Principal Infrastructure Engineer · Open Source
Two decades building enterprise and service provider networks — and writing the software that operates them. QA automation frameworks, full-stack web applications, device collectors, terminal stacks across four language ecosystems. When a problem recurs across platforms, I port it — TextFSM lives in Python, JavaScript, and C#; the invoke-shell terminal pattern lives in five implementations. BGP, MPLS, and datacenter fabrics on one side; Python, Go, C#/.NET, and JavaScript on the other.

Multi-Language/Multi-Framework Development
Same problems, solved across multiple languages and frameworks. Every SSH terminal implements the same core pattern — invoke-shell automation with real device compatibility.

Open Source Projects
Organized around the network lifecycle: Day 0 is discovery, Day 1 is inventory and provisioning, Day 2 is operational validation.
Secure Cartography
SSH-based network discovery that interrogates devices via CDP/LLDP to automate topology documentation and diagram generation. Multi-vendor support across Cisco, Arista, Juniper.
VelocityCMDB
Tactical, portable network CMDB with automated discovery, change detection, and operational intelligence. Currently managing 357+ devices across 53 sites.
fibtrace · Forwarding-Graph Analysis
v0.4.0 · MIT · Arista · Juniper · Cisco · Multi-vendor FIB
Visual forwarding-graph analysis for ECMP networks. Collects the FIB from each hop and renders every path a packet can take from source to destination — every ECMP branch, every convergence point, every terminal node — as an interactive graph. Multi-vendor. No agents, no controllers, just SSH and a browser.
What makes it different —
What makes it different —
fibtrace.diff: load a pre-change JSON, load a post-change JSON, see quantified impairment metrics — paths, edges, ECMP width, churn — with a CRITICAL / WARN / OK triage band at the top. Hover any listed path and it renders on both graphs simultaneously — you're not mentally diffing two pictures, the tool is doing it for you. Export JSON for programmatic use, SVG/PNG for MOP artifacts and IR write-ups. Change validation you can hand to a reviewer.nterm-ng
A network-aware SSH terminal that understands what it sees. Sniffer/gutter/parse chain architecture with vault integration and real-time telemetry.
NetHUDs · Network Device HUD
First release 2026 · MIT · Arista · Juniper · Cisco IOS · Linux
Real-time telemetry dashboard for any device with SSH access — no agents, no SNMP infrastructure, no vendor lock-in. One SSH session, one WebSocket, one HTML page, plus an embedded terminal so you never leave the glass. Built for the 90-second "what is this box actually doing right now" view that incident response demands.
What makes it different: the Linux collector probes the host on first connect and only runs collectors whose capability gates are satisfied — same HUD renders different panels for a Cumulus switch, an Ubuntu server, an Alpine container, or a Proxmox hypervisor. Any system that can produce a URL (Grafana, NetBox, PagerDuty, Slack) can deep-link into a live session.

TetherSSH
Go-based terminal on Fyne 2 with gopyte — a custom terminal emulation library. Session management, tree navigator, full alternate screen buffer.
RetroTerm.NET
Retro DOS-inspired terminal in C#/.NET. Modern SSH connectivity wrapped in classic aesthetics.
VelociTerm
Web-based SSH gateway with WebSocket terminal sessions. Enterprise jump host with advanced session filtering.
nterm-qt
Themeable SSH terminal widget for PyQt6 with enterprise features. Embeddable component for building network tools.
gsshpass
Go SSH utility for automating commands. Designed for scripted workflows and older equipment compatibility.
tfsmjs
Re-implementation of Google's TextFSM state machine in native JavaScript — not a wrapper. Full template compatibility, runs in Node.js and browser. Often faster than the Python original.
Personal Projects
Built because problems exist, not because a job required it.
Cross-platform speech-to-text optimized for technical dictation.
Audiobook generator from EPUB using Kokoro speech synthesis.
Teleprompter-style song display for musicians with chord charts.
Whiteboard built with PyQt6 + QWebEngine. Zero CDN, fully offline.
