At Naval Group, I work on several strategic projects combining user support, internal application development, and technological innovation.

Internal Application Development- I develop new applications for the group usingXWikiwith integration of **Velocity**, **Groovy (Java)**, **HTML**, **CSS**, and **JavaScript**. These developments allow for the creation of tailor-made solutions adapted to specific team needs.

Technological POC with AI- I designed and developed a complete proof of concept withNext.js(frontend) andNestJS(backend), integratingMistralartificial intelligence. This demonstration aims to showcase the future of Naval Group applications with modern technologies andAIfeatures for conversational assistance and intelligent data management.

Planisware Support and Administration- I provide user support on thePlaniswareplatform for project management, helping teams optimize their use of the tool and resolving daily technical issues.

Utility Applications- I created two practical applications inJavaScript**, **HTML**, and **CSSto improve the daily lives of employees: "**Vendredi**", a rotation manager for weekly breakfasts with team, allergen, holiday, and team anniversary management, and an "**Enterprise Dashboard**" centralizing access to all Naval Group applications with a favorites system, intelligent search, and customizable interface.

This experience allows me to combine technical support, full-stack development, technological innovation, and user experience improvement in a demanding industrial environment.

I worked on the complete redesign of the Frequencies website, an association creating audio fiction for the visually impaired. My mission was to develop an accessible and intuitive platform to facilitate access to audio content, as well as an administration interface for content management.

Development & Accessibility- I implemented a modern frontend architecture withReactandTypeScript**, strictly adhering to **WCAG 2.1accessibility standards. I developed complete keyboard navigation and created reusable components withTailwind CSS**. I also integrated **YouTube**, **Spotify**, and **LinkedIn**APIs** to enrich content management.

Infrastructure & DevOps- I deployed the project onFirebasewhile studying a migration to Azure. I participated in setting upCI/CDpipelines onAzure DevOpsand managed versioning with **Git**, performing regular code reviews.

Technical Leadership- I provided technical direction for the project by training new developers and establishing good development practices. I wrote complete technical documentation and actively participated inagileceremonies as well as architectural decisions. I also produced an in-depth comparative analysis betweenFirebaseandAzureto guide future technical choices.

This experience allowed me to combine frontend development, web accessibility, technical leadership, and DevOps in a project with a strong social impact.

Pokédex Angular- I developed a complete web application for consulting Pokémon usingAngularand **TypeScript**. The goal was to create a more attractive and user-friendly Pokédex than those currently available online, working collaboratively with a designer to optimize the user experience. The application allows browsing all Pokémon with their detailed statistics, types, abilities, and evolution chains. I implemented intelligent pagination with asynchronous loading to optimize performance, and created reusable modular components for better code organization.

I integrated the PokémonREST APIto dynamically fetch data and developed a visualization system for evolutions with automatic information loading. For the user experience, I addedCSSanimations and smooth transitions during navigation. The project usesBootstrapfor responsive design andAngular CLIfor project management.

This experience allowed me to master advanced Angular concepts such as services, observables, state management, and performance optimization with lazy loading. I also deepened my skills in TypeScript and external API integration.

The project code is open source and available for review.
