PROFILE
Michal Zak
Over a nine-month period, contributed to the trezor-suite repository by building and refining end-to-end testing infrastructure, onboarding flows, and multi-cryptocurrency support. Leveraged TypeScript, Playwright, and React to modernize test suites, stabilize onboarding for assets like BTC, ETH, and LTC, and enhance test reliability through improved setup, teardown, and recovery mode persistence. Addressed onboarding UX by enabling multiple network symbols post-wallet creation and reduced test flakiness with robust initialization and retry logic. Integrated analytics event tracking and Solana-specific flows, while maintaining clear documentation and repository hygiene. The work improved release confidence, onboarding experience, and automated QA coverage for critical user paths.

Mar 1, 2026March 2026 (trezor/trezor-suite) focused on strengthening QA through automated end-to-end testing of the device forget flow. Delivered a new end-to-end test that validates forgetting a device across USB and Bluetooth, including modal and confirmation steps. No major bugs were closed this month; the emphasis was on expanding automated coverage to reduce regression risk and improve readiness for upcoming releases. The work provides clearer validation of user flows and reduces ambiguity around device management edge cases.
