What is it about
Developers take popular tools without understanding why. Need real-time updates? "Use WebSockets." Why WebSockets? What are the alternatives? What problems might we face? Usually you hear something like: "Everybody uses WebSockets for real-time updates. Why should we consider something else?"
That's not how you choose the right tool. You should start with the fundamental question: Does this tool fit our needs? Then consider the team, market, tool maturity, and other factors.
To select properly, you need to understand pros and cons of multiple solutions. If you only know one, you have no choice. And if you think your tool is perfect? You're missing something. Nothing is perfect. Everything has trade-offs. Our goal as developers is to find the best balance—choosing solutions that align with our specific requirements while understanding the compromises we're making.
In this course, I'll walk you through common frontend challenges that appear in almost every project and almost every frontend interview, but remain misunderstood. You'll learn when to use different patterns, which tools to choose, and most importantly: how to think like a technical leader, not just an individual contributor. You'll learn to evaluate trade-offs systematically, select the right tool for the job, and persuade your team that your solution fits the specific goal.
This is for mid-level developers or new seniors preparing for interviews or wanting to level up. These patterns appear in technical interviews and real projects—helping you get promoted, land better positions, and increase your salary. That's what we want, right?
Who is this for?
The Ambitious Mid-Level Developer
You want to move from Mid-Level to Senior
You can build features easily, but you struggle to design the system from scratch
You want to lead technical discussions but lack the confidence to defend your choices
You feel stuck implementing others' decisions instead of making your own
The Senior Role Candidate
You need to ace the System Design Interview
You freeze when asked: "How would you architect this app?"
You know the tools (React, Redux), but struggle to explain why you chose them over alternatives
You want to turn the interview from a "quiz" into a "peer conversation"
