You will get a Secure Encrypted Messaging App with Flutter and WebRTC
Project details
You will get a production-ready secure messaging and calling app built for organizations that cannot rely on WhatsApp or Signal — admin-controlled onboarding, end-to-end encrypted chat, and WebRTC voice/video with frame-level encryption.
I specialize in Flutter cross-platform apps backed by Node.js microservices. This is not a template chat clone. I build zero-trust systems where servers never hold decryption keys, users are provisioned via Smart Links and OTP, and roles (User, Operator, Admin) control who can monitor, call, or manage identities.
My reference work includes ATEM — a tactical encrypted messenger with triple-PIN duress handling, one-way field monitor mode, Twilio PSTN bridging, and a self-hosted Docker deployment. You get clean architecture, real security decisions, and code you can own and deploy — not a demo that falls apart in production.

I hired Farhan Ullah for iOS app deployment, and the experience exceeded my expectations. I was facing multiple technical and compliance-related challenges with App Store submission, but Farhan handled everything with impressive efficiency and expertise. Within just three days, he successfully prepared, submitted, and got my app approved on the App Store. He demonstrated a strong understanding of Apple’s guidelines and ensured that all requirements were met correctly, which made the entire process smooth and stress-free. I highly recommend Farhan Ullah to anyone looking for a reliable and skilled iOS developer, especially for App Store deployment and approval tasks. I would definitely work with him again in the future.
