Sean Hagstrom developed and maintained user-facing features and core infrastructure for the status-im/status-mobile and status-im/status-go repositories, focusing on mobile UX, notification systems, and build reliability. He implemented Firebase-based push notifications, unified notification preferences, and improved onboarding flows, using ClojureScript, Go, and React Native. Sean addressed performance and reliability by optimizing chat rendering, enforcing deterministic Nix builds, and refining error handling in authentication and messaging. His work included backend integration, database migrations, and CI/CD automation, resulting in more stable releases and improved user engagement. The engineering demonstrated depth in cross-platform mobile development, configuration management, and continuous delivery practices.

May 2025: Delivered News Notifications Integration in onboarding and settings for the status-mobile app, enabling Firebase-based news notifications with a feature-flag controlled rollout. Updated onboarding flow and notification settings UI to provide clearer opt-in controls and streamlined configuration. Focused on delivering a solid foundation for timely user-facing updates with safe, incremental release.

April 2025 performance: Delivered cross-repo notification features and stability improvements with a clear path to targeted user engagement. Key features delivered across two repos include a unified notification preferences framework in status-go with three toggles (news_notifications_enabled, messenger_push_notifications_enabled, news_feed_enabled); status-mobile groundwork for notification prefs and Messenger notifications; and Firebase Cloud Messaging push support for iOS/Android, with FDroid build considerations. Maintenance included a version bump to 2.33.0 and safe-area dependency updates to improve stability. Impact: enhanced cross-platform consistency, improved user engagement controls, and safer release processes. Technologies/skills demonstrated: Go, mobile (iOS/Android), submodule management, Firebase Cloud Messaging, DB migrations, tests, and CI/build alignment.

February 2025 focused on reinforcing build determinism and release reliability for the status-mobile mobile stack. Implemented deterministic version derivation for go-mobile Nix builds by deriving 'version' and 'cleanVersion' from the version JSON in the Nix local source, ensuring reproducible builds across environments. This change strengthens artifact integrity, CI stability, and release traceability.
