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.
