* Real-time quote: Our Go server keeps users' subscribes on products and dispatch real-time quote to them through WebSocket.

* Order: To ensure the integrity of orders, we use RabbitMQ for making orders.

Backend development of a gaming platform: including game logic, member info/history,  API concatenation and odds/risk calculation. (using PHP mainly)

Database design & maintenance. (MySQL/Redis/proxySQL/AWS RDS)
* I've re-design our data structure for Redis so that our website could handle thousands of user active online other than break down when only tens of users online.
* Add composite keys for frequently used queries; Write crontab for automatically periodical DB backup;Make sure tables are all normalized.
* nginx, haproxy, jenkins, AWS configuration .
