The Skill AI Can't Replace.
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 Code Writer
The role was about code output, framework expertise, and memorized docs.
The Post-AI Era
The System Architect
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.
The Decisions AI Can't Make For You
Every module teaches you to make — and defend — a specific architectural decision.
How to structure your app?
Vertical slices, feature folders, scalable architecture for teams.
How to avoid chaos in large apps?
Code organization that scales without becoming a mess.
Which framework?
How to evaluate React vs. Vue vs. Svelte based on team size and constraints.
How to manage state?
When local state is enough, when to add Zustand, when Redux makes sense.
REST or GraphQL?
Trade-offs of each approach and how to choose for your project.
How to handle real-time?
Polling vs. SSE vs. WebSockets — and what breaks at scale.
How to paginate?
Offset vs. cursor vs. keyset — performance implications explained.
How to test?
What to test, what to skip, how to build confidence without wasting time.
How to deploy?
CI/CD patterns, deployment strategies, rollback plans.
