Andrii Andriushchenko focused on backend development for the WalletConnect monorepo, addressing connection stability and reliability to support longer-lived user sessions. He improved the WebSocket connection monitoring logic by increasing the heartbeat timeout from 31 to 35 seconds and refactoring the ping listener to reset the timeout on every ping event, rather than only once. This change, implemented in TypeScript and Node.js, resolved intermittent disconnects that previously affected user experience. By enhancing the reliability of connection monitoring, Andrii’s work reduced user-visible disconnects and support overhead, contributing to smoother onboarding and more robust session management across devices within the WalletConnect ecosystem.
