Structured Middle-to-Senior Frontend Bootcamp (Architecture, Scaling, Real-World Systems)
A 12-week, self-paced program focused on frontend architecture, system design, performance, and senior-level decision making
Taught by a full-stack developer with 15 years of production experience and over 10 years of teaching developers.
What This Bootcamp Teaches
- Practice senior-level interview topics through concrete system design and architecture exercises
- Build and analyze complex frontend applications with scalable architecture patterns
- Develop structured problem-solving approaches for unclear frontend requirements
- Learn architectural, performance, and state-management topics typically skipped in tutorials
What Developers Say About the Content
Feedback from emails, YouTube comments, and social media about the teaching style and explanations
What Makes This Bootcamp Different
- Focus on frontend architecture, testing strategies, and scalability trade-offs
- Build a full-stack application from backend to deployment to understand the whole process from start to the end
- All examples and projects written in TypeScript
- Covers both React and Angular through real-world patterns and constraints
- Includes interview-relevant topics such as architecture discussions and decision trade-offs
Is This Bootcamp Right for You?
- ✅ You are a mid-level frontend developer looking to deepen architectural, performance, and system design skills
- ❌ Not suitable for beginners or junior developers without production experience
What You Need to Join
- A Mac, PC, or Linux machine
- Practical experience with React or Angular in production or side projects
