Building PRISM: A hands-on playground for system design

Hey everyone! I'm building PRISM, an interactive playground for system design.

I wanted to build something beyond videos and architecture diagrams — a place where engineers can design systems, simulate traffic and failures, discover bottlenecks, and understand why their designs break.

With PRISM, you can practice system design interview questions, experiment with your own architectures, fix failing systems, explore production-grade designs, and prepare with AI-powered mock interviews.

We're still early, and I'm building PRISM to make system design more practical and hands-on for engineers.

If you're learning system design or preparing for interviews, I'd love for you to check it out and share your honest feedback!
