Sayfoone Full-Stack VOIP Calling Platform

Sayfone is a full VOIP calling platform where I worked as the full-stack developer, taking the product from concept to a fully working real-time communication system. I started by shaping the UX/UI and building a clean, responsive interface for calling, chat, and contact management. On the backend, I developed the complete VOIP engine using WebRTC, real-time signaling, secure peer connections, and a scalable server setup to handle call routing, messaging, and user sessions. The final result is a smooth, reliable, Skype-style calling experience with fast call setup, stable audio/video quality.
