I still remember the moment the lights went on. I rewrote the PaymentProcessor to accept a gateway via its constructor, wrote a fake gateway that just returned a success promise, and watched my tests pass in seconds. It felt like…
A guide to the SOLID principles and the design patterns that put them into practice for building scalable
SRP says a class should have one reason to change. That does not mean one method or one line. It means one job. If a database change, a new JSON format, and a new validation rule all force you to…
বুঝতে ভুল হয়। এই সমস্যার সমাধানই হলো DDD (Domain-Driven Design)। সহজ কথায়, Domain-Driven Design (DDD) হলো সফটওয়্যার তৈরির এমন একটি অ্যাপ্রোচ,...ভিন্ন জ…

was my wake-up call. We often hear about "Clean Code" principles, heavy design patterns, and enterprise-level architecture. But when...ruins readability faster than the "Arrow Anti-pattern"—code that slowly drifts to the right side...that code is still relevant. Clean…
identify responsibilities, model domains, apply SOLID principles, choose the right data structures, and think...Object-Oriented Design and SOLID, why do I need Design Patterns?" It's a great question. In fact,...many developers ask when they first hear about Design Patterns…
