Watching an ex-YouTube engineer rebuild YouTube in 45 mins is quite fun. Mikhail (@AstraliteHeart ) spent 8 years at YouTube. When we first met, I asked him how much of it he could rebuild in an hour. He said let's find out. Here's the result. Let's see how much he actually gets done.

🚀 Announcing ByteByteGo Live: learn AI live from real builders. I’ve spent the past 8 years on education: thousands of hours writing books, deep dive newsletters, YouTube, etc. Two issues I keep seeing are: 1) it’s very different to learn from real builders. 2) most online courses never get finished (~4% completion). Over the past 12 months, we’ve been working on what we can do to change that. Today, I’m excited to announce ByteByteGo Live: live cohort courses taught by real builders. - Taught by real builders. Our instructors include very senior engineers from Google, Meta, etc., as well as @KentBeck , the creator of TDD. They teach what they use in their own work. - Live cohorts. Every course runs live with a group of people, and instructors answer your questions in real time. The current lineup: - AI Engineering Fundamentals - Build with Claude Code - Build Production Grade AI Systems - Rebuild YouTube with AI - AI Evals in Practice - AI Cost Optimization - Trust-optimized AI Development We have big plans for the year ahead: more courses, more instructors, and deeper hands on projects. Check out go.bytebytego.com/live-launc… and let us know what you think.

We’ve finished the first draft of a new book and are now looking for technical reviewers. The book focuses on hands on coding interviews and the trends companies are adopting today. The goal is simple. Make coding interviews more practical. More realistic. More aligned with how strong engineers actually think and build. We’re still deciding on the title. If you have a great idea, we’d love to hear it. If you’re interested in reviewing, 𝐞𝐦𝐚𝐢𝐥 𝐮𝐬 𝐚𝐭 𝐡𝐢@𝐛𝐲𝐭𝐞𝐛𝐲𝐭𝐞𝐠𝐨.𝐜𝐨𝐦. A short introduction or a link to your LinkedIn profile would be perfect. Ideally, you could review a chapter or two, so the commitment is small. Thank you for helping us make this book better.

We started a new YouTube channel dedicated to AI fundamentals, infrastructure and models. So far, we’ve published four videos. We plan to publish 1 video every week. Since this channel is new, we’re still shaping its direction and would genuinely love your input. If there are topics you’d like to see covered, please share them with us. Thank you!
