I VibeCoded a Platform that Allows you to Practice Mock Interview for Free with Real People

I built a mock interview platform with FAANG engineers. Fully done using Cursor + Claude 3.7 - with a strict policy of 0 logic in JavaScript/TypeScript NextJs and using strict microservice architecture with JVM-based backend. It has over 18,000 users - you can my check the discord if you don't believe me!

Unlike most side projects that think NextJs is the backend framework, I strongly disagree with that. I don't believe anyone can build a truly scalable company without proper backend framework in either Java or GoLang. Most side projects fail because they build in TypeScript/Javascript exclusively.

My competition has built exclusively in Javascript and I am sure they are bleeding money because they are paying for Zoom, CoderPad, other integrations with very limited functionality because it's exceptionally hard to build something in the repo that controls everything from the UI button colors to all logic. I am incredibly happy that in my project, we have over 500 APIs (already!) with super nice, clean, and scalable code. We have our own IDE, Whiteboard, CodeExecution, Voice with WebRTC/SFU, advanced rating & feedback system, our own notification service and more cool things. like RabbitMQ to persist WebSocket messages as well as gRPC apis instead of REST.

For the product itself, I wanted it to feel like a game (I play a lot of chess & counter strike) so I added a queue with match making based on years of experience as well as skill The site was a ton of fun to build and I know this might come across as just an ad but the reason I built it was really to help people and I feel like it will be a ton of help to a lot of you prepping for DSA based interviews. Solving LC questions alone is one thing but solving them while talking through it out loud is another.
