It gets user data and sends content from Big Data Team through Kafka Topic. Due to the large number of Binance users, this system focuses on performance. • One month after joining, I worked with a colleague to develop a CRM (Workflow) system. In this system, users can meet their needs through drag and drop. For example: after receiving user information, users must meet certain conditions before they can do something. These actions were taken. This system was created from scratch, and the backend was developed and launched smoothly by just two people.
