System design interviews shouldn't feel like a backend interview with Android added at the end.

As an Android engineer, you've probably designed:

• Screens and UI flows
• ViewModels and repositories
• APIs and databases
• Offline caching
• Networking and synchronization

But Staff-level interviews ask you to think much bigger.

How does the system behave when the network disappears?

How do millions of users affect your architecture?

Where does the source of truth live?

How do you handle synchronization and conflicts?

What trade-offs would you make and how would you explain them?

This course is about learning how to think through those problems, not memorizing architecture diagrams.

4 live sessions · Practical design exercises · Recordings included · Limited first cohort

What you'll learn

01 System Design Foundations

Build a repeatable framework for approaching ambiguous system-design problems.

• Requirements clarification
• Functional vs. non-functional requirements
• Scale estimation
• API and data modeling
• High-level architecture
• Component boundaries
• Identifying bottlenecks
• Making and communicating trade-offs

02 Android Architecture at Scale

Go beyond "MVVM + Repository" and learn how architecture evolves as systems grow.

• Clean Architecture
• MVVM and MVI
• Modularization
• Dependency boundaries
• Single Source of Truth
• State management
• Repository patterns
• Feature architecture
• Designing for maintainability

03 Offline, Caching & Synchronization

Mobile has constraints that traditional system-design discussions often ignore.

We'll explore:

• Offline-first architecture
• Local persistence
• Caching strategies
• Pagination
• Network failures
• Retry strategies
• Background synchronization
• Conflict resolution
• Eventual consistency
• Source of truth

04 Real-World Mobile System Design

Put the framework into practice.

We'll work through realistic problems such as:

• Chat applications
• Food delivery
• E-commerce
• Social feeds
• Ride-booking applications
• Offline-first applications

And we'll focus on the question that matters in an interview:

"Why did you design it this way?"

What makes this different?

This isn't a generic backend system-design course.

It's designed around mobile engineering constraints.

You'll think about:

Network reliability

Offline usage

Local storage

Synchronization

App lifecycle

Caching

Pagination

Battery & performance

Security & privacy

Modularization

Scalability

Because designing a mobile system isn't the same as designing a backend service.

A framework you can take into your next interview

Instead of memorizing dozens of architecture diagrams, you'll develop a repeatable approach:

1. Clarify

What exactly are we building?

2. Quantify

How big does it need to be?

3. Model

What are the data and core flows?

4. Architect

What components do we need?

5. Go mobile

What changes because this is running on a phone?

6. Challenge

What happens when things fail?

7. Scale

What breaks when usage grows?

8. Explain

Why did you choose this design?

Who is this for?

This course is for you if:

✓ You're a Senior Android Engineer preparing for Staff-level interviews

✓ You're moving toward Staff/Principal and want stronger system-design skills

✓ You know Android architecture but struggle with large-scale design questions

✓ Generic system-design courses feel too backend-focused

✓ You want to practice explaining architectural trade-offs

✓ You want a structured framework instead of memorizing solutions

You don't need to be a Staff Engineer already.

If you're a strong Senior Android engineer who wants to grow into Staff-level thinking, this course is designed for you.
