Architecture

Most Spring Boot projects start in a very similar way:

• Controller layer
• Service layer
• Repository layer

The @Transactional annotation is one of the most useful features in Spring Boot applications.

In microservice architectures, REST calls between services are unavoidable.

However, one of the most common and dangerous production mistakes is forgetting to configure proper timeouts for REST clients.

Exception handling is a fundamental part of application design, yet many systems — especially legacy enterprise codebases — still rely heavily on checked exceptions and extensive try-catch blocks across every layer.

In modern microservices architectures, this approach often causes more harm than good.

In distributed systems, logging and exception handling are not just debugging tools — they are core parts of system reliability and observability.

Poor logging makes production issues hard to diagnose, while improper exception handling often leads to hidden failures, inconsistent states, and frustrated users.

Welcome to the articles section.

Here you’ll find practical, experience-based content about real-world software engineering — focusing on what actually works in production and what often goes wrong.

The main topics include:

• Common programming mistakes and hidden pitfalls
• Software architecture and domain-driven design
• Microservices and distributed systems
• Backend engineering with Java, Rust, Go, and Python
• DevOps and IT security topics

The goal is to share clear, actionable insights based on real enterprise and production systems — not just theoretical concepts.
