During this time I managed a large team of 16 Developers , 4 QA’s and 2 DevOps engineers. The organization moved from a developer / operator centric way of working to a DevOps way of working.The first year we have learned a lot about how things work and als how things do not work. Being part of this transition was a valuable lesson.The introduction of new techniques inside the organization for static code analysis and dependency management. You are never too old to learn something and using SonarQube really improves overall code quality.In this year ISO-27001 certification started.

Doing the Performance Management Cycle for 5 developers and one QA. Furthermore be the technical lead of the scrum team consisting of 8 developers and 2 QA’s.During this time we landed a big customer, Sligro Heineken. This made it possible to design a new e-invoicing platform. I was one of the leads for the new platform and I was the technical lead to design the interface between Sligro Heineken and the new e-invoicing platform. This platform is built with the latest technologies and comes close to a micro services architecture. It has been built with spring technologies. An interesting detail is that the invoice design is done by me.The team also started building a CI/CD pipeline. This pipeline is mostly built with Attlasian products.Technologies used:Java , XML , Tomcat , Springboot (Security , Spring data , Sleuth ), Hibernate, Maven , Angular Elastic, Cassandra , ELK Stack , Rest , FOP.Tools used: Jira , Bamboo , Bitbucket , Ansible , AWS RDS Mariadb, AWS SES, Ec2, Docker, Kubernetes , Nexus , IntelliJ, XML Spy, RabbitMQ.Responsibilities:- Manage team of 5 developers and one QA- Do job interviews- Do the performance management cycle- Design and implement new e-invoicing platform- Manage sprint backlog- Perform Agile ceremonies- Implement launching customer on new e-invoicing platform- Coach team members
