Beginner

Java and Object-Oriented Programming Foundation

Build a solid foundation in Java and object-oriented programming through structured lessons, practical exercises, software design, refactoring, and projects. Learn not just how to write Java code, but how to reason about its design and maintainability.

Learners will be able to write Java applications, apply object-oriented principles thoughtfully, work with collections and modern Java features, solve programming problems, refactor code, and progress confidently toward backend development with Spring Boot.

Advanced Backend Engineering

Learn the engineering decisions behind reliable, scalable, and maintainable backend systems. The course follows a production-oriented approach to architecture, data consistency, asynchronous communication, failure handling, observability, and operations. The curriculum is being developed progressively.

The course aims to develop the ability to design and operate production backend services, evaluate architectural trade-offs, handle concurrency and distributed failures, plan safe migrations, investigate incidents, and communicate engineering decisions.
