Since December 2025 – Development of an internal SaaS for an energy brokerage and consulting firm: architecture design, deployment automation, and structuring of a business platform integrating AI and CRM synchronizations.

Creation of a platform from scratch in a context of high reliance on manual tools and time-consuming processes (invoices, CRM synchronization, data collection).

The challenge is to centralize, automate, and ensure the reliability of business processes while establishing a robust and scalable technical foundation.

The mission is long-term with evolutionary maintenance and continuous optimization.

Specifically:

Stack: Symfony, React, Vite, Docker, GitHub Actions, HubSpot, OCR, LLM, Web Scraping.

Impact: centralized business platform, advanced automation of invoice processing, reliable deployments, reduction of manual tasks, and improved data quality. Mission in progress.

January 2026 - Freelance PrestaShop Developer, on assignment for an e-commerce player in the music sector: technical upgrade, environment structuring, and application foundation stabilization.

Took over a PrestaShop site in a context of technical debt and lack of a development environment. The challenge was to secure a version upgrade, clean up the code, and prepare the project for future evolutions.

The intervention was intentionally short and focused.

Specifically:

Stack: PHP, PrestaShop, Docker.

Impact: sustainable development environment, cleaned-up codebase, secure version upgrade, corrected FR translations.
