The microservices module at INFONEXUS is the most comprehensive I've found anywhere. Kafka, RabbitMQ, API gateway — all with real production code examples. I went from a frontend developer to a backend engineer at Razorpay in 5 months. The mock interviews were spot-on.

INFONEXUS's Advanced level Redis and Socket.io modules literally got me the job at Swiggy. My interviewer asked me exactly about Redis sliding window rate limiting — and I had implemented it in class. The system design prep for the Professional level is absolutely FAANG-standard.

I was a PHP developer and had zero Node.js experience. The Basic level's async/event loop explanation was unlike anything I'd read online — it finally clicked. The Docker + AWS Professional module made me a complete backend engineer. Got into Infosys's startup division at 30% salary hike.
