What will I learn?

Master the essentials of building a high-performance credit card authorizer in Java, from ISO 8583 fundamentals and message parsing to low-latency TCP servers and concurrency tuning. You will design routing and authorization logic, integrate simulated issuers and fraud engines, and implement robust error handling, security, logging, metrics, and deployment practices to deliver a reliable, extensible authorization prototype.

What our students say

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without needing to switch platforms... I appreciate everything you do, I've already recommended you to others...
