You are here because system design interviews feel overwhelming

We get it. You're a junior engineer facing interviews that expect senior-level system design skills. The gap feels impossible to bridge. But here's what they don't tell you: The best way to ace system design interviews is to actually get good at system design.

✅ What our members achieve:

• Interview confidence - Walk into any system design interview knowing you can handle whatever they throw at you
• Real design skills - Learn to architect systems like a senior engineer, not just memorize interview answers
• Proven framework - Master my framework - System Design Theory that simplifies any system

• Interview-specific training - Case studies mirror what you'll face in FAANG and startup interviews

Your journey starts here:

📚 System Design-Focused Courses

Why Learn System Design works for interview prep:

1. I focus on what interviewers actually want

Interviewers aren't looking for memorized solutions. They want to see your problem-solving process, trade-off analysis, and communication skills. Our approach builds these exact competencies.

2. Practice with peers at your level

Unlike other resources aimed at senior engineers, everyone here is in the same boat. You'll learn faster when you're not intimidated by decades of experience.

3. Structured learning path

No more piecing together random YouTube videos. Follow our proven progression from basic building blocks to complex system designs.

4. Created by someone who's been there

I have interviewed hundreds of engineers, taught system design at UC Berkeley, and knows exactly what junior engineers need to succeed.
