Antoine Bellion developed zero wait time support for the Wait Node in the nocodb/n8n-fork repository, enabling workflows to execute immediately when a wait time of zero is specified. He updated validation logic to accept zero as a valid input and revised validation messages to reflect this new behavior. To ensure reliability, Antoine added targeted tests covering zero-wait scenarios, maintaining code quality and documentation clarity. Working primarily with TypeScript, Node.js, and testing frameworks, he addressed workflow latency by removing unnecessary delays, thereby improving user experience for instant execution cases. His work demonstrated focused engineering depth within a concise project scope.
