First Steps in System Design: Designing Backend Architecture That Stands Out in Interviews

I was contemplating how to develop my backend skills as a junior full-stack developer, and this was a very nutritious lecture as I was able to understand the general goals and direction to proceed. Thank you for the great lecture~~

This is a great introductory lecture that taught me what perspective to approach system design from. The materials and explanations were also good as they were made so that anyone could understand them.

While working on projects, I felt the importance of design that considers stability and scalability and have been studying on my own, but the content felt vast and abstract, which sometimes left me feeling overwhelmed. This lecture was a great help in finding direction amid such vagueness. Rather than simply introducing what technologies exist, it first presented actual problem situations that could be encountered, explained concepts centered on solving them, and then pointed out the pros and cons or considerations of appropriate technologies along with each one, making the vague concepts clear to me. Through this process, I came to understand 'why this technology is needed' and 'what problems it's chosen to solve' before the technology itself, allowing me to develop the ability to think about the essence of design rather than being tied to specific technologies. Though it was a short time, it was a valuable period where I could establish direction suitable for my projects and set standards to make judgments and design on my own. I would highly recommend this lecture to those who find design vague or want to learn problem-solving-centered design thinking rather than simple technology acquisition.

This is my first course review. As a job seeker, I believe that with the recent advancements in AI, code implementation has largely become an area that can be resolved. So, as I pondered what would be important, the thought suddenly struck me, "Ah, now it will be important to design systems well, and system design communication will be crucial." Therefore, while reading "Fundamentals of Large-Scale System Design 1," which was introduced in the lecture, just as I thought it would be great if there was a lecture explaining things from a practitioner's perspective, I seemed to have stumbled upon this lecture and purchased it immediately. Personally, it was immensely helpful in grasping the big picture. Even for technologies I had never used but only heard of, I was able to broaden my background knowledge by thinking, "Ah, this could be used in this kind of situation," and I learned a lot about what needs to be considered in the early stages of an actual project. Why did you only appear now...? Not only that, but I also learned how to present projects effectively in an interview as a backend developer. I genuinely find documentation tedious, but from now on, I will diligently document the troubleshooting I've performed. Thank you for this truly excellent lecture. The PPT materials were very easy to read, and I loved the beautifully designed lecture materials! I don't know what other lectures you're planning next, but I will trust and enroll in them :>

It seems like about 3 years have passed since I started working as an architect. Since I've been working according to the domain (manufacturing services), I feel like I'm always approaching system design from a similar perspective, so I'm watching this with the mindset of returning to my original intentions. Especially since I've never designed service-based architectures like e-commerce and fulfillment, your similar explanations have been very helpful. I think it would be great if you could create additional courses on heterogeneous data integration and real-time processing (multithreading, GPU acceleration, etc.) as additional services, since these are being used a lot in the manufacturing (energy) sector these days. Also, if you have the opportunity, I think uploading content about vector database design, which everyone is interested in these days, would be very helpful for job seekers. These days, even manufacturing-based SI group companies are looking for new hires who don't seem like typical new hires. Thank you.

This is really amazing....

I spend a lot of time thinking about how to build systems well, and this helped me establish direction on both the fundamental concepts and how to study going forward. It was a very beneficial lecture.

This is a course where you can learn broadly, even if not deeply. If a next course comes out that covers more difficult content, I'd like to take it!
