This website is a virtual proof that I'm awesome In microservices or any other event-based architecture, in some use cases, a service might require us to make changes to their own local database and also publish an event. That event is then consumed by other services. To have a consistent software system, it is mandatory that these two actions...

Did you know that with PWAs you can create Web Apps that deliver a user experience similar to native apps? Did you know that with the React tooling most of the work to create them is almost done? I will explain how to create PWAs... Mon, 20 Jun 2022 19:00:00 -0400 /2022-06-20-pwa-react/ /2022-06-20-pwa-react/ Here is my second book. Learn how to code applications in React by following a solid path that starts by studying essential JavaScript constructions to then go into React core concepts to finally write an application. Understand how to split an application into components (class or function-based ones), how to...

If you want to know how to design and code an application with Modular Architecture, or with Layered Architecture or with Hexagonal Architecture (Clean Architecture), or with Microservice Architecture this book is for you. If you are a developer...

In this post I will start talking very briefly about general concepts of frameworks....
