With over 5 years of commercial experience in C# and .NET desktop development, I have a deep mastery of WPF, MVVM, and memory management. I have successfully profiled and optimized complex desktop applications, eliminating memory leaks and ensuring UI responsiveness. Additionally, my practical experience with C++/CLI interop aligns perfectly with your need to bridge .NET and native C++ core libraries. I am particularly excited about the opportunity to contribute to Skylum’s award-winning photo editing software. My background includes image processing and GPU acceleration, and I am comfortable refactoring legacy codebases into clean, testable architectures. I also embrace AI-assisted development tools and have integrated Copilot and Cursor into my daily workflow to boost productivity. I look forward to the possibility of joining your team and helping create incredible imaging experiences. Thank you for considering my application. Sincerely, [Your Name] Copy ### Sample Interview Questions Describe your experience with WPF and MVVM. How do you handle complex data binding and custom controls?I have over 5 years of WPF experience, implementing MVVM with Prism and Caliburn.Micro. For complex data binding, I use INotifyPropertyChanged, dependency properties, and attached behaviors. I create custom controls by extending existing ones and using templating, ensuring separation of concerns and testability.Can you walk through a time you identified and fixed a memory leak in a .NET desktop application?In a previous project, we had a memory leak due to event handlers not being unsubscribed. I used dotMemory and PerfView to capture snapshots and identified that large image objects were being retained by the Visual Tree. I implemented weak event patterns and disposed of resources in the finalizer, reducing memory usage by 30%.How do you approach integrating C++ libraries into a .NET application via C++/CLI or P/Invoke?I typically use C++/CLI for wrapper classes that expose native functionality in a managed way. I ensure proper marshaling of data types and manage memory using RAII and smart pointers. I also handle threading via Dispatcher for UI updates, and I validate interop boundaries to prevent crashes or deadlocks.Describe your experience working in an Agile environment, specifically with 2-week sprints. How do you handle corner cases and acceptance criteria?I have worked in Scrum teams for the past 4 years. For each story, I collaboratively define clear acceptance criteria and identify corner cases during sprint planning. I break down tasks into smaller subtasks and communicate continuously with the team and PO. I also participate in daily stand-ups and retrospectives to improve processes.How have you used AI-assisted development tools to improve your productivity?I integrate GitHub Copilot and Cursor into Visual Studio for code completion, generating boilerplate code, and writing unit tests. For example, Copilot helps me quickly create mock data and test scenarios. I also use AI to refactor code and suggest optimizations, always reviewing the output carefully. Skylum empowers millions of photographers to create incredible images. Our award-winning photo editing software combines AI-powered automation with full creative control. We make editing enjoyable, easy, and accessible for everyone. You’ll join an environment where growth, learning, and creativity are encouraged.
