Stop building tutorials.
Start building judgment.
AI writes code. You make the architectural decisions that matter. Learn to think like a senior developer through realistic workplace scenarios where requirements change, stakeholders evolve, and your decisions have consequences.
You can build features.
But can you handle this?
Real scenarios that separate juniors from seniors. These aren't coding puzzles—they're the moments that define your career.
Mid-Sprint Pivot
"Can you add user roles to what you built? We demo Friday."
Your hardcoded auth breaks everything.
Code Review Feedback
"This works, but we'll need to refactor before adding features."
You thought it was done. It wasn't.
Production Bug - 5pm Friday
"The dashboard crashes for users with >100 items."
You didn't think about scale.
Stakeholders Contradict Each Other
"PM wants speed. Designer wants polish. Tech lead wants scalability."
Who do you listen to?
Performance Suddenly Matters
"This page takes 8 seconds to load. Can you fix it by Monday?"
You optimized for 'working', not 'fast'.
Testing Becomes Urgent
"We need tests before we can ship this. You have 2 days."
You wrote code that's impossible to test.
Tutorials teach you to build features.
They don't teach you that every architectural decision is a bet on the future.
This is the gap between bootcamp and professional work.
And most developers learn it through painful mistakes.
The gap between knowing syntax
and thinking architecturally
Tutorials teach you to build. We teach you to decide. Because in the real world, the "how" is easy—it's the "what" and "why" that separate juniors from seniors.
Real Stakeholders
Experience authentic email chains from product managers, designers, and executives. Learn to navigate ambiguity and changing requirements.
Decision Traps
Day 1 choices create Day 5 problems. Learn to anticipate future needs and architect for flexibility, not just immediate features.
Senior Thinking
Compare your solutions to detailed architectural breakdowns showing how experienced developers approach the same challenges.
Progressive Complexity
10-day scenarios where requirements evolve naturally. Experience the pain of poor architecture and the relief of good planning.
Future-Proof Skills
AI can implement features. It can't predict that your client will need internationalization in 6 months, or that this feature will need to scale to 10M users. You can.
Self-Assessment
Detailed rubrics help you evaluate your architectural decisions and understand exactly where you can improve.
Not theory. Not tutorials.
Real scenarios.
Every challenge is structured as an authentic email thread from stakeholders. Requirements change. New information emerges. Deadlines shift.
Just like real work.
The difference? Here you learn from mistakes without getting fired.
Quick thing - legal just told us we need to support
different permission levels (admin, manager, viewer).
Can you add that to what you already built?
Should be straightforward right? We demo Friday.
Thanks!

Hi — I'm Claudia
I've been a frontend developer for 7+ years, leading teams and mentoring dozens of junior developers.
I built FrontendCheck because I saw a pattern: developers could build features, but struggled when requirements changed, code review pushed back, or architecture decisions came back to haunt them.
These challenges teach the thinking process I wish I had when I started. The kind of experience you usually only get after years on the job—and several painful mistakes.
