With solid experience in developing applications in an Agile environment, I have gained expertise in several key technologies: - Back-End with Spring Boot: Designing and developing high-performance applications using Spring Boot. - Front-End with Angular: Creating reactive and user-friendly interfaces with Angular. - Container Management with Kubernetes: Orchestrating and deploying microservices on Kubernetes. - Teradata Integration: Integrating Teradata procedures and macros, with strong expertise in data management. - Migration Management with Flyway: Automating database migrations to ensure consistency across environments. Code Quality with SonarQube: Monitoring and continuously improving code quality with SonarQube. - Automated Testing with Cucumber: Implementing automated tests to ensure application stability and reliability. - CI/CD with Jenkins and Maven: Automating deployment and continuous integration processes using Jenkins and Maven. - Agile Scrum Methodology: Actively participating in Scrum ceremonies (daily stand-ups, retrospectives, backlog refinement) for effective team collaboration. Run and MEP Referent: - Run Referent: Monitoring the smooth functioning of applications and managing system interactions using tools like Grafana. - MEP Referent: Coordinating production deployments, preparing the Delivery Report (BL), and overseeing production releases. Technical Skills: Spring Boot, Angular, Kubernetes, Teradata, Flyway, SonarQube, Cucumber, Jenkins, Maven, Agile Scrum

During this mission, I developed skills in API Management, test automation, and API security management, all while following an Agile approach. Here are the key points of my experience: API Management Training: Certified 5-day in-person training at Axway University. Agile Methodology: Working in Agile methodology with participation in daily meetings and Scrum ceremonies. Technical Documentation: Writing documentation on the use of Axway Management tool, OAuth 2.0, and SSO based on SAML 2.0, using Confluence and Excalidraw for better understanding and collaboration. Integration Test Automation: Automating integration tests for OAuth 2.0 policies in the API Gateway using a BDD (Behavior Driven Development) approach with CucumberJS and Gherkin. Sequence Diagrams: Creating sequence diagrams (PlantUML) to define the complete mechanism of the OAuth 2.0 protocol and its various flows. Development and Evolution of API Policies: Designing and evolving security and authentication policies for deployed APIs. API Management Technical Support: Providing technical support for virtualizing, securing, and evolving customer APIs deployed on the Axway Gateway. Axway Tools: Using several Axway tools such as API Manager, API Gateway Manager, Configuration Studio, and Policy Studio. Protocols used: Authorization: OAuth 2.0 (Client Credentials flow, Implicit Grant flow, Device Authorization flow, Authorization Code flow, Authorization Code flow with PKCE, JWT Grant flow). Authentication: SAML 2.0 (Security Assertion Markup Language). Technical Skills: API Management (Axway), OAuth 2.0, SAML 2.0, API Gateway, CucumberJS, Gherkin, PlantUML, BDD, Confluence, Excalidraw, Agile.
