The Fundamental Principles of Domain-Driven Design (DDD)
Introduction
As software systems grow increasingly complex, it becomes essential to design architectures that accurately reflect business needs. That’s the core goal of Domain-Driven Design (DDD), an approach introduced by Eric Evans in 2003 that places the business domain at the heart of software design.
DDD is more than a modeling method—it’s a design philosophy that deeply influences application architecture by guiding component structure, responsibility definition, and system communication.
This article explores the 10 fundamental principles of DDD, with concrete examples and architectural impacts, especially in microservices contexts.

Work Methodologies in IT – From Waterfall to Agile
For decades, IT project management relied on structured, sequential methodologies, with the waterfall model being the most iconic. This model follows a linear progression of project phases: starting with a detailed requirements analysis, followed by design, development, testing, and finally deployment and maintenance. Each phase must be completed before moving to the next, offering a certain level of rigor and visibility over timelines and costs.

Neuromorphic Architecture: How Brain-Inspired Computing Is Shaping the Future of AI
Introduction: When Computing Imitates the Brain
Since the early days of computing, engineers have dreamed of replicating human cognition through machines. While traditional computers have revolutionized logic, communication, and data processing, they remain fundamentally different from the human brain in structure and behavior.
Enter neuromorphic architecture — a cutting-edge approach that designs computing systems inspired by the biological mechanisms of the brain. Unlike conventional AI, which simulates neural networks in software, neuromorphic systems aim to physically replicate neurons, synapses, and sensory pathways in electronic circuits.

Why Application Architecture Matters in the Digital Age
In today’s fast-paced digital landscape, businesses must evolve rapidly to stay competitive. Behind every seamless user experience and innovative product lies a robust application architecture — the backbone of scalable, secure, and agile systems.
Modern architecture isn’t just a technical upgrade. It’s a strategic enabler of digital transformation, allowing organizations to innovate faster, reduce costs, and deliver better customer experiences.

Introduction
Microservices architecture is a modern software design approach that has transformed how scalable and maintainable systems are built. It’s based on the principle of decomposing a monolithic application into a series of independent services, each responsible for a well-defined business domain. But this decomposition raises a crucial question: how do we define the boundaries of each microservice?
This is where the concept of bounded context, introduced by Domain-Driven Design (DDD), becomes essential. It helps structure microservices around coherent business models, avoiding ambiguity and unnecessary dependencies.
