The problem with AI

"I code with AI but I can't explain my code"

You use Copilot or Claude Code daily. But when someone asks why you made that technical choice, you go blank. Recruiters see it. They're testing fundamentals more than ever.

How we help:

Flashcards to anchor concepts

"I know the syntax but not the principles"

You can write React or Spring Boot code. But the virtual DOM, lifecycle, dependency injection? If you need to explain it to a tech lead, it gets fuzzy.

How we help:

Interview questions with detailed answers

"I'm scared of the day I actually get tested"

You keep postponing preparation because it's stressful. But every week without practice is a missed opportunity. Devs who train get the jobs.

How we help:

Simulators under real conditions
