game built for the Three.js Journey challenge #22 — dodge enemy lasers and fields at speed, with a bespoke collision system that defines levels and game state.
