Ian Callaghan

Senior web developer since 2012. Spent the last three years building font foundry websites and technologies for The Type Founders. I've now founded Chestnut Software, where I'm building practical SaaS tools and services.

This site is where I document my journey. Thoughts, lessons, experiments, and business ideas as I go.

Launching a new productized serviced - Figma to Astro

I packaged years of Figma to Astro experience into a proper service. Accurate conversion, clean code, fixed pricing.
I Built an Astro Agent Skill for Better Static Sites

I turned years of Astro experience into an open-source Agent Skill that helps AI coding assistants follow best practices automatically.
Starting Chestnut Software

After 13 years building for others, I finally started a company!
