From SaaS to Open Source: Behind the Scenes of Toulouse Airport's E-Commerce Replatforming — Loïc Caillieux

We’re excited to welcome Loïc Caillieux, who takes us behind the curtain of one of the most business-critical journeys in airport commerce: what really happens when travelers book their parking—and what happens when the flow breaks.

In this talk, Loïc walks through Toulouse Airport’s 10-month migration from a restrictive SaaS setup to a flexible, future-proof Sylius-based architecture. You’ll hear why the team chose open source, how it unlocked business agility, and what it took to rebuild a core revenue channel without disrupting daily operations.

From smoothing out the buyer journey to integrating custom business logic, handling payments, scaling on demand, and applying fail-and-retry strategies, Loïc shares the technical realities and organizational decisions behind the project - plus what they’d do differently next time.

If you’re working with high-traffic transactional flows, fighting platform limitations, or planning your own replatforming, this session shows how Sylius helped Toulouse Airport regain control over their e-commerce engine.
