Wolffun Game
- +Own backend service development for production products, focused on stability, scalability, and performance as request volume grows.
- +Design REST APIs for core business flows, processing client-side data and standardizing responses for downstream modules.
- +Structure the Golang/Python codebase with a clear separation between business logic, data access, and API layers for easier maintenance and feature growth.
- +Optimize request flow, database queries, and Redis caching — cutting database load by roughly 30% and reducing some processing flows from ~250ms to ~170ms.
- +Containerize services with Docker, help maintain the CI/CD pipeline, and collaborate on debugging production incidents to minimize impact on end users.
