PROFILE
Diogo
Worked on the simplex-chat/simplex-chat repository, delivering cross-platform chat features and reliability improvements across Android, iOS, and desktop. Over four months, built onboarding flows, unified chat tagging, group member mentions, and a message reporting system, focusing on user experience and safety. Implemented features using Kotlin, Swift, and Jetpack Compose, integrating backend APIs for authentication, notifications, and moderation. Enhanced chat navigation with pagination, reactions, and real-time group updates, while stabilizing UI elements and preventing data loss through confirmation prompts. Addressed bugs in navigation and formatting, standardized media handling, and improved build reproducibility, resulting in a more robust, maintainable messaging platform.
