Skills

Technical focus

Just the areas I actually care to work in.

I am self-taught, with knowledge built through practical work, constant learning, and years of solving real infrastructure and operations problems.

Linux systems

  • Debian
  • Ubuntu
  • System administration
  • Performance tuning
  • Troubleshooting

Deep hands-on experience with Linux environments, especially Debian and Ubuntu, across administration, maintenance, debugging, and optimization.

Cloud infrastructure

  • AWS
  • Large-scale environments
  • Networking
  • Service architecture
  • Operations

Managing and operating cloud infrastructure on AWS with a focus on resilience, clarity, and sustainable long-term operation.

Automation

  • Terraform / OpenTofu
  • SaltStack
  • GitHub Actions
  • Bash
  • CI/CD

Automating the repetitive parts without creating a machine nobody wants to touch later.

CI/CD

  • Jenkins
  • Pipeline design
  • Build automation
  • Release flow
  • Deployment workflows

Strong experience with Jenkins pipelines and delivery processes that need to stay dependable as systems grow.

Monitoring & observability

  • Grafana
  • InfluxDB
  • Telegraf
  • New Relic
  • Diagnostics

Monitoring is only useful when it helps answer real operational questions. Monitoring should support decisions, not just produce dashboards that look expensive.

Working principles

  • Reliability
  • Clarity
  • Simplicity
  • Maintainability

Tools are secondary. The goal is a system that works, can be understood, and can survive handover.
