Experience

Comparateur Location Utilitaire

https://comparateur-location-utilitaire.fr/

A car rental comparison platform. I worked across the full-stack and contributed to both integrating third-party APIs (Hertz, SIXT, Enterprise) into a Node.js proxy that parsed and sorted offers for the web client, and implementing map monitoring on the result page using React. The website benefited from high search performance paired with good referencing and was ultimately purchased by Free2move (Stellantis).

Scalable Data Architecture for a Transport Management System

As the client encountered latency issues that undermined operational efficiency, they aimed to resolve escalating data complexity and modernize their workflow. I led the structural redesign of the system and initiated a data migration process toward specialized databases. I also introduced streaming data processing pipelines, empowering near-real-time synchronization across the system. Transitioning from a monolithic to a loosely coupled, polyglot architecture boosted data access performance by over 50%, while significantly enhancing the system's maintainability and scalability for future growth.

LaboModerne eCommerce Platform

https://www.labomoderne.com/

I contributed to an eCommerce platform serving the distribution of scientific instruments to laboratories and industrial clients. I worked across the full stack, designing reusable components for the product catalog and shopping cart and enabling real-time notification updates for them. I also implemented and configured Meilisearch indexing for the website's search engine.

Search Engine for Lutam

https://lutam.fr

Lutam is a vehicle rental company operating multiple agencies across the Alps. They needed a flexible search experience integrated into their WordPress website, along with better internal tracking of rental offers. I built a customizable search engine as a reusable web component for seamless CMS integration. I also developed a back office coupled with a PWA to centralize offer tracking and streamline in-agency validation.

Supply Chain Traceability Platform

Early in my career, I built a blockchain-based supply chain tracking system from scratch. This included a real-time dashboard for companies to monitor their supply chain and a QR code tracking mobile app for end consumers. I worked extensively with Hyperledger Fabric for the blockchain layer, Google Maps API for geospatial tracking, React for the dashboard, and React Native for the mobile application.

Decoupling and API Design for a Music Distribution Platform

https://www.nudacy-records.com/

Nudacy Records, a music distribution platform that enables artists to publish their catalogs across major streaming services and collect royalties via a custom Visa card, sought to decouple its business logic from its internal interface to open the platform to third-party integrations.

As a full-stack engineer, I participated in the design of a new Laravel API built on AWS infrastructure (S3 for media storage, Amplify for and EKS for container orchestration), while integrating third-party APIs from streaming partners including Spotify, Apple Music, and Deezer. I also maintained thorough documentation of features and rules using Confluence and Swagger, reducing onboarding friction for future developers. The team delivered a tested and functional back end within three months.
