Trained FiSi (IT systems integration specialist), currently focused on networking, Docker, and routing infrastructure — with an eye on moving further into security.

I run a self-hosted HomeLab as a hands-on learning environment: Linux, networking, containerized services, monitoring, and security tooling, all documented and iterated on as I go.

• 🐳 Docker, networking, and a healthy obsession with self-hosting
• 💥 Breaking my own homelab so production never has to
• 🌙 Building infrastructure by day, breaking it on purpose at night
• 🍓 Turning a HP ProDesk and a Raspberry Pi into more problems than solutions

(Turns out most of those problems are also solutions if you wait long enough.)

🔭 Currently building: QuantWatch — a rule-based stock scoring/watchlist tool (FastAPI, Docker, FinBERT sentiment analysis). Not a recommendation tool, just a project to explore APIs, scoring logic, and deployment practices.

🛠️ Stack I work with:

• Infrastructure: Docker · Docker Compose · Linux (Ubuntu, Debian) · systemd
• Networking & Security: Nginx (reverse proxy) · UFW · CrowdSec (WAF/AppSec) · Tailscale (WireGuard-based mesh VPN) · Pi-hole · mkcert (local CA) · SSH
• Monitoring & Logging: Prometheus · Grafana · Blackbox Exporter · node_exporter · Loki/Promtail
• Backup: restic · Samba (SMB)
• Self-hosted services: Nextcloud · MediaWiki · Vaultwarden · Firefly III · Open WebUI · Ollama
• Backend development: FastAPI · SQLAlchemy · Alembic · PostgreSQL · MariaDB · Pydantic
• Data & ML: yfinance · Hugging Face Transformers · PyTorch · pandas · NumPy
• CI/DevSecOps: Git · GitHub Actions · CodeQL · Dependabot
• Shell/CLI: Starship prompt · btop

📈 Currently learning toward: IT security fundamentals — WAF/AppSec concepts, dependency scanning, secure secrets handling, hardening self-hosted services.
