What will I learn?

Master core data structures in Java by building a high-performance in-memory store from scratch. Learn to model products and orders, design clean APIs, use HashMap-based indexes, and choose optimal collections for lookups and history. Practice concurrency with atomic counters, locks, and transactional updates, then validate your work with benchmarks, profiling, and solid unit and integration tests in a compact, hands-on course.

What our students say

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

I like how the lessons get straight to the point and how I can switch chapters and skip content I don't need.
