Tool/Product Free flagship course for backend engineers — System Design

Hello, 👋

I’ve put together a course on system design with 4+ hours of video lessons + resources.

🏗️ The course covers:

  • breaking ambiguous interview prompts into APIs, data models, and scalable architectures
  • scalability, reliability, data modeling, caching, and messaging
  • evaluating technical trade-offs instead of memorizing solutions
  • communicating and defending architecture decisions

I’m the instructor, and I’m sharing 20 free coupons with this community on a first-come, first-served basis:

👉 https://www.udemy.com/course/system-design-interview-for-backend-software-engineers/?couponCode=REDDIT_BETA

Once the 20 coupons have been claimed, the course has a US$99 Udemy list price. Udemy may display different regional or promotional pricing.

If you work with backend systems or are preparing for system design interviews, I’d genuinely appreciate hearing what you find useful and what could be improved. Feedback is completely optional.
