About this gig

I will design and develop a secure, enterprise-grade encrypted communication platform inspired by modern privacy-focused systems such as Signal and Telegram.


This service is intended for enterprises, organizations, startups, and private platforms that require strong cryptography, privacy, and secure messaging architecture.


What I Will Build:

A custom end-to-end encrypted (E2EE) messaging system, designed with modern cryptographic best practices:

  • DiffieHellman / Elliptic-Curve key exchange
  • Double Ratchet algorithm (Signal-style forward secrecy)
  • Per-message encryption keys
  • Forward secrecy & post-compromise security
  • Authenticated encryption (AES-256-GCM or ChaCha20-Poly1305)


Who This Is For:

  • Enterprises needing secure internal communication
  • Organizations requiring encrypted collaboration systems
  • Businesses needing non-compromised messaging and sensitive data infrastructure


Back-end:

  • Node.js / Express.js
  • Secure REST or WebSocket APIs
  • Secure database system (MySQL, PostgreSQL or MongoDB)



Why Choose Me:

  • Strong understanding of modern cryptography
  • Experience with secure system architecture
  • Clean and well commented code

  • Programming language

    • PHP

  • Expertise

    • Algorithms & Data structures
    • Performance
