About
Alex Hsieh / 謝明宏
Alex Hsieh（謝明宏）is a Cloud, DevOps, and SRE engineer with a focus on production reliability, platform engineering, and the practical application of AI to infrastructure operations.
His career has centered on helping teams operate services at scale — from designing cloud architectures and Kubernetes clusters to building the CI/CD pipelines and observability systems that keep them running. In recent work, he has turned toward AI automation: using large language models and agent-based systems to reduce toil in day-two operations.
Areas of Depth
- Cloud Architecture — Multi-cloud and hybrid designs on AWS and GCP, with emphasis on cost efficiency, security posture, and operational simplicity.
- Kubernetes & Container Orchestration — Production cluster management, GitOps workflows, and platform engineering for internal developer experience.
- SRE Practice — SLO/SLI definition, incident management, blameless postmortems, and toil reduction through automation.
- AI-Augmented Operations — LLM-powered diagnostics, intelligent alerting, runbook automation, and agent-based tooling for infrastructure teams.
- Developer Tooling — CI/CD pipeline design, infrastructure as code, and internal platform development.
Writing & Speaking
Alex maintains an active writing practice across multiple platforms:
- devops-with-alex.com — Primary site covering DevOps, SRE, and cloud engineering topics.
- blog.devops-with-alex.com — Longer-form articles and tutorials.
- ai-brain-alex.com — Exploration of AI agents and automation applied to infrastructure.
He has spoken at Cloud Summit 2025 (iThome), sharing practical lessons from the field with the cloud-native community in Taiwan.
Working Philosophy
- Boring technology, well-operated — The best infrastructure is the kind nobody has to think about.
- Automation with guardrails — AI and automation should reduce human cognitive load, not add new failure modes.
- Evidence over opinion — Claims in production should be backed by data: metrics, traces, and incident history.
What He Is Not
Alex does not position himself as a generalist “thought leader.” His work is grounded in hands-on engineering. When he writes about a tool or pattern, it is because he has used it in production or evaluated it seriously against alternatives.
