Problematization is a term that can be translated as "raising a problem" or "problem framing." It can also be interpreted as problem setting or problem definition. It is a concept that involves questioning known facts—such as requirements or common sense—from a new perspective, defining the problem, and structuring the process to solve it. While problematization should be the starting point for all development, it is a topic that has not yet been sufficiently discussed in the field. Carrying out a project or developing a program is, in fact, the act of creating a plan to solve a problem. In other words, it is inherently linked to problematization. To solve a problem, the problem must first be clearly defined. However, most problems are given in the form of vague requests. Therefore, having the power to transform vague requests into clear problems can reduce unnecessary "development waste," facilitate smooth collaboration, and accurately identify the true needs of users. This course helps you train your "constructive thinking" regarding problems through practical cases and tools.

You may have felt frustrated using Redis without being able to explain why it should be designed that way or why certain patterns emerged. Through my experience in both practical development and as an interviewer, I have treated Redis not just as a simple cache, but as a core component that determines service stability and scalability. This course is not about memorizing commands; instead, I will share my experiences on which structures to choose in real traffic environments and their trade-offs, helping you establish the criteria to explain these concepts confidently in both interviews and practical work.
