💬 Secure Real-Time Chat Web App

A browser-based chat application that allows users to communicate instantly without installing anything.

Built to demonstrate scalable real-time architecture while keeping operating costs low and user data protected.

What I focused on

• 🌍 Global access — users can connect from anywhere through standard web browsers
• ⚡ Smooth performance — heavy network processing runs in the background so the UI stays responsive
• 🔐 Privacy-first design — messages are encrypted on the user’s device before being sent
• 💸 Cost-efficient infrastructure — uses public messaging services for transport while keeping private servers hidden and minimal

Why this matters

This design approach is useful for real-time features in games, collaboration tools, and IoT dashboards, where fast message delivery, scalability, and low operational cost are important.
