Real Projects. Real Feedback. Real Growth.
FrontendCheck helps you bridge the gap between writing code that works and building code that lasts. Learn to think like a senior developer — and show you're ready for the job.
Code that works isn't enough.
Most developers can build an app. But few can build apps that hold up to real-world change.
Evolving designs. Shifting requirements. Performance issues. Stakeholder feedback.
That's what separates juniors from seniors.
And that's what FrontendCheck is here to teach you.
Whether you're preparing for job interviews or trying to stand out as a junior dev, this is the missing experience you won't get from tutorials.
How do you become a job-ready frontend developer?
FrontendCheck gives you two paths to level up and get real-world experience that actually prepares you for professional development.
"The best way to learn is by doing. These challenges simulate real-world pressure without the real-world consequences."
Most tutorials show you how to finish a project. FrontendCheck shows you what happens after that.
- On the job, the code is never really “done.”
- Requirements change.
- Clients change their minds.
- Performance breaks.
- Design shifts.
- You’re asked to adapt — and you need to do it without breaking everything.
- Reality Check Challenges are designed to expose bad habits, test your architectural thinking, and help you learn what professional frontend development really requires.


Learn from someone who's been there
Hi — I'm Claudia. I've been working professionally as a frontend developer for over 7 years, leading teams and mentoring junior developers along the way.
I've made my fair share of mistakes, refactored messy code, and learned what truly makes software maintainable and scalable.
I created FrontendCheck because I know how hard it is to make the leap from learning to actually thinking like a professional developer. Tutorials teach you the "how," but real growth comes from navigating real-world scenarios — the kind you only experience on the job.
