Backend Development Tutorials — Clean Architecture, Performance, Testing

Build scalable, maintainable, and reliable backend systems

Welcome to Backend by Dmytro, a collection of forthcoming guides for backend developers. While there are no posts yet, this site is being prepared to become your go-to reference for writing clean, maintainable, high-performance backend systems using PHP, Symfony, Laravel, and more. Many of the patterns and techniques here apply across other ecosystems, so feel free to explore even if PHP & Symfony aren’t your daily drivers.

What you’ll learn

• PHP & Symfony mastery – real-world patterns from controllers to workers, configuration tips, Doctrine tuning, and testing.
• Clean code & architecture – SOLID principles, hexagonal architecture, ports and adapters, and how to implement them in your system.
• Performance optimization – profiling techniques, caching strategies, database indexing, queues, and asynchronous processing.
• Automated testing – unit and end-to-end coverage so you’re never afraid to improve your code again.
• CI/CD pipelines – GitHub Actions and similar tools to ship with confidence.
• Cloud – deploy to AWS/Azure to keep your system scalable and highly available.
