Course Description

Learn to build React projects that stay up-to-date even before they're finished, and discover how to make React applications that are easy to grow and keep up with a system that really works.

If you are exploring this course, chances are high that you’re a React developer looking to level up your skills. In this case, You are in the right place!

The promise of this course is simple: By attending this course you will become the React wizard at your company!

In this course, we touch on unique topics in several modules including, design systems, design patterns, performance optimization, and advanced Typescript with React.

This course explores numerous advanced subjects to guide you in constructing React applications that are maintainable, scalable, and high-performing. It covers topics like scalable project architecture, effective techniques for managing asynchronous operations and API states, advanced component patterns, performance optimization, local and global state management patterns, and more.

If you are a junior or intermediate developer then you will need to master these topics to consider yourself as a senior developer and become ready to apply for senior positions.

All the materials of this course are based on years of experience working on several React projects and every single concept comes with concrete examples.

All the topics are presented with practical real-world examples so you can apply everything in your day-to-day projects right after.


What you will learn:

1 - Advanced Component and Layout Patterns

As a senior software developer, I have identified the topics covered in this module as crucial elements that I seek when interviewing React developer candidates. These patterns can help bridge the gap between being a junior or intermediate developer and becoming a senior React practitioner.

By finishing this part, you'll have the opportunity to explore React's most essential design patterns.

2 - Performance Optimization

Explore many essential techniques for improving and optimizing the performance of your applications to make them blazing-fast and your users amazed - Optimizing Re-renders, Long List Virtualization, Throttling, Denouncing, Code-Splitting & Lazy Loading, and more!

3 - Advanced React Hooks and Concepts

There is also a section about some advanced concepts and hooks and their use-cases as they can help you tackle some challenges in the related scenarios.

4 - Advanced State Management Techniques

Master advanced state management techniques that will allow you to easily manage, share and reuse stateful data in your application. Explore patterns to manage state in a clean, readable and scalable fashion and take advantage of hooks, Immer and Context API.

5 - Scalable Architecture

Learn how to create scalable architecture for your React applications that is actually easy to manage and extend.

6 - Efficiently handle API requests and manage API states at scalable

Learn advanced patterns for managing async operations, API states, and request cancellation by implementing a flexible and scalable API layer and combining it with React-Query.

7 - Design System and Encapsulating Styles

Managing large-scale projects is not just about coding components. Developing endless components without losing track requires solid design systems to guarantee the reusability and maintainability of every element of the project. We will walk you through the concepts and theory, then we develop some basic components in Figma and finally, we build an extensible foundation of design in ReactJS. So you build a mindset of how to design and develop a clean and reusable design system. The greater focus of this module will be on encapsulating styles to guarantee more reusability across your component library.

8 - Clean Code Tips

We also teach you some tips about clean code in React. In this section we explore concepts such As props along with optimizing some performance issues with the Context API.

9 - Advanced Typescript

Last but not least, we explore Typescript the React way! In this module you will learn how to effectively use TypeScript with React components, ensuring that you utilize the appropriate properties. Additionally, discover how to employ the Context API, React Hooks, and type props in order to develop more resilient and type-safe applications on a larger scale!


So long story short, if you wish to tackle all these interesting topics and bring your skills to the next level, then join me in this course!

This course will be under continues progress and more modules will be added based on the students feedbacks!

It hasn't been updated in over a year, and just in the first two sections he is mentioning using create-react-app (deprecated) and styled-components (now in maintenance only mode). I was hoping for modern, updated content. This is a credibility issue. I don't know what I don't know, and now I'm wondering if I can trust what he teaches in the rest of the course.

By Jesus Angeles on 12/19/2025

i was looking for something, to add to my confidence in reactjs / javascript coding. design. this is very very much going to help me. enjoyed the first design pattern - split screen. looking forward to the everything in this course! -- i am now in the middle of the course. i will finish this whole course! its a huge chest of skillset it is going to add to me! very very good course!

By Pratik Mitra on 12/18/2025

It is a very good course for a new learner as well as for professionals, all the advanced react concepts are described in a very good efficient way.

By Thành Kiều Tiến on 11/7/2025

This course provides various advanced knowledge about React that every frontend developer should know to enhance their career. The course could be improved by eliminating outdated implementation of some patterns, which occurs multiple times in different sections, to maintain the consistency. Additionally, the content order should be reconsidered, especially the Typescript section to streamline the learning process.

By Luca Morelli on 8/23/2025

nice course, with a lot of useful material. the only really annoying is a really annoying and out of them css elucubration in the lesson Inline Pattern, similar problem for section 21

By Nelson Jean Pierre on 7/4/2025

It was a great experience. i had the oportunity to learn several pattern design in react. I also learned some techniques related to the perfomance

By Vytautas Božnis on 6/7/2025

I learned a lot of information regarding react and I loved the course but as a note I would prefer it to be split into two separate courses (all of the design system information) and everything else because it's use full to know the tools but it goes to a different place that just react.

By Francescopio Pocobelli on 3/26/2025

Everything was honestly perfect. The only complain I have is not about the Typescript lessons, not cause of the concepts, but I think that the lessons order could have been better, as an example I expected concepts as Interfaces and Types explained before the extends keyword.

By Adrian Soto on 11/11/2024

Great course! This course teaches how to setup some important concepts about performance and optimization. Also contains some good examples about designing and creating custom components. Highly recommend.

By 3211 qwert on 8/12/2024

I am a university student majoring in Computer Science, studying with the goal of becoming a front-end developer in Korea. Your lectures are incredibly inspiring. I love how you passionately explain so much of what you know about React. I also enrolled in your TypeScript course. I’m so satisfied with the quality of your lectures that I’m recommending them to others around me. If you offer a course on Next.js in the future, I will enroll as soon as it’s available. You are truly my teacher. Thank you.
