I have full access to a PHP code-base that I can share immediately. I already know exactly which file and function contain a hidden back door; I just need a seasoned developer to: • remove every trace of that back door cleanly, • rebuild/package the application so it runs flawlessly after the fix, and • verify the change with a quick security review and functional smoke test. You’ll receive the source archive, a short note pointing to the suspect section, and the steps I normally use to deploy. Hand back the cleaned code, a brief changelog, and confirmation that the application still behaves as expected on a standard LAMP stack.
基于C语言（C/C++）的Windows原生应用程序需围绕已验证的P2P远程传输引擎进行扩展或重构。当前首要任务是交付稳定版本，实现无需中央中继服务器的安全设备间通信，随后逐步迭代完善。 首个里程碑交付成果 • 两台PC间高速端到端加密文件传输 • 低延迟远程桌面控制，支持自适应屏幕缩放 • 选定文件夹的持续无冲突实时数据同步 源代码须为规范清晰、注释完善的C语言代码，支持MSVC或MinGW编译环境，并采用您曾实现的P2P协议（含UDP穿孔、NAT穿透等技术）。请重点展示您过往工作中，自主开发的协议栈在无需中继的情况下实现Windows机器间数据或屏幕传输的案例；此类实战经验将成为选择长期合作伙伴时最重要的考量因素。 不设硬性截止日期，质量与可维护性为首要原则。预计初始版本发布后将持续协作，以优化性能、强化安全性，并将功能移植至更多平台。

We are seeking an experienced **iOS developer** to assist in completing and optimizing our iOS VPN application. The developer will need to synchronize all features and logic from the latest Android version to the iOS version, address existing issues in the iOS app, and update and optimize backend code to ensure compatibility and performance with the iOS client. Our VPN protocol is **V2ray**, and the iOS client uses **sing-box** with integrated membership features. **Project Requirements:** 1. **Feature Synchronization**: Sync all functionalities and logic from our latest Android VPN version to the iOS version. Ensure that the user experience on iOS aligns with that on Android. The iOS and Android clients primarily differ in the VPN client implementation, but they both use the same...
