I already have fully functioning VPN apps on Android and iOS. I now need an experienced mobile developer to take them a step further by: • Fixing the most pressing bugs that affect stability and user experience • Updating all third-party SDKs, libraries, and native dependencies to their latest stable versions • Implementing a couple of lightweight new features (we’ll pin down specifics together once you’re on board) The goal is to keep the existing codebase clean, secure, and store-compliant while improving overall performance. What I’m looking for • Proven track record working on VPN or network-heavy apps (please include store links or Git repos) • Solid knowledge of Kotlin/Java for Android and Swift/Obj-C for iOS • Familiarity with common VPN protocols, encryption handling, and Apple/Google submission guidelines Acceptance criteria 1. No critical crashes or security warnings after your fixes 2. All targeted SDK versions meet the latest Play Store and App Store requirements 3. New features function smoothly on both platforms without introducing regressions If you thrive on tightening code, updating frameworks, and polishing user experience, let’s talk. Share your most relevant VPN projects, outline your approach, and include an estimated turnaround time.
