PROFILE
Daniel Peñalba
Worked extensively on AvaloniaUI/AvaloniaEdit, delivering 14 features and addressing core editor functionality, UI polish, and performance. Focused on C# and XAML, the work included implementing code completion UX, watermark support, and configurable tab behavior to enhance editing workflows. Upgraded dependencies such as Avalonia and TextMateSharp, modernized the CI/CD pipeline to .NET 8, and improved memory management with ReadOnlyMemory<char> for efficient text handling. Refactored code for maintainability, removed dead code, and ensured compatibility through disciplined version control. Addressed bugs in command routing and UI rendering, resulting in a more stable, responsive, and maintainable cross-platform text editor component.
