Freelancer profile translated to English.

Description

I am Jérémie Lukunga, an information systems and cybersecurity engineer with 7 years of experience, specializing in full-stack web development & Java development.

My expertise is built on varied experiences, ranging from customizing web applications for Airbus to solving critical issues in a strategic project for EDF.

On a daily basis, I rely on solid technical skills: JavaScript, Java, Spring Boot, continuous integration with Jenkins, quality management with SonarQube, and relational databases like SQL.

I have applied the Agile/Scrum methodology to collaborate effectively with multicultural teams and ensure quality deliverables within deadlines.

Relevant examples of achievements:

- EDF Switch Project: I designed and deployed an innovative Java module to integrate Wiremock, an HTTP simulation tool, into a secure environment. This solution accelerated simulated tests while ensuring over 80% code coverage.

Methods: Problem analysis, rigorous validation through unit tests, automation of scripts on Linux virtual machines.

- Airbus Project:

I developed and maintained interactive web widgets, optimizing user experience through JavaScript and HTML while ensuring seamless integration with back-end RESTful APIs in Java.

Methods: Continuous deployment with Jenkins, code review via SonarQube, technical documentation to ensure smooth transition.

My strategies include a quality-centric approach, rapid adaptation to complex environments, and enhanced autonomy through constant technological monitoring.

Outside of work, my passion for music, sports, and reading fuels my creativity, teamwork, and perseverance.

I am the competent and versatile technical collaborator ready to transform your challenges into concrete and sustainable solutions.
