Yann Menec developed a Post-Onboarding Landing Page for Nano Devices within the LedgerHQ/ledger-live repository, focusing on enhancing the user experience after device onboarding. He integrated the new landing page into the existing onboarding flow, enabling users to access post-onboarding actions such as buying cryptocurrency and syncing accounts. The implementation included developer settings entries and ensured seamless end-to-end UI integration, with clear traceability through linked commits. Yann utilized React and TypeScript, applying both front end and full stack development skills. The work addressed the need for a cohesive post-onboarding process, delivering a ready-to-rollout feature without introducing new bugs.
