PROFILE
Dominik Guzei
Dominik Guzei contributed to the input-output-hk/lace repository by building and refining features that improved wallet onboarding, cross-module state synchronization, and user experience reliability. He unified collateral handling logic across wallet modes, reducing transaction failures and simplifying code paths using TypeScript and React. Dominik enhanced onboarding by implementing dynamic language synchronization and a close button, and addressed navigation race conditions to ensure stable routing. He also refactored end-to-end testing utilities with JavaScript and WebdriverIO, increasing test maintainability. His work demonstrated depth in cross-module coordination, UI/UX design, and debugging, resulting in more robust, maintainable, and user-friendly wallet application flows.

Mar 1, 2026March 2026 — Lace: Key deliverable: Cross-Module Network Type Synchronization to ensure the app consistently reflects the active network (mainnet/testnet) across components by syncing settings between version 1 and the LMP service. Major bugs fixed: resolved network-type reflection drift across modules (commit cc36e5dd7294975ccdafcc63495dc870ea743438) under fix: sync network between v1 and lmp (#2182). Overall impact: improved reliability of network state propagation, reduced user confusion, and stronger deployment confidence. Technologies/skills demonstrated: cross-module coordination, end-to-end traceability, Git-intensive change management, and service integration between v1 and LMP.
