Gap analysis: skills to develop
To reach the next level you'll need to develop:
Implements auto-update through Qt Installer Framework or Sparkle/WinSparkle. Configures delta updates, signature verification. Works with update channels (stable/beta/nightly).
Conducts code review for Qt/C++ code. Checks memory safety, thread safety, Qt best practices. Provides constructive feedback, suggests alternative solutions. Reviews QML code.
Profiles C++/Qt code through perf, VTune, Instruments. Analyzes CPU cache misses and branch mispredictions. Uses QElapsedTimer for micro-benchmarking. Optimizes critical path based on profiling results.
Configures cross-platform builds: NSIS/WiX for Windows, .deb/.rpm for Linux, .dmg for macOS. Automates packaging through CMake CPack. Signs binaries for Windows and macOS.
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.
Optimizes Qt application startup time through lazy initialization and preloading. Reduces event handling latency through event loop optimization. Uses Qt Quick Compiler for accelerating QML loading.
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.
Selects optimal Qt containers (QHash vs QMap, QVector vs QList) based on algorithmic complexity. Implements tree traversal algorithms for Qt Model/View. Analyzes bottlenecks through profiling.
Applies QFuture/QPromise for async operations in Qt 6. Implements non-blocking I/O through QIODevice. Uses event filtering (QObject::installEventFilter) for custom event handling.
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.
Implements MVC/MVVM through Qt Model/View Framework. Applies Command for undo/redo (QUndoStack). Uses Decorator for extending QWidget functionality. Understands Composite in Qt widget tree.
Designs class hierarchies considering Qt ownership model (parent-child). Uses abstract interfaces for DI. Applies Q_INTERFACES for runtime type introspection. Understands mixin through multiple inheritance.
Profiles Qt applications through Heaptrack and Massif. Analyzes allocation patterns, finds hot allocation sites. Uses AddressSanitizer for detecting use-after-free and buffer overflows.
Creates custom data models through QAbstractItemModel with hierarchical structure. Uses QVariantMap and Q_PROPERTY for data binding in QML. Optimizes implicit sharing usage in Qt.
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.
