Hi! 👋 I'm Max Rozen.

I'm also known as rozenmd around the internet. I'm an ex-Atlassian, and these days I work at Cloudflare, helping build D1.

I run OnlineOrNot, a service that provides status pages and uptime monitoring for websites, APIs, and cron jobs.

I also run this blog on the side, where I write about React, and provide advice that hopefully helps improve your career as a frontend developer.

If you read something here and like it, feel free to share it and let me know!
