About this gig

Looking for a secure, WhatsApp-style messaging solution? I will build a professional Full Stack Chat Application with End-to-End Encryption (E2EE) to ensure maximum privacy for your users.


Privacy is no longer optional. I specialize in building "Zero-Knowledge" systems where only the sender and receiver can read the messages, not even the server admin!


Key Features:

  • Real-time Messaging: Powered by WebSockets for instant delivery.
  • High-Level Security: Client-side encryption using AES-256 or Signal Protocol logic.
  • Media Sharing: Securely send images, videos, and documents.
  • Group Chats: Encrypted group communication.
  • Push Notifications: Stay connected even when the app is closed.


Tech Stack: I use Flutter for cross-platform mobile, Node.js/Socket.io for the backend, and Firebase/MongoDB for secure data storage.


Your privacy is my priority. Let's build a secure future together.
