About Ahmed Ragab

I am a results-driven Full-Stack Developer with strong experience building scalable, secure, and production-grade systems using Node.js, React, TypeScript, Django, and modern web technologies. I specialize in designing robust RESTful and GraphQL APIs, complex business workflows, and data-driven applications with a strong focus on security, performance, and reliability.I have delivered multiple real-world systems across different domains, including data management and visualization platforms, financial and financing workflows, incident and case management systems, and real-time applications. My experience includes building admin dashboards, handling Excel-based data ingestion, generating interactive charts and reports, and implementing complex multi-step forms with identity verification, document uploads, and financial calculations.I have hands-on expertise in authentication and security hardening, having implemented advanced auth flows with JWT, OTP verification, email workflows, protected routes, and rate limiting. I actively worked on identifying and fixing critical vulnerabilities such as Account Takeover, OTP bypass, IDOR, SQL Injection, and XXE, ensuring all authentication and authorization decisions are enforced server-side following modern security best practices.My work also includes building multi-channel notification systems (Email, SMS, Push, In-App) with templating, localization, delivery tracking, and user preferences, as well as integrating secure payment gateways (HyperPay) using Django REST Framework. I have experience with real-time systems using WebSockets (Socket.io), location tracking, and event-based updates.On the frontend, I build clean, responsive, and maintainable interfaces using React, Next.js, Tailwind CSS, ShadCN UI, Redux Toolkit, focusing on usability, performance, and seamless backend integration. I enjoy solving complex technical problems, improving system architecture, and collaborating with teams to deliver reliable, secure, and impactful software solutions.
