Hello, We are looking for a QT + C developer with JAVA knowledge that can optimize our existing program for Windows, Linux and Android (cross-platform). The program is a VPN (OpenVPN) program that is already developed yet it has a few issues when operating as a user. These need to be fixed. It is also developed without a user friendly interface. It is required to change the design as explained. The programs (Android, Windows and Linux) must become signed and added in the PlayStore and Ubuntu store. Budget $500. The project details are shared via GDocs, and are leading in the project. It is important that all the tasks are done. We will pay in two steps: 1. Fixing issues / bugs + automatic loading of certificates from an external database. Milestone 1 2. Design features, optimizing the user interface of the application + adding on stores. Milestone 2
