- LùklaWeb DeveloperDIGITAL AND ITFebruary 2022 - September 2024 (2 years and 8 months)Bois-Guillaume, FranceAt the Lukla agency, I had the opportunity to work as a front-end developer for SII on a mapping simulation project. This project, developed for Thalès, uses Angular and Electron with Angular Material for the interface, as well as OpenLayers for map management. I developed several interface features, notably a graphical redesign based on the mockups provided by Thalès. I also optimized the rendering of entities to avoid performance issues when changing positions, thus meeting the client's constraints regarding the number of entities in a simulation. I developed the scenario management interface, where I encountered issues with recursive data transformation from their backend.As part of this project, we were a team of 4 to 9 people, using GitFlow and GitKarma, with an Agile Scrum methodology over 3-week sprints. We organized planning poker sessions, manual testing, and an application stabilization phase. Every Thursday, we presented new features to the client and held retrospectives to improve our workflow.Subsequently, I worked for RIVP (Régie Immobilière de la Ville de Paris) as a full-stack developer with a DevOps component. I participated in the version upgrade of a large application portfolio primarily designed in Angular for the front-end and Laravel for the back-end. By containerizing the environment with Docker, I refactored the applications, notably by switching from asynchronous usage to observables, thereby improving data management. I also implemented unit tests and optimized integration using caches to reduce CI times from 20 minutes to 11 minutes, a 45% improvement. My approach is based on respecting best practices to deliver quality service.

Education
- BTS SNIR (Higher National Diploma in Digital Systems Networking and Information Technology)Aforp - UIMM Training Center2019J'ai effectué mon BTS en formation initiale à La Châtaigneraie et en alternance à l'Aforp UIMM, tout en étant employé chez ai3. Durant ces deux années, j'ai appris à concevoir et réaliser des projets dans le domaine industriel grâce à l'école, tout en faisant mes premiers pas dans le monde du web avec l'entreprise. L'un des projets les plus marquants a été l'automatisation d'une ruche d'abeilles. Ce projet passionnant nous a permis de découvrir et d'exploiter la Raspberry Pi. Nous devions y connecter des capteurs pour mesurer la température, l'humidité, ainsi que la quantité de miel produite. Chaque ruche était capable de se connecter au réseau et d'envoyer ses données vers une base de données, où une application web se chargeait d'afficher ces informations en quasi temps réel.
- BIA (Aviation Pilotage Certificate)La Châtaigneraie2016Le Brevet d'Initiation Aéronautique (BIA) m'a permis de découvrir en profondeur l'univers de l'aéronautique, un domaine qui me passionne et dont j'ai toujours rêvé. J'y ai appris l'histoire de l'aéronautique, la réglementation, la météorologie, ainsi que les principes physiques et mathématiques qui s'appliquent aux aéronefs. Dans le cadre de cette formation, j'ai également eu la chance de piloter à deux reprises, une expérience inoubliable.
