01 / EXPERTISE

Cloud engineering.
Operational depth. Applied AI.

AWS architecture, Linux operations, automation, observability and AI-assisted development—grounded in production systems, published field notes and continuous learning. I connect design decisions with the realities of running, securing and paying for systems.

Production experience

Networking & edge delivery

DNS, health checks, load balancing and edge caching connect application behavior to the network. My Akamai project offloaded roughly 90% of requests from the origin during highly variable traffic.

  • Cache policies, TTL tuning and origin offload
  • Route 53, ALB health checks and HTTPS troubleshooting

Production experience

Linux, storage & virtualization

From early C++ development to Linux administration, VMware virtualization and storage troubleshooting. I look beyond CPU utilization to I/O wait, worker saturation and shared-storage constraints.

Automation & delivery

I turn recurring operational work into repeatable code and deployment workflows. CloudFormation and Python power this site; Ansible, Puppet, Git and GitLab CI/CD belong to my broader automation toolkit.

Operations & on-call

Observability & reliability

Monitoring should help responders act before customers report a problem. My experience spans Nagios, Zabbix, Checkmk, Grafana, Prometheus, ELK and CloudWatch.

  • TLS expiry, service health, SNMP diagnostics and trend analysis
  • Actionable alerts, escalation paths and 24/7 on-call response

Current engineering focus

Secure development & DevSecOps

Shift-left security combines security linting, dependency awareness and engineering review. I focus on actionable findings, least privilege and verified updates rather than treating a passing scanner as proof of security.

  • Dependabot triage, lockfiles and reproducible builds
  • Secure defaults, narrow IAM policies and automated quality gates

Coursework & hands-on labs

Containers & platform foundations

Container training and hands-on labs in Docker, Kubernetes and AWS container services. My focus is understanding how workloads are packaged, deployed and operated across a platform.

  • Containerization, orchestration and service deployment concepts
  • Kubernetes the Hard Way and documented ECS/Fargate training

Personal projects & recent learning

Applied AI & agent workflows

Codex helped me build Kraftwerk, digitize handwritten training notes and rebuild this site. Recent coursework extends that practical work into Claude Code, agent orchestration, RAG, MCP and Amazon Bedrock.

  • Human review, tested outputs and clear agent handoffs
  • Prompt engineering, multimodal input and Python/Streamlit coursework

Teams, change & communication

Technical leadership & delivery

I have led systems-administration teams, supported 24/7 operations and guided infrastructure change. Scrum Master and IT Escalation Manager roles connect technical decisions with prioritization, communication and incident response.
