Kirill (ponfertato) - System Administrator, Automation Engineer, Open Source Enthusiast.
Specialized in building fault-tolerant infrastructure, declarative configuration management (NixOS), and resource optimization on ARM-based platforms. Primary focus: privacy, reproducibility, and minimizing manual intervention.
Core Competencies#
System Administration & OS#
- Linux / NixOS: Deep understanding of OS internals, package management via Flakes, reproducible builds.
- Containerization: Docker, Podman. Image optimization, multi-arch builds (amd64/arm64), orchestration.
- Networking: Routing configuration (OpenWRT), VPN (WireGuard), DNS/DHCP, VLANs, traffic monitoring.
Automation & DevOps#
- CI/CD: GitHub Actions, GitLab CI. Building pipelines for testing and deployment.
- Scripting: Bash, PowerShell, Python. Automating routine tasks, log processing, API integration.
- Monitoring: Prometheus, Grafana, Alertmanager. Configuring metrics and alerting.
Hardware Platforms#
- ARM SBC: Orange Pi, Raspberry Pi. Optimization for limited resources, bootloader configuration, custom kernels.
- Self-Hosted: Deployment and maintenance of home server clusters (Nextcloud, Gitea/Forgejo, Media Server, Game Servers).
Methodology#
- Infrastructure as Code: Every system change must be defined in code and versioned.
- Reproducibility: Configuration must deploy identically on any machine.
- Security by Default: Closed ports, least privilege, data encryption.
- Pragmatism: Using tools that solve the problem, not tools that are “trendy.”
