The freelancer is one of the top Java experts designing clean, simple, pragmatic software architectures for microservices. He has many years of experience in microservices development. For his clients he mainly uses Spring and Spring Boot but also likes to use modern cloud-native frameworks such as Micronaut or Quarkus. His focus is on the customer and their product. The freelancer supports his customers in delivering stable, highly maintainable software – on time and on budget. To achieve this, the freelancer relies on a detailed requirements analysis as well as a high test coverage with unit and integration tests and static code analysis tools like SonarQube.
The tool consisted of an Angular Frontend and a Java 11 Backend. The freelancer supported the customer throughout the entire process, from the design of the overall architecture, to the implementation and testing of the Java microservices - both through automated testing with Junit 5, as well as end-to-end testing of the rest interface with Postman.
Tools & Technologies
Java 11, Micronaut, Junit 5, Mockito, Assertj, JPA, H2, Postgres, Flyway, Rest, Json, Lombok, Logback, Docker, Kubernetes, Jenkins, Git on Github, SonarQube, Intellij IDEA, Postman
Responsibilities:
Responsible for design, development, test and maintenance of distributed, large
scale resilient systems. Backend / Middleware Development - Mostly SOA Webservices and Batch-Jobs
Tools & Technologies
Java 8, Spring 4, Spring Batch, JPA 2.1, Mockito, PowerMock, Junit, Maven, Sonar Qube
The freelancer is a well known figure in the Java community. He is one of twenty JCP executive committee (EC) members. The EC has the task of deciding which features will be included in the next Java version. Also, Oracle named him Developer Champion. The freelancer is a regular speaker at all over the world, such as Oracle Code One San Francisco, JavaZone Oslow and JBCN Conf Barcelona.
In 2019, he was listed as an "Ubiquitous Gold Speaker" by Heinz Kabutz. Besides this, he works as a technical reviewer for renowned Java books such as Effective Java, Core Java SE 9 for the Impatient, Java by Comparison or the OCP Java SE 11 Programmer II Study Guide.
In 2015, the freelancer started a Java blog and YouTube channel that makes Java accessible to passionate developers. There are many advanced tutorials that you can find online, but tutorials with a solid background like this one are rare. Today, the course is also available at freecodecamp.org and received a total of over 2 million views so far. His free ebook "Java for Passionate Developers" was downloaded almost 20.000 times so far. The freelancer has become well-known in the Java community, with a total of 75 000 followers across various social media platforms. In 2017, the editorial team at jaxenter.com rated him #13 in their list of the world's top Java influencers. Aside from this, the freelancer is co-lead of the Java User Group Munich, as well as a member of the association of the German Java User Groups e.V. (iJUG) and the German craftsmanship community. The freelancer has worked on various Java-related projects since 2001, mainly in the financial and telecommunications industries. In 2007 he graduated with a degree in computer science from the Augsburg University of Applied Sciences in Germany. In 2008, the freelancer successfully completed his Sun Certified Java Programmer certification (SCJP 6.0), of which he is still very proud today. For the freelancer, programming is not just a job, but rather a meaningful, creative craft that he practices every day with joy and passion. Therefore he attaches great importance to the quality of his work. The freelancer believes that while programmers can write 'quick and dirty' code, and deceive themselves that they are saving time and money, doing it properly is worth the initial time and effort. The code will then work reliably and consistently, require less maintenance, and prove to be more economical in the long run.
