In the last few years, I have been developing a lot for Flutter. I love that it's declarative and responsive, that it gives cross-platform binaries of course, and that it's primed for modern development with separation of concerns and reusable widgets. My latest Flutter accomplishments have been extending the styling on widgets, building a Repository class I'm happy with, and learning about the different navigation patterns. I would be excited to talk about roles on your team if there might be a fit!

In recent years, I've also delved deeply into Flutter development, drawn to its declarative nature, cross-platform capabilities, and modern development paradigms. My latest achievements include extending widget styling, refining repository class structures, and mastering various navigation patterns. I'm enthusiastic about exploring potential opportunities within your team and discussing how my skills and experience align with your organization's objectives.
