Low Level Design

A practical series on object models, design rules, and the architecture choices that keep systems easy to extend and hard to break.

Available Tracks

Classes, constructors, runtime dispatch, encapsulation, and generics with memory-level labs.

SRP, OCP, LSP, ISP, DIP, DRY, KISS, and YAGNI through refactoring-focused inspections.

Constructor explosion, singleton resource control, and the pattern choices that decouple object creation.

Factory Method, Abstract Factory, and registry-backed creation patterns that keep client code stable.

Telescoping constructors, fluent object construction, invariant checks, and immutable object materialization.
