Description

Zakariae WODDAN, an Engineering and Development specialist in Java with extensive experience in developing complex business applications, system integration, and modernizing digital platforms. A graduate of AIAC, I have worked in demanding environments such as CGI/DGFIP, Avalon Groupe, and CIH Bank, where I was responsible for the design, development, testing, and maintenance of critical solutions using the most popular Java frameworks: Spring MVC, Spring Boot, JPA/Hibernate, EJB/MDB, as well as agile methodologies.

Since March 2023, I have held a key role within RAJA, where I work across the entire B2B e-commerce ecosystem:

backend development on Intershop / Java,

front-end development on React,

API integration via MuleSoft,

event management with Kafka,

deployment and automation on Azure and CI/CD.

Versatile and quality-oriented, I am proficient in distributed architectures, integration flows, UML design, DevOps best practices, and modern industrialization tools (Jenkins, Azure DevOps, Git).

With excellent analytical skills, strong adaptability, and a keen interest in solving technical problems, I am committed to delivering reliable, high-performing, and scalable solutions.
