PROFILE
Michal
Over five months, Miso Szorad engineered mobile wallet features and infrastructure for the Emurgo/yoroi repository, focusing on user notifications, hardware wallet integration, and build reliability. He delivered cross-platform push and in-app notifications using React Native and TypeScript, implementing background tasks, feature flags, and analytics to enhance user engagement. Miso improved hardware wallet signing by refining COSE sign1 encoding and error handling, and stabilized builds through configuration management and dependency updates. His work addressed transaction parsing, notification relevance, and DApp connection flows, resulting in a robust, maintainable codebase that improved security, user experience, and development workflows across Android and iOS platforms.

Feb 1, 2025February 2025 — Emurgo/yoroi monthly summary Key features delivered - Nightly Build Notification and FCM Configuration: ensured nightly iOS builds have correct FCM configuration and notifications behavior, including entitlements and GoogleService-Info plist selection per bundle, plus a toggle to disable nightly pushes when needed. Commits: 760fd7a2997bd58899f80e3722eee508d0e42e94; 0f09c9f993253f595f243415c4768cd8e4c85b90 - Mobile Notifications UX Improvements: refined mobile notification experience with improved last-notification display, shadow tweaks, and suppression of notifications during wallet selection for a cleaner UX. Commits: 7e0ca10f465bdaa8210df637210ff539e370b317; 77c413ab6f7a9e99a4f445993c3d7fda8194f08b; 605de8b98f189da802deab23ad23686221c47e80 - Transaction Notification Reliability and Relevance: made transaction notifications more relevant and reliable by filtering based on app open time, avoiding noise during history viewing, and waiting for wallet sync before emitting. Commits: 4c48a1fda1e80d2f5e98393e5d60c586608b002f; 6f655e833b80478da305edca4ba98636d99c7a6b; 7b12e33b1fbdf8044864c795e7e58b904e9de6ca - DApps Connections Management Enhancements: added hooks for confirming and disconnecting dApps; ensured the connected dApps list is invalidated after disconnection to keep UI in sync. Commit: 912a954d988d6027bc05c998f72c4ef58fc9e915 - Hardware Wallet Signing Fix: fixed hardware wallet signing flow by correctly handling message data and constructing the COSE sign1 structure, with updated encoding and Storybook configurations. Commit: 929b9d279a36cc15e4657d08ab8a7f897b4019ac Major bugs fixed - Hardware Wallet Signing Fix: corrected COSE sign1 encoding and message data handling, stabilizing signing across devices and scenarios. Commit: 929b9d279a36cc15e4657d08ab8a7f897b4019ac Overall impact and accomplishments - Improved user experience and engagement: reduced notification noise, cleaner UX during wallet selection, and more relevant TX alerts. - Increased reliability and maintainability: robust navigation, dApps disconnection handling, and type updates reduce regression risk and streamline future work. - Strengthened security and correctness: corrected hardware signing flow to align with secure signing practices. - Scalable foundation for future work: refactors around dApps queries and route utilities enable faster iteration and UI consistency. Technologies/skills demonstrated - React Native, TypeScript, and mobile UX optimization - iOS FCM integration, entitlements management, and GoogleService-Info plist handling - Wallet synchronization logic and event-driven notifications - COSE sign1 encoding for hardware wallet signing - Route utilities and type-management updates (@yoroi/types) Business value - Enhanced user retention and satisfaction through reliable, relevant notifications and smoother onboarding for nightly builds and DApps usage; reduced support load from noisy notifications.
