PROFILE
Bruno Cunha
Bruno Carlos da Cunha engineered robust end-to-end testing frameworks and reliability enhancements for the LedgerHQ/ledger-live repository over seven months. He expanded automated test coverage for critical wallet flows, including swaps and cryptocurrency transactions, and stabilized CI/CD pipelines to reduce flakiness and accelerate release cycles. Leveraging TypeScript, JavaScript, and Docker, Bruno refactored test configurations, implemented dynamic test IDs, and introduced feature flag management to support evolving UI features. His work included architectural simplifications, improved error handling, and test isolation strategies, resulting in more deterministic outcomes and reduced maintenance overhead. These contributions deepened test coverage and strengthened release readiness for Ledger Live.

Dec 1, 2025December 2025 — Ledger Live E2E testing and reliability enhancements. Delivered major test stability improvements across end-to-end swap flows, introduced a feature flag for LLM Account List UI testing, and enhanced test isolation with randomized Speculos container names and ports. Also addressed key flaky behavior and added resilient address handling to prevent runtime errors in transaction flows. These efforts reduce CI noise, increase deterministic test outcomes, and improve coverage for critical transaction and account flows.

Sep 1, 2025September 2025: Expanded end-to-end test coverage for Ledger Live with BTC/ETH/USDT and ENS, and stabilized nightly E2E runs through account/currency config fixes. Delivered new end-to-end test cases, test configuration refactor, and dynamic test IDs with device labels to improve test isolation. Fixed nightly failures by aligning ENS tests with accounts supporting ENS and ensuring correct BSC_POL in receive flows. These efforts increased test coverage, reduced flaky tests, and accelerated feedback into release cycles.
