A cross-platform application that helps to synchronize all types of files with cloud services. Our main task is to redo an old module and update other parts of the application accordingly.
Every country, big or small, is impacted by cyber crimes to some extent. Germany is not an exception. Citizens and organizations working in Germany face the wrath of malicious hacks, ransomware attacks, phishing schemes, and more. There is a strong awareness of the cybercrime threat in the country and businesses do their best to stay ahead of the game.
Our client is a German-based company, an award-winning online security app creator, with over 14 million users worldwide. In the initial solution of our client, some crucial modules, in particular, required improvements to synchronize all types of files with cloud services.
The list of required improvements included:
– Easy-to-use, secure cloud storage to store all types of files from PDF to HD videos;
– 100% files encryption, backup, synchronization, and data protection;
– Opportunity to encrypt every single file separately.
Our client was looking for experts with:
– Solid knowledge of cross-platform development for mainstream desktop and mobile operating systems;
– Experience creating highly competitive software;
– General knowledge of popular networking protocols including WebDAV, HTTP, and FTP;
– Solid knowledge of popular cryptographic algorithms.
The end goal was to have a cross-platform application that can handle file upload and download alongside encryption and decryption.
– Create clean, maintainable, performant, and tested code in C, C++, and Python
– Solve architectural problems with different modules and CMake/conan build system
– Wrap curl and use libSodium, and OpenSSL to handle data encryption and networking
– Use an abstracted library from the Qt application to be an independent and cross-platform module for the logic

As for me, this cloud storage project is a transitional period in my professional experience. It contains a major part of all the stuff I already know, so I can perfect my skills and fill the gaps. Also, there were architectural problems I noticed pretty early in the development process and thus helped to prevent possible issues. This fact increased confidence in the skills of our development team. And of course, the team matters! The communication is pretty friendly and productive.
