Software Engineer — Kube-DC, Kubernetes cloud platform

2024 – 2025

Built multi-tenant platform services for compute, networking, storage and VPCs on Kubernetes, running as a public PaaS and 4 on-premise installations.
Owned feature architecture, backlog prioritisation, CI/CD and deployment scripts; built the web console and its Node.js backend with Keycloak OIDC login.
Built the self-service developer platform: deploy from GitHub with automatic builds (Dockerfile or Railpack), a private registry per project, preview environments, managed databases and queues, and a hosted MCP endpoint that lets AI agents manage tenant projects, VMs and apps through LLM tool calls.
Ran observability on Prometheus, Grafana, Loki and Mimir with synthetic query probes and alerting; took part in the on-call rotation and led root-cause analysis of production incidents (e.g. an OpenBao out-of-memory crash loop traced to leaked namespaces).
Hardened the platform: fixed critical findings from a security review, narrowed RBAC, rolled out in-cluster TLS; Keycloak OIDC and OpenBao (Vault) for identity and secrets.
Operated Ceph storage and KubeVirt virtual machines: live disk migrations, scheduled VM snapshot backups, recovery during node maintenance.
Wrote Playwright end-to-end suites and CI quality gates; built MCP servers and used AI-assisted development day to day.
Kubernetes, KubeVirt, Docker, Node.js, React, Go.
