I'm excited to be here learn and collaborate with all the talented engineers here. 😊

Hope you guys are having a great weekend! Just wanted to give you a quick heads up that I'll be flying around Europe Dec 2-4. Nothing changes for the group calls, we'll have the 2 calls next week. For next week's 1/1 syncs, hit me up either tomorrow (Monday) or end of the week. During my flights I'll be slower to respond. PS. Let me know if you're around any of these cities in December, I'm down to meet up: Bari, Milan, St Moritz, Zurich, Paris

Just updated the plan for our December group calls. We’ll be covering a bunch of interesting topics including AI assisted development, MCP servers, examples of the Production RAG systems, mock system design interviews and more. Check the calendar for more details. Curious to know which topic interests you the most? 👇

This week we did a role play system design interview where we designed a messaging app similar to WhatsApp. If you want to revisit anything, the full recording is below. Next week I’ll upload a longer, more detailed version of this breakdown so you can see the full design process step by step and compare it with your own approach. PS. what would you like us to work on next? 👇

Last week, we role-played designing a chat system like WhatsApp from scratch. Today I also published my version of designing such a system and discussing the trade offs, scaling phase, disaster recovery, etc. Grab a cup of coffee and enjoy as it's 1.5h long 🙂
