Projects

CMCC App Cloud Platform

Brief: CMCC App Cloud Platform used to intergate CMCC and its 3rd providers resources and pack them into solutions and products. Platform could manage lifecycle of solutions and products: Seek Advice, Make a Deal, Development and Continue Delivery. CMCC or its 3rd providers could publish their abilities (API, SDK etc) as product to platform and platform could provide authentication / authorization, mesurement for them.

Main Tech: Spring Boot, Lua, Quartz, Go, Kubernetes Operators (customized), Drone CI, Argo CD, Kube Vela, APISIX (customized) and Keycloak (customized).

Duties:

• Lead the designing of system architecture, responsible for tech selection, low-level abstraction of system core component.
• Product prototype design and write PRDs.
• Formulation of project development specifications.
• APISIX measurement plugins development with Lua.
• Keycloak plugins designing and development.
• Responsible of code review and code integration, control the release version.
• Design and tooling to improve development effciency:
  • auto commit lint
  • continues delivering of container image with Kaniko
  • auto semantic versioning based on git commit messages
  • one-line code to Open API versioning.
