In Oct 2025, the metamask-mobile team stabilized the mobile build/test pipelines while delivering a critical bug fix in a single repo: MetaMask/metamask-mobile. The work delivered a revert of environment/build variable precedence and an upgrade of logging/Sentry checks, alongside a broad CI/CD and infrastructure modernization that triggers E2E tests on build.sh changes, increases emulator resources for CI tests, and upgrades the iOS/Android E2E workflows across GitHub Actions and Cirrus CI. These changes reduce flaky builds, shorten feedback loops, and improve cross-platform release readiness, demonstrating strong execution in build systems, testing infrastructure, and observability.

In September 2025, Metamask-mobile delivered targeted CI/CD and iOS E2E testing improvements to accelerate feedback loops and increase test reliability. The work focused on optimizing the mobile pipeline, reducing unnecessary builds, and streamlining runner selection, with concrete changes to accommodate Cirrus-based iOS E2E tests and Detox config updates.

Month: 2025-07 — Delivered cross-repo E2E infra improvements for MetaMask desktop and mobile, accelerating test feedback and reducing maintenance burden. Desktop E2E: streamlined configuration by upgrading the test image to GHCR and removing Docker Hub credentials. Mobile E2E: migrated CI/CD to GitHub Actions with Detox, covering iOS/Android environments, pre-built artifacts, and test suites, replacing Bitrise. Outcomes: faster, more reliable test runs; lower operational risk; standardized CI/CD practices across metamask-extension and metamask-mobile.

May 2025 performance summary for MetaMask repositories. Focused on automating RCA data collection, enforcing PR quality gates, and stabilizing CI/CD pipelines across github-tools, metamask-mobile, and metamask-extension. Delivered concrete data-driven incident collection, tighter PR size controls, and more reliable test/status reporting to accelerate incident resolution and improve code quality.

April 2025 monthly summary for MetaMask extension: Delivered an End-to-End (E2E) Test Report Generator to improve visibility of CI/E2E results. The script parses XML test results from GitHub Actions, aggregates outcomes, and formats a human-readable summary with pass/fail/skip breakdowns, enabling faster triage and data-driven decisions.

In March 2025, modernized the CI/CD pipeline for metamask-extension by migrating Chrome E2E tests from CircleCI to GitHub Actions (soft launch) and introducing Firefox E2E testing, enabling cross-browser E2E execution within the CI pipeline. The changes reduce feedback cycle times, improve test coverage, and set the foundation for broader browser support.
