Senior Android & iOS Security App

@AwaisChaudhry

Hello, I understand you need a senior mobile developer to lead cross‑platform Android and iOS security work, focused on a endpoint agent with VPN/DNS/networking capabilities and stores publishing. I will design a clean, secure architecture for both platforms, implement robust networking, VPN service integration, and ensure store readiness, with clear code structure, reviews, and CI/CD integration for smooth remote collaboration. My approach is to establish a security‑first baseline, implement scalable modules for DNS/VPN networking, and deliver production‑ready apps with clear documentation and test coverage.

I’ve worked on security-focused mobile apps that needed stable VPN and DNS handling on both Android and iOS. For example, I helped a client in cybersecurity build an endpoint agent that integrated with network extensions and Android VpnService, ensuring reliable connection and minimal battery drain. To get started, I’d first review the current architecture and see how the network layers are implemented. Are you targeting any particular VPN protocols or focusing on custom DNS filtering? Also, do you have existing Go backend services that the app communicates with, or would those need to be built alongside? I can lead the development to ensure smooth cross-platform feature parity and handle app store submission processes efficiently. I’m ready to jump in and start reviewing your codebase or detailed specs right away.

I’m not here to just bid and wait. I’ve already visualized the fix for that one specific gap in your project that usually drags these projects out for weeks, and keep you from looping back for revisions later. If you’re serious about getting this done right the first time without the back-and-forth, hit me up in the chat, and I’ll show you exactly what I mean I guarantee it’ll be the most helpful 5 minutes of your day and will take the entire weight of this project off your shoulders.

You need a reliable cross-platform endpoint agent that survives OS updates and background restrictions — I’ve built exactly that kind of client. The real challenge isn’t the tunnel itself but consistent background behavior, secure key storage, and predictable App Store/Play Store submissions across Android and iOS versions. I recently led development of an enterprise VPN + DNS endpoint client: Android using VpnService, iOS using Network Extension, with a Go control plane and successful App Store / Play Store releases. I’d start with a short security/code audit (or review your spec), then implement the native VPN/DNS modules in Kotlin and Swift, wire them to the Go backend for policy/control, enforce Keystore/Keychain protections and cert pinning, and set up CI/CD and store submission checks to avoid rejections. I keep telemetry minimal and privacy-first so you can debug installs without exposing user data. Is this a greenfield project or do you have an existing repo/architecture I should review first?
