Project context:

Taking over and finalizing an internal application allowing students to enroll in exchange programs abroad based on various criteria (grades, competitions, ECTS eligibility, etc.), while providing the administration with a comprehensive tool for managing juries, tracking, and validating applications.

Main achievements:

🔍 Project audit and takeover: analysis of existing code, assessment of progress, and estimation of remaining workload.

🗂️ Functional analysis: study of the specifications and regular exchanges with business teams to refine needs.

🧱 Technical modernization: migration of the backend from Java 8 to Java 21, code refactoring, and performance improvement.

🚀 Implementation of a CI/CD pipeline under GitLab to automate tests and deployments.

🧠 Design and optimization of the application architecture, considering technical constraints and performance requirements.

⚙️ Management of environments (integration, pre-production, production) and deployment monitoring.

🤝 Continuous communication with business teams through weekly meetings to ensure the functional compliance of the product.

Results:

✅ Stabilized, maintainable application compliant with business expectations.

✅ Reduced deployment time thanks to CI/CD.

✅ Notable improvement in performance and code quality after migration to Java 21.
