The Allegro homepage is our storefront, but beneath the surface lies a dynamic ecosystem hiding a massive configuration. Every day, our editors face configuration trees with hundreds or thousands of nodes and fill out templates containing thousands of lines of JSON. In this model, we reached a limit and needed AI to cross it. Over the past year, we have made a technological leap. Instead of forcing people to fill out dozens of forms, we implemented ACE (Agentic Engine). As a result, we transitioned from manual content creation to the role of a reviewer of automatically generated structures. In this presentation, I will explain how we did it, what obstacles we encountered, and what actually allowed us to achieve our goal.
