Pragmatic System Design Год выпуска: 2025 Производитель: Udemy Сайт производителя: https://www.udemy.com/course/pragmatic-system-design/ Автор: Alexey Soshin Продолжительность: ~5h31m Тип раздаваемого материала: Видеоурок Язык: Английский Описание: Prepare yourself for system design interviews and leverage your knowledge in real-world scenarios with my comprehensive course. Gain the confidence and skills to excel in system design discussions, whether for job interviews or day-to-day work. In today's industry, designing new systems is a rare opportunity for most engineers. Architecture discussions often involve only a select few individuals within companies. However, when it comes to interviews, the expectation is that everyone is a system design master. My course bridges this gap by covering essential topics and providing effective approaches to common system design interview questions. Additionally, this course offers senior engineers an alternative perspective on system design. I encourage open discussions and aim to remove the stigma around imperfect real-world designs. Choose your preferred method of course consumption based on your availability. If you have ample time, follow the logical order of my videos for a step-by-step learning experience, gradually building your confidence. Alternatively, if time is limited or you're not currently actively preparing for interviews, you can start with the design videos. If any unfamiliar topics arise, I provide supplementary videos or links to relevant articles. System design interviews typically evaluate breadth of knowledge first and depth of knowledge second. Thus, I've kept the theoretical portion of each topic concise, aligning with interviewers' expectations. Remember, there's no such thing as a perfect design. Every system involves trade-offs and compromises. Moreover, each design is unique, reflecting your areas of expertise. Approach my videos as a collection of ideas rather than the definitive way to design a system. I value your input! If you have additional system design interview questions or topics you'd like me to address, please let me know. Your feedback shapes my content and ensures its relevance to your needs.
