We’re building a next-generation communication platform that brings together WhatsApp-style chat, voice & video calling, and integrated email access — all inside one secure and scalable ecosystem.

The goal is to enable users to chat, call, and access mail in one app, available on web and mobile (Android + iOS), with real-time synchronization and cloud-native architecture.

We are looking for experienced full-stack developers or teams who can design and develop this platform from scratch using Java, Spring Boot, Docker, Kubernetes, and a modern frontend (Angular / React + React Native or Flutter).

Voice & video calls using WebRTC
Email integration (IMAP/SMTP + Gmail/Outlook API)
File sharing and media attachments
Push notifications and message status (sent, delivered, read)
Secure authentication (JWT / OAuth 2.0)
Admin dashboard and analytics panel
Cloud-native deployment with CI/CD pipelines
Preferred Tech Stack

Frontend (Web) Angular 16 / React 18
Mobile App React Native / Flutter
Backend Java 21, Spring Boot 3, Spring Security
Realtime / Calls WebRTC, STUN/TURN, Redis Pub/Sub
