Assigned as a full-stack developer on Lodger, a B2B SaaS platform for real estate agencies, my main mission was to design and develop the agency dashboard from scratch, while actively contributing to the backend API (NestJS, GraphQL, PostgreSQL).

I designed and implemented a document processing pipeline based on BullMQ, enabling automated analysis and data extraction from business files. Each submitted document goes through a queue of asynchronous jobs orchestrating several stages: OCR, semantic analysis via local models, and structuring of extracted data. This architecture allows agencies to significantly reduce manual data entry when onboarding new properties or tenants.

The dashboard covers the entire agency lifecycle on the platform: property management, listing and publishing real estate and advertising ads, applicant tracking, integrated messaging, subscription management, and an advanced filtering system. For each feature, I handled both the React interfaces and the GraphQL endpoints on the API side.

Joined Korper, a FitnessTech startup based at Station F, as an apprentice during a complete platform redesign towards v2. My role covered the entire technical chain: migrating the existing architecture, developing new business features, and contributing to the company website.

I participated in the complete backend architecture redesign: migrating from MongoDB to PostgreSQL with redefinition of data schemas, adopting Fastify as the server framework, and developing a REST API with over 100 endpoints serving all company products (coaching web app, mobile app, back-office, website). I also implemented CI/CD to ensure reliable deployments.

I designed and developed a personalized recommendation algorithm to suggest workout programs tailored to each user's profile and goals.

I contributed to the development of Korper's landing page, handling the end-to-end user onboarding process, including Stripe subscription, which resulted in about thirty new subscriptions per month.

As an intern at C-Clerc, a LegalTech platform for notaries, I contributed to the development and improvement of their full-stack application (React, NestJS, GraphQL, PostgreSQL) by working on all layers: frontend, backend, and database.

The main feature of my internship was the design and implementation of a GDPR-compliant unsubscription system, covering over 100,000 end customers. This involved cross-cutting developments across the entire stack, from the user interface to database processing.

In parallel, I handled evolving and corrective maintenance tasks across the application: adding features, refactoring, and bug fixing in various parts of the product.
