To reach the next level you'll need to develop:
Conducts code review for Qt/C++ code. Checks memory safety, thread safety, Qt best practices. Provides constructive feedback, suggests alternative solutions. Reviews QML code.
Applies Git rebase, cherry-pick, bisect for debugging. Configures Git hooks for pre-commit checks (clang-format, lint). Works with Git submodules for Qt dependencies. Resolves merge conflicts in C++/QML.
Applies MVVM with Command pattern through Qt. Uses QAbstractListModel for ViewModel, implements filtering through QSortFilterProxyModel. Organizes navigation through StackView and Router.
Independently develops Qt applications with QML and Qt Quick. Uses Model/View Architecture (QAbstractItemModel). Works with Qt Network, QThread and Qt SQL. Understands ownership and QObject lifecycle.
Structures tests by modules with separate test suites. Uses QTest::addColumn for data-driven tests. Introduces code coverage through gcov/lcov. Mocks dependencies through GMock or manual stubs.
Configures clang-tidy with Qt-specific checks. Uses cppcheck and PVS-Studio for static analysis. Applies RAII and smart pointers (QScopedPointer, std::unique_ptr). Writes self-documenting code.
Implements thread pool through QThreadPool and QRunnable. Uses QMutex, QReadWriteLock, QSemaphore for synchronization. Applies QtConcurrent with QFuture/QFutureWatcher for async operations. Avoids race conditions.
Manages memory in Qt with implicit sharing (COW) and move semantics. Uses QSharedPointer for shared ownership. Analyzes memory leaks through Qt Creator memory profiler. Optimizes allocations through QVarLengthArray.
