Industrial Automation · Secure Gateways · Linux Systems Engineering · Cybersecurity
Based in Germany — developing on and for Linux.
Systems engineer and developer building robust, secure, and practical infrastructure for industrial environments and high-security systems.
Current focus areas:
- Network security appliances with TLS inspection and inline IPS (Suricata)
- Network discovery and scanning tooling
- Simulation & testing tools for industrial protocols (Modbus)
- Comprehensive Linux systems engineering knowledge bases
Strong focus on real-world deployability, security, clean architecture, and honest, evidence-based project maturity labeling.
- os-nxtgenappliance — Alpha / Pre-Production OPNsense security plugin: outbound TLS inspection with inline Suricata IPS, inbound reverse-proxy/WAF, enforced DoT DNS, identity-aware scoped policy
- Phimantic-IPS-Security-Appliance — standalone Suricata/TLS inspection appliance (C11 proxy, FlowBus verdict enforcement, fail-closed security model)
- squid-ng — laboratory and research proxy fork (Squid-based two-proxy TLS inspection with external IDS/IPS verdict path)
- advanced_network_scanner — cross-platform Rust LAN scanner with CLI-first architecture and optional WebSocket server
- advanced_modbus_server_dummy_endpoint — Modbus TCP simulation and testing server with browser-based dashboard
- linux-engineering-playbook — Linux systems engineering documentation: GPU/CUDA, Proxmox VE, Python environments, services and administration
Preserved pre-production snapshots. Frozen, read-only, kept for reference — not production-ready.
