Core Persona
Jack Li
I build infrastructure systems with a focus on availability, Linux middleware, Kubernetes edge networking, and digital sovereignty.
My background is heavy-industrial full-stack engineering: Java, Spring, Linux, backend services, deployment systems, and production operations. Over the years, that work pulled me closer to cloud-native orchestration, HA architecture, and the parts of infrastructure that usually only get attention after something breaks.
Right now I spend most of my time on Kubernetes, the CNCF stack, AWS infrastructure, Cloudflare security layers, and AI-assisted engineering workflows with Codex and Claude Code.
Tactical Stack
- Infrastructure & Orchestration: Kubernetes, Docker, containerd, Helm, Ansible
- Cloud & Edge: AWS infrastructure, Cloudflare Zero Trust, WAF, VPC peering
- AI-Augmented Engineering: Codex, Claude Code, MCP, SKILL-based workflows
- Data & Backend: MySQL HA, Redis, Kafka, Java and Python services
- CI/CD & DevOps: Jenkins pipelines, deployment automation, release operations
Support the Ledger
I write technical notes from real system work: build logs, failure analysis, infrastructure decisions, and post-mortems. No ads. No tracking.
