Software Engineer
Full-time | Onsite | China
- Developed an ACL management microservice based on GoVPP using Golang, leveraging Redis for storing intermediate states. Registered RESTful APIs to an API gateway, achieving a unified access control solution.
- Designed and developed a log collection tool with Golang, uploading logs to a configured server via SFTP, providing a web-based configuration page built with Vue.js for seamless parameter setup. Additionally, an installation script written in Shell facilitates easy integration with other services.
- Led the development of a routing scheduling management microservice with Golang, which utilizes Kafka and Redis to capture upstream routing topology data-changing. It calls the routing path calculation DLL through CGO and exposes RESTful APIs for downstream services to retrieve routes. It is packaged as a Docker image and deployed with Kubernetes for multi-instance deployment with Zookeeper, ensuring scalability and high availability.
