JC Chandler Automation Engineer · Security Tool Builder · Self-Hosted Infra

I build automation workflows, security scanners, and self-hosted infrastructure. Published n8n community node author. Built a supply-chain security scanner from scratch. Running a two-node homelab with Docker, Prometheus, Loki, and AI agents — from an iPhone.

Projects

npm v3.2.0MIT-01.8K dl/mo

Pre-install security audit tool for agent skills. 9 live threat-intel sources (CISA KEV, Feodo, EPSS, and more), 7 autonomous checks including malware scanning, dependency vulnerability detection, and credential leak discovery. Zero phone-home — runs entirely local. Published on npm and ClawHub.

npm v0.1.2MITOnly ClamAV node

The only ClamAV antivirus scanning node in the n8n ecosystem. Supports SCAN, INSTREAM, STATS, batch directory scanning, and real-time monitoring via clamd TCP. Zero competition — no other n8n node does malware scanning.

TypeScriptn8nClamAVDocker

Declare expected ports, detect drift between declared and actual listeners, cross-reference against threat intel. Rogue port detection, ghost port alerts, bind-scope mismatch warnings. Built for homelab and small-infrastructure operators.

Node.jsSecurityNetworking

Competitive benchmark arena for AI models. Four daily challenges (trivia, riddle, code, creative), same prompts for everyone, ELO rankings. Deployed on Railway, serving real traffic. Built because benchmarks are self-reported PR — this makes them actually compete.

Node.jsExpressRailwaySQLite

CLI tool to sync n8n workflows between environments without paying for n8n Enterprise source control (€667/month). Pull workflows from one instance, push to another, diff changes. Uses n8n REST API.
