# IoT_Engineer | CCTV_Architect | Automation_Dev

I build security and automation systems that actually work — IP-based CCTV, Home Assistant, Node-RED flows, and Shelly device integrations. Privacy-first, on-prem, and built to last.

Background

I design and implement integrated security and automation systems — from camera placement to NVR configuration, MQTT broker setup to Node-RED logic flows. My setups are clean, dependable, and fully under your control. No cloud subscriptions, no lock-in.

DEBUG

Approach

I treat smart home and security systems like production infrastructure: documented, monitored, and designed to fail gracefully. Every automation has a fail-safe. Every camera has a purpose.
