Why I’m Doing This
Over the past months, I’ve shared a few videos on frontend system design — things like state management, data fetching, pagination, and optimistic UI.
They got a lot more traction than I expected. More importantly, I received really thoughtful feedback and questions from many of you.
That made me realize: there aren’t many good resources that go deeper into frontend system design. Most material out there is about backend architecture, or it only scratches the surface on frontend.
So this course is my attempt to fill that gap.
Why a Presale?
I want to build this together with an initial group of learners — people who care about the same problems I do.
If enough of you (32) join, I’ll proceed and finish building the full course.
If not, I’ll refund everyone, no risk involved.
And since you’re reading this here, you get the lowest public price: $79 (instead of
$119).

What You’ll Learn
This isn’t about just making components work. It’s about learning to think like a frontend architect — someone who can design apps that scale, stay reliable, and perform well in the real world.
The course will cover the following essential areas:
The clear roadmap for learning Frontend System Design
Data modelling & state management in depth
Data fetching & caching
Data mutation & real-time updates
Rendering strategies (CSR, SSR, SSG, streaming)
Performance optimization
Infrastructure & cross-functional needs (accessibility, error handling, CI/CD)
And you’ll tie it all together in a capstone project: a Trello-like app that’s production-ready and resilient.
Why Now
With AI writing more and more of the boilerplate code, what makes a developer valuable isn’t just knowing syntax or APIs — it’s being able to design systems.
That’s what this course is about: helping you build the mindset and techniques to think at that level.
Only 32 seats in total — once we hit that number, the presale will close immediately.
Joining now means you’ll not only secure the lowest price, but also help shape the course as it’s being built.
