Over 11 months, contributed to the signalapp/Signal-iOS repository by delivering 79 features and resolving 71 bugs, focusing on messaging reliability, user experience, and accessibility. Built and refined core features such as polls, pinned messages, member labels, and group termination flows, ensuring robust cross-device synchronization and data integrity. Leveraged Swift, Objective-C, and Protocol Buffers to implement secure backup systems, UI/UX enhancements, and protocol-driven messaging logic. Emphasized accessibility and localization throughout, with thorough testing and release management. The work demonstrated depth in asynchronous programming, database management, and system integration, resulting in a more stable, user-friendly, and maintainable iOS messaging platform.
April 2026: Delivered key enhancements in Signal-iOS to strengthen group termination handling and thread integrity, boosting cross-device reliability and business value through more predictable messaging behavior and reduced support overhead. Implemented end-to-end group termination improvements: enable group termination receive, refined termination strings, skip restoring terminated groups from snapshots, and added local deletion semantics to maintain consistency across devices. Also hardened thread integrity for polls and edits by validating thread IDs and ensuring edits attach to correct threads, with storage-service-backed restoration logic fetching the latest state when restoring groups. These changes reduce user confusion, prevent stale/terminated state reappearance, and improve overall messaging reliability while showcasing strong proficiency in storage integration, data modeling, and Swift-based iOS development.

October 2025 (signalapp/Signal-iOS) delivered a comprehensive poll framework uplift in the iOS client, focusing on reliability, UX polish, and cross-device consistency. Key outcomes include a robust end-of-poll messaging lifecycle with proper termination and error handling, UI/UX enhancements for the voting flow, and targeted improvements to notifications and routing for poll-related events. The initiative also established cross-device synchronization of polls (messages and votes) and introduced polls backups, alongside the initial implementation of the first round of polls and internal polling support. Quality improvements address edge cases such as end-poll notifications requiring a threadId, focus behavior after deleting poll options, handling spaces in poll creation, and parity fixes for Android/desktop handling of poll bodies. Technologies/skills demonstrated include: iOS Swift development, UI/UX polish, network-synced data for cross-device polling, notification routing, data backups, and improving client parity across platforms.
