FrontendCheck

FrontendCheck bridges the gap between tutorial projects and production-ready SaaS applications.

Most developers learn React or Vue and then build the same todo app that everyone else builds—making portfolios indistinguishable and leaving a knowledge gap when it comes to real-world architecture.

FrontendCheck solves this with structured 10-day challenges that simulate working on a real product team. Each day, you receive an "email" from a fictional colleague with new requirements, architecture lessons, and API contracts to implement.

You'll learn enterprise patterns like multi-tenancy, real-time collaboration, and scalable e-commerce—but instead of building boring generic apps, you choose from creative domains like a "CRM for tracking your exes" or a "fashion marketplace for cats."

The result? A portfolio of unique, conversation-starting projects built with the same architecture patterns used by the production apps you use every day.
