Hello, my name is Cole Ellison

I'm a software engineer with a focus on web performance and frontend platform development.

I recently worked at Grammarly as a DX Software Engineer. Before that, I spent 6 years at Squarespace, rounding out my time there as Tech Lead of Web Performance.

From time to time, I write about my work. and other things I'm thinking about or working on.

• Building simple static sites
• A record of learning (2025)
• Founding a Frontend Platform Group
• Building a cultural awareness of web performance at Squarespace

I'm currently entertaining new opportunities.
