Over deze dienst

Looking for a high-performance full-stack web app or custom SaaS platform? I am Sami, a Senior Software Engineer specializing in building robust, production-ready web platforms using Next.js, React, Node.js, and MongoDB.


From enterprise digital wallet ecosystems (like KARDZ and CardlySa) to high-speed subscription platforms, I engineer clean, secure, and maintainable systems aligned with modern digital standards.


What I Build & Integrate:


  • Full-Stack Web Apps: Responsive React/Next.js frontends paired with high-performance Node.js backends.
  • SaaS Platforms & Admin Panels: User management, analytics dashboards, and fine-grained RBAC permissions.
  • Payment & Wallet Systems: MyFatoorah gateway integration, automated subscription engines, and Apple/Google Wallet APIs.
  • Real-Time Tech & Cloud Pipelines: Webhooks, Socket.IO, Kafka event streams, and AWS S3 asset management.


Why Work With Me?


  • Production experience architecting ecosystems with published developer tools on pub.dev.
  • Clean, modular codebase ready for scaling and investment.
  • Complete end-to-end delivery: DB architecture, REST APIs, UI, and deployment.
