PROFILE
Wei Sun
Over thirteen months, contributed to MetaMask/metamask-mobile by delivering thirty features and resolving twenty-one bugs, focusing on mobile reliability, release automation, and codebase modernization. Worked extensively with JavaScript, TypeScript, and React Native to implement over-the-air update workflows, deep-link handling, and authentication enhancements. Improved CI/CD pipelines using GitHub Actions and introduced guardrails for the BN.js to BigInt migration, ensuring safer code evolution. Addressed platform-specific issues on Android and iOS, enhanced onboarding and modal UX, and strengthened security through dependency upgrades and origin validation. Maintained high code quality with ESLint, automated testing, and documentation, supporting efficient, stable mobile app releases.

Apr 1, 2026April 2026 monthly delivery focused on strengthening release automation, security posture, and codebase modernization for MetaMask Mobile (metamask-mobile). Delivered differentiated OTA and native release paths, improved CI reliability for iOS TestFlight, and introduced modern number utilities while aligning reporting workflows to business needs. Key outcomes: - iOS TestFlight CI workflow enhancements: introduced and refactored the build/upload pipeline using a temporary build branch and a reusable workflow to improve maintainability and reliability. (Commits: bfff4ec0569fc5ecbc633c5d13714d8306987855; 34edde32d0de9b626e4b93eeb8b3d2d41a26811b) - OTA release automation and versioning enhancements: added reusable Runway workflows, centralized environment configuration, and explicit OTA branch handling to streamline OTA releases and reduce manual steps. (Commits: 69b2afb3c088a817de14dddad3651f7de29d25e9; 366e9cca4e760cd6f664029e05297da44f12699f) - Runway OTA and native build workflows (phase 1): introduced dedicated entry points for OTA and native builds, enabling explicit control over release channels and versioning. (Commits: 764a031201bde844a57d2334d1644c5ba2213936; 4e11714e4a504224574ef52c80ac7d5c6ddb3b82) - Axios security updates and dependency cleanup: addressed a critical SSRF vulnerability by bumping axios to 1.15.0 across dependencies and CI scripts; included temporary bypass cleanup as part of secure upgrade. (Commits: f8a6fb8f556cc10f408b780ca98317e76dfbc04c; e80aaac1101013faf2f659769c639daef92439f8) - Slack/PR build metadata synchronization: ensured accurate build metadata propagation to Slack and PR comments to align with TestFlight uploads, reducing reporting gaps. (Commit: aedda91d81ddcf304d42625bc1da3327cf719a61) Technologies/skills demonstrated: - GitHub Actions / CI/CD orchestration, reusable workflows, and environment-driven releases. - Runway release automation, OTA vs native dispatch, and branch-based versioning. - Modern JavaScript tooling, including BigInt utilities groundwork (referenced in later work), and security best practices in dependency management. - Improved cross-team collaboration through standardized metadata reporting and changelog alignment.

Feb 1, 2026February 2026 monthly summary for metamask-mobile: Stabilized startup reliability on Android by addressing a crash triggered during cold start when notification permission changes could activate Notifee's BlockStateBroadcastReceiver before React Native was fully initialized. This targeted fix mitigates an Android ANR risk and improves first-run and startup consistency ahead of notification-permission flows. The change is captured in commit b5668644fe798ec6c7738d32ab8076e94397c8e5 (fix: Android ANR bug cp-7.64.0 (#25551)).

Sep 1, 2025September 2025 saw a blend of feature delivery, test stabilization, and release tooling improvements for metamask-mobile. Key outcomes include implementing the reassure API (#19010), stabilizing the test suite with comprehensive snapshot updates (including 097.test.ts), and modernizing release tooling with Yarn-based Husky, stable/main syncs, and enhanced changelog/versioning practices. Additional reliability came from Yarn deduplication and SDK communication layer bumps. These efforts reduce release risk, accelerate time-to-market, and strengthen platform reliability.
