CHI Billing
I owned the backend for a billing workflow that moves from service import to invoice generation, human review, email delivery, and audit integration. It taught me that good automation keeps every manual checkpoint visible and recoverable. 我负责账单系统后端,将服务数据导入、账单生成、人工审核、邮件投递和审计集成串成完整流程。这个项目让我认识到:好的自动化不会掩盖人工节点,而是让每一步都清晰且可恢复。
