Hey Android developers! 👋
I’m thrilled to announce that our Android System Design Roadmap is now live on our website. This is a complete, structured curriculum that maps out everything you need to master to ace system design interviews and build production-scale Android applications.
Why This Roadmap Exists
Let me be brutally honest: most Android developers can build apps, but struggle with system design interviews.
You know the drill. You’ve built production apps. You’ve shipped features. You understand Kotlin, Jetpack Compose, and all the modern tools. But then you walk into a FAANG interview and hear:
“Design Instagram for Android.”
And suddenly, you’re not sure where to start. Do you talk about the feed algorithm first? The caching strategy? The architecture pattern? How do you structure 45 minutes of discussion to show you actually know what you’re doing?
This roadmap gives you the exact path to follow.
What You’re Getting Today
We’ve just released the complete curriculum - a meticulously organized list of topics, modules, and learning objectives that covers everything from Android OS internals to designing apps like Instagram, Uber, and Netflix.
Think of this as your master blueprint for Android system design mastery.
📋 What’s Included Right Now:
✅ 18 Comprehensive Modules covering 30 weeks of structured learning

Who Is This For?
✅ Perfect For:
Mid-Senior Android Developers (3+ years) preparing for FAANG interviews
Android Engineers looking to level up to Staff/Principal roles
Mobile Architects wanting to formalize their system design knowledge
Career Switchers moving into Android from other platforms
Self-learners who want a clear, structured path
❌ Not Ideal For:
Complete beginners (you need Android fundamentals first)
Anyone looking for quick tips and tricks
Developers who just want to build simple apps
How to Use This Roadmap
Here’s my recommendation for getting the most out of it:
🎯 Option 1: Follow the 30-Week Timeline
Start from Module 1 and work through systematically. This is ideal if you’re:
Preparing for interviews 6+ months out
Want comprehensive coverage
Building strong foundational knowledge
⚡ Option 2: Focus on Your Weak Areas
Jump directly to modules where you need improvement:
Struggling with architecture? → Module 2
Need performance skills? → Module 4
Preparing for interviews? → Modules 13-17
🏃 Option 3: Interview Sprint (8-12 Weeks)
If you have an interview coming up:
Week 1-2: Review Module 2 (Architecture Patterns)
Week 3-4: Module 3 (Networking & Data)
Week 5-6: Modules 7-10 (Real Applications)
Week 7-8: Module 13 (Interview Framework)
Week 9-10: Module 17 (Real Interview Questions)
Week 11-12: Practice mock interviews daily

A Personal Note
I know exactly how overwhelming it can feel to prepare for system design interviews. There’s so much to learn, and it’s hard to know where to start or what to prioritize.
That’s why we created this roadmap - to remove the guesswork.
You now have a clear, structured path. Every topic you need to know. Every skill you need to develop. Every question you need to practice.
The roadmap is here. The path is clear. Now it’s up to you to walk it.
And remember - having the curriculum is already a massive advantage. Most developers are learning randomly, without structure. You now have the blueprint that successful candidates follow.
Start today. Study consistently. Practice deliberately. And you’ll be ready when that interview invitation arrives.
