In February I started working on a SpringBoot Springboot Microservice project at Discovery
Curro Schools For that year, I wore two hats: 1. Software Dev Best Practices Coach - Completed 6 POCs and wrote a Spring Boot Microservice to publish messages on the RabbitMQ server: https://github.com/nic0michael/RabbitMQProducerMicroservice using Industry Best Practices. - POCs: 1. Writing Microservices using TDD (Test Driven Development). 2. Two ways to “Dockerize” a microservice with a Docker file and with a Docker Compose file. 3. Writing Microservices using BDD (Behaviour Driven Development). 4. SonarQube quality analysis: - How to find and fix bugs using SonarQube. - How to customize the Quality Gates and severity levels. - How to run SonarQube as a Docker Container. 5. Using Portainer to manage and launch dockerized projects. 6. Using Postman to do automated integration tests: - Trained testers and developers to use Postman for writing automated test suites. - JavaScript test script creation and running tests from the Postman Test Runner. 2. Senior Java Developer - Worked on Vaadin web application and wrote Spring Boot Microservices.
