I listened to the lecture carefully. The technical content was explained in a friendly and easy-to-understand way, so it felt like a skilled senior was teaching me. Personally, I had a few regrets. First, the sound was too low and the sound quality was not good, so it was difficult to listen to the lecture. There was a lot of explanation about the API specifications, but I felt it was unnecessary for me. Instead, I wish there had been a more in-depth explanation of system design methodology and scaling. In such cases, what components can be considered, what are the advantages and disadvantages of each (although it was explained in Section 2), and what problems and improvements might arise during actual use. Despite this, it was a lecture that I learned a lot from. The instructor said that he would continue to update the lecture and lecture materials, and that he would improve the lecture quality by using a high-quality microphone in the future, so I look forward to it.

It was great to learn how to design systems to solve complex problems through various corporate cases! It was fun to learn concepts with examples, and I could understand in which situations the concepts would be used. Visualizing the design with Excalidraw was also a great help in learning! Thank you for the great lecture.

The secrets of system design at Silicon Valley Big Tech. Learn distributed systems, DB, scaling & interview preparation in a practical way through case studies of Tesla FSD, Netflix streaming, and Meta infrastructure.
At the end, you'll design your own service and complete everything from SLO quantification → architecture → data model → scaling.
Outstanding work will be featured as a reference on Thread(3.6K+)/Substack(400+), serving as strong evidence for your portfolio/resume. If desired, your LinkedIn/resume link will be included → becoming direct evidence to recruiters
Through interviewing with various US big tech companies like Apple, Meta, Tesla, and Snapchat, I deeply realized that these American global companies are organizations that handle terabytes of data and constantly think about their users. As a result, the bar has been raised for US global companies to evaluate 1,000 or even 10,000+ resumes, and algorithm and system design capabilities have become crucial.
Additionally, those who are currently working on side projects alone will be able to proactively determine what kind of system design would make a good portfolio.
Through small group training with engineers from various big tech companies like Apple, Google, Netflix, Meta, and OpenAI, pair programming and discussion-based classes with talented individuals from the US, India, China, and other countries, I received education in curricula such as system design, algorithms, frontend, DB design, OOD design, and more. Based on my experience interviewing with companies like Apple, Tesla, and Meta, I created this hands-on course based on actual systems. By sharing this with you, at a time when the US and China are engaged in an IT war over AI supremacy, I aim to use this course as a stepping stone to empower engineers in the US, China, and Korea alike—not to be engineers who merely adopt recipes, but to understand the core essence and be able to implement new things. This is the vision and purpose of this course.
- Global Service Design
- Netflix, Tesla FSD, Spotify, CI/CD pipelines, etc.
Based on real-world cases, we deeply cover "how it was designed and what trade-offs were chosen."
- Database & Object-Oriented Design
- RDBMS vs NoSQL, sharding/indexing, cache strategies, and OOD design principles
Practice with real-world examples.
- Machine Learning System Design (NEW)
- Using Tesla FSD style pipeline (training→deployment→monitoring) as an example
Explains the architecture for deploying ML models to actual production.
- Large-scale Traffic Scaling & Failure Recovery Design
- LB, CDN, MQ, Redis/Cache, Blob(S3), WebSocket, Proxy, Telemetry, etc.
Structure it to a level that can be explained in interviews.
- Ongoing Q&A / 1 Year of Additional Learning Materials Support
- Feel free to ask questions about system design even after completing the course
- FAANG and US/domestic company interview preparation scenarios and algorithm content 1-year membership provided free
Provides FAANG or US AI companies / Korean top-tier companies interview questions and interview strategies
Practical scenario-based system design and algorithm content

Hello, thank you for your review. We are currently waiting for a microphone with specifications such as noise cancellation to improve the quality of the lectures. 😭 We will update the quality of the lectures and the quality of the lectures by reflecting the contents you wrote in the review from mid-January. Thank you again. We will continue to work to create better quality lectures in the future.

The lecture content is really good, but... you say "uh" too much, so it's really distracting to listen to the lecture.
Thank you for your good feedback. I tried to fix it in the algorithm lecture. I plan to gradually update the lecture to a version without uh in the future. Thank you for taking the lecture, and I will repay you with a better lecture in the future.

Thank you for creating the course. It was great to get a taste of the architecture of various services. The content is good for beginners who are new to system design. Overall, the only downside seems to be the delivery. The delivery and editing were not smooth, making it difficult to concentrate. It would be good to cut out unnecessary parts through editing. I hope you continue to create good content in the future. updated: I thought the first two sections were fine. The schema and OOP system design parts were a bit lacking. It would have been helpful to show the overall interview picture or outline before starting and say, "It's good to talk to or ask the interviewer about these points here." Still, I'm very grateful that you seem to be constantly revising the course :)
Could you provide a specific example of what was ambiguous, overly simplified, or lacked clarity? Were the component concept lectures updated, and was the system design lecture lacking in comparison? In cases where concepts were explained earlier, I briefly skipped over some things due to the 45-minute time constraint to maximize time for the Big Tech system design interview. Thank you for the feedback.
Thank you for your update feedback. I will continue to improve and make it a better lecture.
