What we stand for
We’re not here to teach you how to pass interviews. We’re here to help you build the kind of systems that actually run the world. No filler, no fluff — just the raw, messy, hands-on experience that no tutorial will ever give you.
Relevant
No gimmicks — just real-world problems that reflect the chaos and complexity of actual systems.
Hands-On
Skip the theory. Dive into building, debugging, and shipping code that would never pass a whiteboard test.
Unfiltered
We don't sanitize problems. You’ll deal with legacy code, vague specs, and real product constraints.
Frequently asked questions
Have a different question and can’t find the answer you’re looking for? Reach out to our support team by sending us an email and we’ll get back to you as soon as we can.
Why should I practice here instead of on LeetCode or HackerRank?
Because we skip the brain teasers and help you build real-world systems like the ones companies actually use.
Do I need to know system design before starting?
Nope. You’ll learn by doing — not by watching diagrams float across a YouTube video.
What kind of problems will I solve?
Messy ones. With vague specs, evolving requirements, and edge cases — like the real world.
Is this for interview prep?
Not exactly. This is for when you want to actually build things, not just perform well on whiteboards.
Will there be tests or scoring?
Only if it helps you grow. We don’t believe in gamification — we believe in grit.
Is this beginner-friendly?
Yes — if you’re ready to get your hands dirty. No hand-holding, but plenty of real learning.
