Badr Achir

Holding a master's degree in computer science, I have over eighteen (18) years of experience in software development, as a functional analyst and analyst-programmer. My diverse and in-depth training in analysis, architecture, design, and programming enables me to effectively manage large-scale projects. I possess strong skills in Object-Oriented Java, .Net, C, and C++.

I have excellent expertise in application integration with the Spring Boot framework and MuleSoft middleware. I also have strong expertise in designing and automating CI/CD pipelines via Jenkins, ensuring smooth build, test, and continuous delivery processes for Spring Boot microservices and MuleSoft integrations. I also have significant experience with distributed applications, particularly with platforms such as Apache Kafka, Apache Storm, and the Elasticsearch search engine.

Additionally, I am proficient in developing and deploying cloud services, especially on OpenShift. I also have expertise in big data systems, particularly in data specification and modeling with Apache Storm and Databricks. My various roles have allowed me to enhance my technical skills and have greatly contributed to my personal development, strengthening my passion for teamwork.

I enjoy taking on new challenges, I am versatile and open to learning new technologies. I possess strong technical skills and excellent analytical abilities. I am rigorous, dynamic, autonomous, punctual, and motivated.
