Engineer by trade,
nerd by nature.

I'm Aaron — a Principal Engineer who's been writing code since before most people had internet. I grew up in Alaska, where long winters and dial-up connections gave me plenty of time to fall in love with programming.

These days I'm based in North Carolina, working deep in the domain industry — the infrastructure that keeps the internet's address book running. I care about systems that are elegant, resilient, and fast.

When I'm not architecting solutions, I'm probably tinkering with side projects, reading about compilers, or explaining to people why domain names are actually fascinating.

Things I've Built

A selection of work spanning domain infrastructure, tooling, and the occasional passion project.

Domain Registry Infrastructure
Infrastructure

Registry Platform

Core backend systems powering domain registration, DNS resolution, and WHOIS at scale. Built for reliability and millions of daily queries.

DNS Tooling
Developer Tools

DNS Diagnostic Suite

Internal tooling for debugging propagation issues, zone file validation, and real-time DNS health monitoring across global nameservers.

API Platform
API Design

Registrar API v3

Redesigned the public-facing registrar API with RESTful principles, improved auth flows, and comprehensive developer documentation.

Automation Pipeline
Automation

Ops Automation Pipeline

Eliminated hours of manual ops work with a custom pipeline for certificate renewals, zone updates, and compliance reporting.

Unstoppable Domains CLI
CLI · TypeScript · NPM

Unstoppable Domains CLI

A fully-featured command-line tool to manage your entire domain portfolio without ever touching a UI. Search, purchase, and manage domains directly from your terminal. Written in TypeScript and published on NPM for a one-line install.

DNS MCP Server
AI · MCP · DNS

DNS MCP Server

An MCP (Model Context Protocol) server that bridges traditional DNS infrastructure with AI assistants — enabling LLMs to perform real DNS lookups, query WHOIS/RDAP, and reason about domain data natively inside AI workflows.
