Hi 👋, I'm Yousseif Nady

Senior Backend Engineer ( PHP | Node.js )

Backend engineer with 5+ years of experience building production systems that scale and hold up under real usage. My core stack is PHP and Laravel, and I care more about how a system performs in production than how it looks in a demo.

  • 🔭 Currently working as a Senior Backend Engineer at Vast Group
  • 🌱 Currently learning Node.js, NestJS, TypeScript, and Docker
  • 💬 Ask me about PHP, Laravel, MySQL, RESTful APIs, and backend architecture for payment systems
  • 📫 Reach me at yousseifnady59@gmail.com
  • 👨‍💻 LinkedIn: yousseif-nady

🎯 Areas of Expertise

  • 💳 Payment & Fintech Systems — built and maintained backend systems for NFC/QR payment platforms, including payment gateway integrations and split-payment handling
  • 🔌 API Integration — designed a common-interface pattern to integrate multiple third-party POS providers safely, without touching core order logic
  • 🗄️ Database Performance — diagnosed and fixed real production bottlenecks (e.g. reducing DB load from a scheduled command using eager loading)
  • 🧱 Clean Architecture & SOLID — refactoring legacy modules for long-term maintainability
  • 👥 Mentorship — leading code reviews focused on SOLID principles to help junior developers grow
