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.

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.
