I work in Law Enforcement with a strong focus on digital forensics, cybersecurity, and applied AI.
My expertise spans evidence analysis, infrastructure design, and AI model development, bridging the gap between operational law enforcement work and cutting-edge technology.

I design, build, and investigate across multiple layers:

• 🔍 Forensic Analysis – Disk, network, and mobile investigations.
• 🛡 Secure Infrastructure – Proxmox VE clusters, OPNsense firewalls, PKI/CA hierarchies, Windows AD domains, WireGuard VPNs.
• 🤖 Artificial Intelligence – Training and fine-tuning LLMs (Qwen, Gemma, custom models), dataset structuring (Alpaca, Harmony), RAG pipelines, forensic LLM assistants.
• 🛠 Software Development – Python tooling, Swift/SwiftUI macOS/iOS apps, forensic automation frameworks.
• 🌐 Network & Systems – VLAN architectures, ZFS-based storage, NGINX reverse proxies, DNS/Unbound, Squid proxies.

• 🦈 Shark – macOS digital evidence collection app (Swift/SwiftUI, hashing, signing, encrypted packaging). Exclusively for law enforcement.
• 🌐 NetDiscovery – Python-based live and forensic network discovery system.
• 💬 EuroChat – AI-assisted forensic analysis of large-scale mobile datasets. Exclusively for law enforcement.
• 🤝 Nuclius – Central AI platform for orchestrating scalable LLM analysis. Exclusively for law enforcement.
• ⚖️ AIVI – Specialized LLM for German legal texts to support investigations. Exclusively for law enforcement.
• 🧠 LLM Server Cluster – Distributed infrastructure for large-scale LLM deployment.
• 📚 LLM Training Pipeline – Dataset preparation, fine-tuning, and GGUF export.
• 📊 Log Analytics – Visualizations for NGINX/DNS logs (IP/domain correlations, heatmaps, peak analysis).
• ⚡ BuckIQ – Automotive-grade DC-DC converter with battery protection.
