I'm Iosif Peterfi, 15+ years delivering enterprise web and CMS projects across Europe, focused on reliable, scalable outcomes. This is my speciality: turning ambitious private collaboration goals into fast, on-premise apps that feel like consumer tools while staying fully under your control. You're building a private, business-grade iOS chat app that runs on your own servers, with real-time 1-to-1 and group chats, file sharing, and integrated voice and video calls, all secured with TLS and deployable via Docker or a simple install script. Your needs map to a complete package: a native Swift iOS client that supports push notifications, works on the latest two iOS versions, and a self-contained backend with clear install and config instructions, plus a concise hand-off for your in-house team. I'll deliver a polished app with a signed build for testing, a self-hosted backend stack, and setup docs, all aimed at fast onboarding, predictable performance, and minimal maintenance burden. The plan reduces risk by keeping everything in your control, validating performance against your latency targets, and removing reliance on external services after configuration. Last year I helped a manufacturing firm deploy an on-prem private chat and file tool; in testing they hit under 200 ms message latency and reliable calls, with secure file sharing and no cloud traffic. Happy to discuss scope alignment. Let's chat - I can walk you through my approach in 15 minutes.

Hi, I can build a fast, business grade iOS chat application that runs entirely on your own servers with no third party dependency. My approach focuses on low latency messaging, clean architecture, and reliable real time communication. The app will be developed in Swift with a modern architecture and will support one to one chats, group chats, file sharing, and integrated voice and video calls using WebRTC. The backend will use WebSocket based communication for instant message delivery, with Redis for performance and PostgreSQL for storage. All services will be fully containerized using Docker, including messaging, media relay, and database, so deployment on your Linux server is simple and controlled. TLS encryption will secure all communication. I have experience building real time systems and can deliver a scalable, maintainable solution with full documentation and deployment support. Ready to start immediately.

Hello Sir, this project aligns perfectly with my experience building real-time, self-hosted communication platforms with full control over infrastructure. I will develop a native iOS app in Swift (SwiftUI) paired with a Dockerized backend (Node.js/NestJS + WebSocket + WebRTC) for fast and reliable messaging and calls. The system will support 1–1 chats, group chats, file sharing, and voice/video calls, all running entirely on your own server. For calls, I’ll integrate WebRTC with self-hosted STUN/TURN (Coturn) to ensure smooth performance on both Wi-Fi and cellular. I can setup janus or livekit on your server for this application smooth functioning. Push notifications will be configured to work with your server, avoiding dependency on third-party services beyond Apple’s required APNs. The architecture will be clean, scalable, and well-documented, so your in-house team can easily maintain and extend it. Everything will be optimized to meet your latency targets (<300ms chat, <800ms calls). You’ll receive full iOS source code, backend containers, setup scripts, and a testable build. I’ll also provide a handover session to walk your team through deployment and architecture. Timeline: 2-3 weeks for complete delivery. I’m confident I can deliver a fast, secure, and fully self-hosted solution tailored to your needs. Best Regards Jitendra Sharma

Hi there, You’re absolutely in the RIGHT PLACE. I’ve delivered SIMILAR PROJECTS multiple times and know EXACTLY how to execute this efficiently and correctly from day one. To lock down the SCOPE, TIMELINE, AND PRICING, I’ll need to ask you a few key questions. Unfortunately, Freelancer’s 1500 CHARACTER LIMIT doesn’t allow me to break everything down properly here. Let’s jump on CHAT so I can show you my PROVEN PAST WORK, walk you through the REAL RESULTS I’ve delivered, and outline a CLEAR ACTION PLAN for your project. You’ll immediately see why my approach is DIFFERENT and EFFECTIVE. If you’re serious about getting this done RIGHT, I’m ready to move forward. Looking forward to CONNECTING and WINNING TOGETHER. Cheers, Mayank Sahu

@syedrehan123

Hi there, I can build this completely private, on-premise iOS chat platform. Avoiding 3rd-party SaaS is the best move for data sovereignty, and I can deliver the sub-300ms text and sub-800ms WebRTC call latency you require, running entirely on your own infrastructure. My Technical Approach: Backend: A Node.js/WebSockets signaling server paired with an open-source WebRTC media server (like Coturn for STUN/TURN). I will package everything into clean Docker containers with a simple docker-compose setup for your Linux environment. iOS App: A modern, native SwiftUI application. I will implement native WebRTC frameworks for optimized media performance and battery life, plus a custom push notification gateway to route alerts securely to APNs. Milestone Plan (6 Weeks to MVP): Week 1-2: Dockerized Backend, Database Setup, & Core WebSockets. Week 3-4: SwiftUI Frontend (1-on-1, Groups, File Uploads). Week 5: WebRTC Video/Voice Integration & Push Gateway. Week 6: Local/Cellular Latency Testing, Documentation, & Hand-off Call. As a Full-Stack Engineer, I specialize in containerized backends and mobile development without vendor lock-in. My code is always cleanly documented for in-house teams. Are you planning to deploy this on a specific Linux distribution (like Ubuntu)? Let's chat. Best, Syed M. Rehan

@alizain721

Keeping your team chat completely behind your own firewall is exactly the kind of problem I enjoy solving; I recently delivered a self-hosted Slack-like iOS app for a small fintech that needed the same guarantees. The best thing about me is I’ve worked on a very similar project recently. I built a native Swift iOS client, Dockerized backend services (message broker, REST API, PostgreSQL), and a WebRTC media stack with a TURN/relay so voice and video stayed on-premise. That project included file uploads, push via a private gateway, and sub-300 ms text latency on our tests. What I understand: users sign in, open 1-to-1 or group threads, send files, and start calls; backend is WebSocket-based messaging, media relay via mediasoup/Janus + TURN, TLS transport, APNs for pushes, all deployed with Docker and an install script. I can save time because I’ve already integrated these pieces end-to-end. Two quick questions: do you need SSO/LDAP or just username/password? What rough concurrent user count should the server handle initially? If that sounds good, let’s chat or hop on a quick call to align scope and timeline (I estimate 6–8 weeks for full delivery). Regards Ali Zain!!

@Vetrivelan007

Hi, I understand you’re looking for a fully self-hosted team chat solution with real-time messaging, file sharing, and voice/video capabilities. Building everything from scratch at this level (especially WebRTC and real-time infra) can become complex and time-consuming. Instead, I’d approach this in a practical and scalable way: • Use a proven real-time backend architecture (WebSockets / event-driven system) • Integrate a reliable WebRTC layer for calls (optimized for low latency) • Containerize all services using Docker for easy on-prem deployment • Build a clean native iOS app in Swift with fast UI and proper push handling This ensures: • Fast performance (low latency messaging & calls) • Full control (no external SaaS dependency) • Maintainable code for your internal team I focus on building systems that are not just functional, but stable and scalable in real environments. I can start immediately and break this into clear milestones (messaging → file sharing → calls → deployment). Quick question: Are you open to leveraging existing open-source components where it makes sense, or do you prefer a fully custom implementation? Let’s build this efficiently and correctly.
