For more than 18 years, I have been utilizing JavaFX, Swing, and Java Core to professionally design and develop rich client and desktop applications, including their user interfaces, business logic, installation packages, and automatic updates. Additionally, I have built several websites and conducted usability, functional, and automated testing for both web and desktop applications. I strive to write efficient Java code and have a strong understanding of design patterns and software best practices, such as information hiding, separation of concerns, and code reuse. As a collaborative team member, I maintain a quality-focused mindset and possess a keen sense of design.
