I develop Analys'on, a tool for technicians responsible for the cathodic protection maintenance of pipelines at Natran (formerly GRTgaz). The project has significant challenges: it has undergone several unsuccessful attempts, and the current tool satisfies neither management nor technicians. I am involved as an Angular front-end developer, in direct contact with Functional Analysts and the Product Owner, to integrate Figma mockups and challenge functional requirements. One of the major challenges is performance optimization for large volumes of data, through the integration of dependencies like Ag-Grid and the development of custom practices (caching, virtual scrolling, pagination). The stack is modern (Angular 21, Java 21, Spring 3, Signal Store NgRx), and the project is part of Natran's AI integration initiative (Claude).

I supervised a first-year cohort as a developer trainer during the second block of their program, focused on making them operational for their first professional experience. The audience consisted of adult learners retraining for a career, whom I guided on a core project enriched weekly with new concepts, techniques, or tools. I was present in person 2 to 4 mornings a week, supplemented by video conferencing sessions from March 2026. While the overall educational program was defined by Ada's pedagogical team, I organized my own sessions: designing workshops, leading the mornings, and adapting the content to the cohort's pace. Topics covered a broad spectrum: Java, JavaScript, TypeScript, SQL, object-oriented programming, Podman/Docker, Angular, REST APIs, design patterns, TDD, and JWT authentication. I also touched upon complementary concepts such as Keycloak, accessibility, GraphQL, and functional programming.

Participation in the migration of the FRET portal (satellite imagery ordering) to Angular Material MDC.

Refactoring of components, harmonization of the design system, and mentoring an intern on Angular best practices.

Results:

- Smooth migration without functional regression

- Modernized interface compliant with the Airbus design system
