May 2026: Delivered the AgentflowV2 Scheduling System for flowise with automated, time-based execution of flows. Core delivery includes ScheduleQueue (BullMQ), scheduleService (create/update/disable schedules), schedule validation, and support for last-day-of-month scheduling. UI/UX: added TimePicker, WeekDaysPicker, MonthDaysPicker, DatePicker, and an IANA timezone selector integrated with chatflow and CanvasHeader; updated NodeInputHandler to support scheduling inputs. Implemented endpoints for schedule status and enable/disable actions, along with robust validation to prevent misconfigurations. Quality and setup: aligned ScheduleRecord interfaces with nullable fields, fixed tests, and hid scheduling inputs from non-scheduling packages. Tech stack and practices demonstrated: BullMQ, cron/node-cron, TypeScript interfaces, UI components, REST endpoints, IdentityManager integration, and comprehensive unit testing. Business impact: automated, reliable, and scalable scheduling reduces manual intervention, improves workflow throughput, and enables more predictable agent-flow executions across flows.
