Automation

• n8n workflows
  Event-driven automations for monitoring, alerts, backups, data transformation, and AI-augmented tasks.

• CLI automation
  Shell scripts and repeatable routines for server management, system checks and maintenance.

• AI-assisted tooling
  Using local models (Ollama) and Sim AI to accelerate documentation, publishing, analysis and troubleshooting.

DevOps

• Traefik reverse-proxy design
  Routing, services, middlewares, Cloudflare DNS-01 ACME, and containerized edge deployment.

• Docker best practices
  Clean Compose design, consistent networks, persistent storage, and environment secrets.

• Monitoring & observability
  Access logs, curl-based health checks, Netdata, n8n alerts, WireGuard uptime checks.

Tools

• Ollama – https://ollama.com
  Local model runner used for LLM inference, assistants and developer tooling (LLaMA/Qwen/Mistral).

• Sim AI – internal
  Web-UI AI agent for writing, analysis, automation and content generation.

• Netdata – https://www.netdata.cloud
  Lightweight real-time monitoring (disk, memory, CPU, network, Docker, etc.).

• VisiData – https://www.visidata.org
  Terminal spreadsheet for CSV, logs, JSON and large datasets.

• HTTPie – https://httpie.io
  Human-friendly HTTP client for API testing.

Debugging

• curl diagnostic toolkit
  Testing reverse proxies, SSL certs, router configs, DNS and caching.

• nftables debug logging
  Checking firewall decisions, packet drops and NAT behavior.

• Docker service inspection
  Network topology, logs, health checks, port bindings and container statuses.

Virtualization

• WSL & Linux subsystems
  Development, Docker, automation and testing on Windows.

• VirtualBox / QEMU
  Safe sandboxes for malware analysis, forensic labs and network simulations.

• Remote access tooling
  RustDesk, SSH keys, wire-level troubleshooting.
