Personal projects and proof-of-concepts
In prototyping, AI, infrastructure, and mechanics
Industrial Process Equipment
Automated process equipment for industrial production. Mechanical design in CAD with stainless steel chassis and flow systems, hydraulic systems, custom PCB with sensors, PLC control with HMI and feedback loops, safety analysis per ISO 13849, and CE marking. Production-ready machine with <2% process variation.
AI-Powered Robot Platform
Prototype for autonomous navigation and object recognition. Raspberry Pi 5 with camera, ultrasonic sensors, and gripper arm. Local AI inference via Ollama (llava for vision), Home Assistant integration, manual control via PS4 controller, and autonomous navigation. Proof-of-concept for AI-driven robotics.
Local AI Inference Infrastructure
GDPR-compliant local AI hosting. Dual ASUS RTX 3090 Turbo (48GB VRAM total) with GPU passthrough via Proxmox. Runs models with 70B+ parameters completely offline — Qwen2.5 72B, Llama 3.3 70B. Faster-Whisper for transcription, Piper for text-to-speech. Demonstrates that powerful AI doesn't require cloud services.
Multi-layer Network Security Stack
Segmented network with multi-layer threat detection. OPNsense firewall with VLAN segmentation, CrowdSec for crowd-sourced threat intelligence (76k+ packets blocked/week), Suricata IDS/IPS, AdGuard Home for DNS filtering, geo-blocking. Result: 95%+ automatic threat blocking, zero intrusions.
Virtualized Infrastructure with Automated Backup
Proxmox cluster with KVM/LXC, automated backup of 13 VMs/CTs via N8N workflows. Wake-on-LAN from Home Assistant, automatic shutdown after completed backup. Zero-touch with 100% automation and energy savings through on-demand operation. New test environment in under 5 minutes.
Smart Home with Industrial Automation
Home Assistant as central hub, N8N for complex automation with AI-driven decision logic, MQTT for device communication, Ollama for natural language control. VLAN segmentation isolates IoT devices from the rest of the network. AI-assisted automation with secure IoT integration.
Performance Optimization — Toyota Supra MK4
Complete rebuild of Toyota Supra MK4 from twin-turbo to single turbo setup. New fuel system, modified camshafts, reinforced automatic transmission. The project required systematic planning and deep understanding of mechanics, hydraulics, and thermodynamics — the same methodical approach I apply to industrial projects.
