Hey, I'm Jonathan 👋

Network engineer with 12+ years in telecoms, former NetBox core maintainer, and compulsive builder of things that should probably already exist.

I run network operations at Metro Optic, own a consulting company, Loop Networks inc., and spend the rest of my time writing open source tooling across network automation, infrastructure, and home automation.

What I maintain & build

NetBox Ecosystem

  • netbox-fms - Fiber management for NetBox. OSP/ISP scope, splice closures,
    cable profiles, high-strand-count fiber. Filling a gap that's been open for years.
  • netbox-pathways - (Coming soon)
  • netbox-peering-manager - BGP peering sessions, communities, routing policies,
    and peer groups - tightly integrated with native NetBox objects.
  • netbox-rir-manager - Live RIR API integration for NetBox (ARIN, RIPE).
  • netbox-cable-labels - Jinja2-templated cable label generation with support for TIA-606-C standard
  • netbox-community/netbox - Former core maintainer. Ongoing contributor - bug fixes, data model work, cable and circuit improvements.

Network & Automation Libraries

  • pyregrws - Python library for ARIN's Reg-RWS API. The one that didn't exist.
  • twamp_exporter - Prometheus exporter for TWAMP/PerfSONAR twping.

Infrastructure & Homelab

  • ipmi-fan-control - PID-based Dell PowerEdge fan control over IPMI. Docker-ready, configurable gains, real-time monitoring.

Home Automation

  • Contributions to Home Assistant ecosystem (Alarmo, ESPHome device support, themes, etc).

Why sponsor?

All of this is built in my own time. Sponsorships let me justify the hours and
keep projects actively maintained rather than slowly abandoned.

If your org runs NetBox in production, peers at an IXP, operates fiber plant,
or manages Juniper infrastructure - there's a good chance you're touching
something I've built or contributed to.

Need something custom?

I'm available for NetBox plugin development, network engineering work,
fiber & OSP data modeling, RIR/ARIN API integration, Juniper telemetry
pipelines, and infrastructure automation consulting. See the tiers.

I can probably also build the app or tool you need where you have the why for but not the how.
