PROFILE
Bruno Cunha
Bruno Carlos da Cunha contributed to the LedgerHQ/ledger-live repository over six months, focusing on end-to-end testing, CI/CD reliability, and feature delivery for mobile and web wallet flows. He expanded automated test coverage for cryptocurrency transactions, stabilized nightly E2E runs, and improved test isolation using TypeScript, JavaScript, and Docker. Bruno refactored test configurations, implemented feature flags, and enhanced error handling to reduce flakiness and runtime issues. His work included architectural simplifications, UI test adaptation, and CI workflow improvements, such as emulator cleanup scripts and build optimizations. These efforts resulted in more reliable releases and reduced maintenance overhead for the project.

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.

Oct 1, 2025Month: 2025-10 — Ledger Live focused on end-to-end testing stability and maintainability for wallet flows (receive, swap, earn, Ledger Sync). Consolidated test stability efforts, improved selectors and test IDs, and strengthened synchronization between web/app states. This work reduced flakiness, enabling safer releases and faster iteration on wallet features. Technologies demonstrated include Detox, TypeScript, Speculos-based testing, and UI adaptation to Tailwind CSS, with robust handling of webview synchronization and edge cases such as token duplication.

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.
