Piotr Ceranek
Allegro

Engineering Manager at Allegro

I have been a developer for about ten years, five of which I’ve spent at Allegro. I started my journey working on an A/B testing platform before moving to the team responsible for maintaining the home page and developing automation tools for site content management.

During my time here, I’ve:

  • Participated in two major redesigns of the home page.
  • Managed traffic reaching 45,000 RPS (Requests Per Second).
  • Optimized content rendering services to handle that scale.

For the past three years, I have been the Manager of this team. My primary mission has been shifting the user's role from a creator or editor to an overseer of automatically generated content.

On a personal note, I’m a husband, a dad, and a total bike geek.

AI-First at Allegro Scale: How the Agentic Engine Revolutionized the Homepage?
Conference (INTERMEDIATE level)
Room 4B

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.
