Linux is an indispensable tool in the world of software development. In my blog post, I show the importance of Linux in software development. I go into the Linux file system, the differences to Windows, and basic commands such as cd, mkdir, and rm and give an overview of authorisations.

The Java language and JDK ecosystem are full of hidden gems. In order to find them, you have to take a closer look at different JDK Enhancement Proposals (JEPs). In this blog post, I will take you on a journey of discovery where you will learn about code snippets in javadoc and find out how to make an application start more quickly with the help of AppCDS.

Services have to inform each other about important business events, such as price changes or order events, in microservice architectures. These integration events are transmitted using methods such as message queues or HTTP POST requests. Guaranteeing consistency is critical to ensuring that events are only dispatched if the business logic in the sending service is successfully completed. The ‘event store’, which was inspired by Vaughn Vernon, does just that. In my blog post, I describe an implementation scenario involving Java using Spring and Spring Data JPA, where Spring application events play a different role than integration events.

AWS DynamoDB is a high-performance NoSQL database service designed to serve as a key-value store. As a fully managed, serverless service, DynamoDB offers a fast, flexible and cost-effective way to store and retrieve data in the cloud. In this blog post, I take a deep dive into the main features, design patterns and best practices relating to DynamoDB.

Keycloak is an open-source platform for identity and access management (IAM). It offers extensive functions for secure authentication, authorisation and user management for modern applications and services. I will show you in this blog post how a customer number can be implemented as an additional login feature alongside user name and/or e-mail address.

Is writing unit tests in Jest part of your day-to-day routine? If you are already familiar with Jest, then you are probably adept at using all the basic functions. But when was the last time you really took the time to explore Jest and all the features it has to offer? We might just have one or two features that you were previously unaware of that will make your daily work easier.

In this blog post, I will provide a brief introduction to the fascinating world of the Rust programming language that I hope will spark your curiosity. Rust is a system-level programming language that focuses on performance and security. It is ideal for a variety of applications, ranging from system programming to web development.

I learnt how to evaluate candidates in the Angular domain in recent years. During that time I noticed that there are no standardised certifications. As Angular is constantly evolving and requires a broad skillset, I am planning to create a guide used to evaluate developers consisting of three levels – junior, professional and expert – as a more objective way to assess candidates. The minimum requirements for each of the individual levels are described in this blog post.

Micro-services have long been the established standard in backend application architecture. They offer many advantages, including scalability, flexibility and when it comes to organising large projects into independent development teams. In this blog post, I will describe how micro frontends allow you to transfer the benefits offered by distributed systems over to the frontend.
