Pass the system design interview. Then lead technical decisions at work. That's architecture thinking. And that's what this course teaches.

"Those are very rare and the frontend landscape could really catch up with the principles Dmitrii teaches, especially thinking in terms of systems and architecture.
The Pre-AI Era
The role was about code output, framework expertise, and memorized docs.
The Post-AI Era
Success means designing systems and managing trade-offs. You are the pilot.
"I'm really enjoying the course so far — there's a lot of value in it and I'm learning a ton.
