PROFILE
Jorge Leandro Perez
During a two-month period, Leandro Perez developed and integrated a dynamic theming framework for the duckduckgo/apple-browsers repository, focusing on scalable design-system alignment and cross-platform parity. He architected a ThemeManager and supporting protocols in Swift and SwiftUI, enabling persistent, user-customizable color palettes and live UI updates across macOS app surfaces. The implementation included Figma-based color imports, feature flag management for safe rollout, and comprehensive unit testing to ensure reliability. By refactoring core UI components and centralizing theme logic, Leandro improved maintainability and developer velocity, delivering a robust foundation for future UI/UX enhancements without introducing regressions or unresolved bugs.

Oct 1, 2025October 2025 delivered an end-to-end Dynamic Theme System and Theming UI for the macOS DuckDuckGo Apple Browsers app, enabling live theme updates and automatic UI refreshes. The work established a scalable design-system approach with ThemeManager, ThemeStyle, and ThemeDefinition, and introduced internal-user gating and an Appearance UI with live previews. The implementation spans core UI surfaces (address bar, tabs, bookmarks, passwords, AI chat, downloads, popovers, and preferences) and is complemented by unit tests and design-system alignment efforts. The refactor to design-system primitives and internal flag governance positions us for safe, scalable rollouts and faster UX iterations.
