I keep hearing, “You MUST start with a monolith.” Every new project? Always? When I hear that, two thoughts immediately come to mind:      1️⃣ “It depends.” You can’t just blindly say every project must start as a monolith.      2️⃣ My inner Dushnylo whispers: “Time to make a post about this.” So, here’s my take: I disagree. Not only do I disagree, but I believe the most critical and dangerous part of system design is analyzing and understanding business needs before making architectural decisions. Why? Simple. Imagine you’re building a streaming platform that processes massive amounts of data, handles notifications, and integrates with third-party services. Does this sound like something you’d build as a pure monolith? Of course not. But I do agree on one thing—you have to start somewhere. That starting point could be a simple core application —yes, it might look like a monolith at first. But you’re not designing the entire system as a monolith. ...

Introduce My next post is about tools for managing roles and dynamically controlling access to resources. Some business requirements demand extreme flexibility, often requiring a combination of RBAC + ABAC at the same time. From my experience, I’ve seen a lot of solutions, but most don’t cover all the key points. There are three circles that are really hard to combine: Performance, Security, and Flexibility . And when someone tries to implement all three—oh, it’s painful. But I found a technology that (almost) solves this challenge: Cerbos —a scalable, open-source authorization layer for handling roles and permissions. ( Cerbos site ) Why is it good? ✅ Centralized configuration – Everything is managed in one place. ✅ Easy integration – SDKs are available for all popular languages:     🔹 .NET, Go, Java, JS, PHP, Python, Ruby, Rust ✅ Great documentation – Clear examples and guidance. ✅ Playground for testing – No need to run an app or set up tools. Just te...

  Exploring RavenDB: First Impressions and Key Features 🚀 At the recent conference ( https://devworldconference.com ), I was impressed by the possibilities and feature set of RavenDB. It’s not just another NoSQL database—it delivers on its promises with ease of use, powerful features, and high performance. In this post, I’ll share my first-hand experience with RavenDB, highlighting its key features, what makes it stand out, and my thoughts after testing it in a real-world pet project. Let’s dive in! 👇 List of features: Database Management Studio & Open-Source NoSQL Document Database – Ease of Use It's not just a slogan—it’s true. It took me around 5 minutes to run RavenDB and its Database Management Studio on my laptop. You can start experimenting with this DB locally in just a few minutes, without digging through tons of tutorials or manuals. No need to install dozens of tools and subsystems—just a few minutes, and you have a full sandbox for exploring and learning everyt...
