Mobile VPN App Development

@Julian29

Hello, I HAVE 9+ YEARS OF EXPERIENCE in mobile app development with a focus on secure networking and protocol integration. I can build a lightweight, high-performance VPN client for both iOS and Android with modular, maintainable code. Core Features: • Reliable kill switch to block traffic if tunnel drops • Split tunneling to selectively bypass apps • Support for SSH, SSL, UDP, V2Ray, and WebSocket protocols • Expandable server location list via remote JSON configuration • Pre-provisioned profiles (no in-app auth) Deliverables: • Well-commented Kotlin/Java source code • Signed builds ready for TestFlight & Google Play internal testing • Deployment guide for server setup, protocol config, and adding endpoints • Short demo video or screenshots showing kill switch & split tunneling Technical Approach: • Use native networking APIs for speed and stability • Modular architecture for adding new protocols/servers easily • Background-safe execution and optimized battery usage I also have real-world experience integrating V2Ray and WebSocket transport layers in mobile VPNs, ensuring secure and performant connections. Thanks & regards, Julian

Hi there, I'm excited about your Mobile VPN App Development project. With extensive hands-on experience in Android development, security-focused networking, and scalable backend config, I can deliver a robust, low-footprint VPN client in Kotlin that meets your requirements. My approach centers on reliable kill-switch mechanics, precise split-tunneling controls, and flexible transport layers (SSH, TLS/SSL, UDP, v2ray, WebSocket), all wrapped in a clean, minimal UI. I will implement a modular server config system using a JSON-driven endpoint list so you can add endpoints remotely without code changes. Pre-provisioned profiles or embedded credentials will ensure a smooth, streamlined build. What I will deliver: - Clean, well-commented Kotlin/Java source with thorough in-line documentation and secure coding practices. - Signed release builds ready for TestFlight and Google Play Internal Testing, with a clear CI/CD and signing workflow. - Brief deployment guide detailing server config files, protocol setup, and how to extend endpoints. - A short device demonstration video or screenshots showing kill switch and split tunneling in action. I have real-world experience integrating v2ray and WebSocket transport layers into mobile VPN clients, and I can bring that depth to your project to ensure stability under real-world network conditions. What is the preferred endpoint format for the remote JSON config (e.g., a hosted URL vs. a Git-based config) and do you require any specifi

Hello, I can build your complete lightweight VPN app for both iOS and Android. A quick thought using VpnService API on Android and NetworkExtension on iOS gives you system level kill switch that blocks all traffic instantly if the tunnel drops . Split tunneling can be implemented app based or domain based so users choose exactly what goes through the VPN . For V2Ray support, I'll integrate Xray core which handles VMess, VLESS, and WebSocket protocols reliably . Existing apps like HTTP Injector and NetMod demonstrate this works smoothly on both platforms with proper configuration management . 1. Should the server list update automatically or require manual refresh? 2. Do you need logging for debugging or keep everything silent? Best regards, Kamran

@jeric5g

Hello, I’ve read your spec for a secure, lightweight VPN app with a kill switch, split tunneling, and support for ssh, ssl, udp, v2ray, and websocket. I’ll build a native Android solution in Kotlin (and provide parity guidance for iOS if needed) using VpnService for reliable tunnel control and per-app routing, keeping the UI minimal and the experience fast and stable. Embedded credentials with pre-provisioned profiles, plus a remote JSON config for expanding server endpoints, will ease ongoing maintenance. Deliverables cover clean, well-commented Kotlin/Java sources, signed builds for TestFlight and Google Play Internal Testing, a deployment guide, and a short demo video. Best regards, Jeric Gonzales

@SEOGlobalLLC

Hello, We understand you need a secure, lightweight iOS and Android VPN application prioritizing stability, speed, kill switch reliability, split tunneling, and support for SSH, SSL, UDP, V2Ray, and WebSocket with remotely expandable server configuration via JSON. SEO Global Team has extensive experience in Kotlin/Java and Swift mobile development, VPN protocol integration including V2Ray and WebSocket transports, Network Extension implementation, backend endpoint management, and performance-focused mobile architecture. We will build a minimal UI VPN client with robust tunnel management, system-level kill switch enforcement, configurable split tunneling, modular protocol abstraction, remote JSON server provisioning, thoroughly documented code, signed release builds, and verified on-device demonstrations. Will iOS require Network Extension with Personal VPN or Packet Tunnel configuration? Are server-side configs already prepared for all listed protocols? Should the remote JSON config be hosted on your existing infrastructure? Best regards, SEO Global Team

@oleksandrp60

Hi there Do you need iOS too, since you mention TestFlight, or is this Android only with Kotlin or Java source? Do you already have working server configs for ssh ssl udp v2ray websocket to test, plus the exact JSON format you want for remote endpoints? I will implement the tunnel using the native VPN framework per platform, with a kill switch that blocks traffic on drop and per app routing for split tunneling. I will keep profiles pre provisioned, add the remote server list loader, then deliver signed builds, a short setup guide, and proof video on real devices. Happy to discuss further on chat.
