Colin Vaughn — AI infrastructure, systems engineering, and full-stack products

Portfolio LinkedIn Email

Software engineer building auditable AI infrastructure, low-level networking systems, and production web products.

What I build

AI + code intelligence

Persistent knowledge graphs, structural analysis, dependency tracing, and MCP tooling for AI agents.
Systems + networking

Rust and Go services, VPN infrastructure, concurrent workloads, and performance-sensitive software.
Full-stack products

Production React and Next.js applications backed by self-hosted PostgreSQL, Docker, AWS, and GCP.

Featured work

Code intelligence across 30+ languages. Compiles repositories into a persistent knowledge graph for dependency tracing, change-impact analysis, affected-test selection, structural search, and refactor verification over MCP.

Rust tree-sitter MCP Static analysis

Synaptic stars

61.2% lower median global tick time. A NeoForge performance mod that separates distant loaded areas into independently scheduled regions while maintaining 20 TPS across the documented four-region benchmark.

Java NeoForge Concurrency Performance

Tessellate stars

10 relay nodes across four continents. A Rust VPN platform with a Tauri and SolidJS desktop client, WireGuard connectivity, multi-relay routing, QUIC/HTTP3 obfuscation, and a Next.js control plane.

Rust WireGuard Tauri SolidJS Next.js

Visit Tunnely

10,000+ scans for 500+ users. A WCAG 2.2 scanning and browser-side remediation platform with a lightweight ESM plugin providing 76+ DOM accessibility features.

TypeScript React PostgreSQL Docker Puppeteer

Visit A11yCore

A privacy-first desktop AI agent platform built with Rust, Tauri, React, and sandboxed WebAssembly extensions. It explored multi-provider LLM orchestration, a deny-by-default plugin runtime, content-safety controls, and messaging integrations. The repository remains available as a technical reference.

Current work

Full-Stack Developer / Production VPN Engineering at PC Matic

  • Shipping production VPN software and networking infrastructure.
  • Maintaining the customer dashboard after migrating it from Classic ASP to Next.js.
  • Building an unreleased PC Matic project entirely in Go.

Tools I reach for

Rust, Go, TypeScript, Java, C#, React, Next.js, Tauri, Node.js, PostgreSQL, Docker, AWS, GCP, and Linux
