About Mnoubue

Software engineer specialized in Python, backend, and data engineering, with 6 years of experience, I support companies in the design, optimization, and modernization of their application systems and data flows.

I work on projects with high business stakes, particularly in complex or transforming contexts, where the performance, reliability, and scalability of solutions are essential.

What I can bring you
• Development of robust and performant APIs inPython
• Design of backend architectures (microservices, event-driven)
• Integration of legacy systems (AS400, DB2…) with modern platforms
• Implementation and optimization of data pipelines
• Data processing and analysis (Pandas,SQL)
• Performance optimization (SQL queries, data processing)
• Automation of business processes
• Improvement of software quality (tests, best practices,CI/CD)

My approach

I don't limit myself to development: I take the time to understand your business challenges in order to propose reliable, scalable, and needs-adapted solutions.

I pay particular attention to:
• code maintainability
• system performance
• quality and robustness of deliverables

    During my experience as a Python engineer at Toyota, I contributed to strategic projects related to the digitalization and modernization of business processes on an international scale. My role involved both backend development and the design of robust architectures, with a strong emphasis on interoperability between heterogeneous systems.

    I was involved in analyzing business needs in close collaboration with functional teams, which allowed me to translate complex requirements into adapted technical solutions. I designed and developed backend applications inPython, usingmicroservicesarchitectures and modular approaches to ensure solution maintainability and scalability.

    A significant part of my work consisted of designing and exposing robust RESTful APIs to ensure communication between different systems, including modern platforms and legacy systems such asAS400/DB2. I also participated in setting up event-driven architectures using technologies likeKafkaandRabbitMQ, which improved the resilience and performance of data exchanges.

    In parallel, I worked on orchestrating data workflows with ApacheAirflow, as well as processing and transforming large volumes of data using Pandas. I also contributed to optimizing SQL Server queries to significantly improve application performance.

    I implemented unit and integration tests withpytest, participated in code reviews viaGit, and contributed to standardizing development best practices. This experience allowed me to strengthen my skills in architecture, complex system management, and cross-functional collaboration in a demanding environment.

    Flamanville, France
    Lors de mon expérience en tant qu’ingénieure en développement logiciel chez EDF, sur le projet EPR de Flamanville, j’ai évolué dans un environnement industriel critique où les exigences en termes de fiabilité, de sécurité et de performance sont particulièrement élevées. J’ai contribué à la conception et au développement de solutions logicielles robustes destinées à la section Contrôle-Commande, avec un fort enjeu de qualité et de maintenabilité.

    Mon rôle a couvert l’ensemble du cycle de vie des applications, depuis la rédaction des spécifications techniques jusqu’au développement et à l’optimisation des solutions. J’ai conçu des architectures backend basées sur Python en appliquant les principes SOLID, ce qui a permis de structurer des applications modulaires, évolutives et faciles à maintenir.

    J’ai développé des APIs REST sécurisées, intégrées dans un environnement nécessitant des standards élevés en matière de sécurité et d’authentification. J’ai également participé à la conception d’interfaces applicatives avec Django, ainsi qu’au développement de composants en Node.js et Vue.js.

    J'ai automatisé des processus métiers à l’aide de scripts Python, permettant de réduire les tâches manuelles et d’améliorer l’efficacité opérationnelle. J’ai également travaillé sur l’analyse et le traitement de données avec Pandas et NumPy, ainsi que sur la gestion et l’optimisation de bases de données PostgreSQL et NoSQL.

    J’ai mis en place des tests unitaires avec pytest et participé à la structuration des bonnes pratiques de développement. J’ai également contribué à la mise en place d’environnements conteneurisés avec Docker, facilitant le déploiement et la reproductibilité des applications.

    j’ai travaillé en étroite collaboration avec des équipes pluridisciplinaires , ce qui m’a permis de développer une forte capacité à comprendre des besoins complexes et à proposer des solutions techniques adaptées dans un environnement exigeant.
