+## Core Skills
+
+- **ESP32-S3** — embedded development, low-level hardware
+- **Voice AI** — hotword detection, speech-to-text, local LLM
+- **Home networking** — DNS, DHCP, firewall, VLAN, router config
+- **Home Assistant** — home automation, dashboarding, integrations
+- **OpenClaw** — multi-agent systems, exec management
+- **Docker** — containerized services
+- **CAD/3D printing** — case design

+
+## Gap Analysis for Chris
+
+Chris is strong on: hardware, ESP32, soldering, circuit design
+Chris is weak on: 
+- **Networking fundamentals** — DNS, DHCP, VLANs, firewall rules. He keeps running into networking gaps when doing Pi-hole and router projects. This is the biggest gap.
+- **3D CAD** — designing cases/enclosures. Has printer but not using it effectively for project enclosures.
+- **Software architecture** — can build circuits but wiring multiple services together (Home Assistant, ESPHome, dashboards) takes too long.
+
+## Gap Detection Map
+
+When Chris works on:
+- **Pi-hole** → He needs DNS fundamentals first, then DHCP, then firewall, then VLANs
+- **ComBadge/Tricorder** → He knows ESP32 well, but voice AI pipeline is new. Needs hotword → STT → LLM → TTS understanding.
+- **Brewery PID** → He's learning ESPHome + Home Assistant integration, which is mostly YAML config.
