Wallapop Data Science Meetup

Come join us in this Meetup to discover how Data Science and Machine Learning are done at Wallapop and Veepee.

Wallapop’s Machine Learning Platform Journey: Martí will talk about the journey of building a Machine Learning Platform for Wallapop. Why it was needed, what we have learned, its evolution, and its future. How we use Sagemaker for model deployment, Flyte for ML pipelines, and DBT/Datahub for data lineage and quality.

Help Center Retrieval Augmented Chatbot: Iñaki will show us how to develop a RAG-based chatbot for a help center. In particular, we will explore prompt engineering best practices, fine-tuning, RAG and agents, and how to evaluate such a product. We will finish with a live demo of the chatbot.

Personalization on a Large E-commerce Site: Joel will explain how personalization works in a large-scale e-commerce site such as Veepee. We will present the work from end to end and introduce the different layers needed to successfully deploy and monitor our machine learning personalization algorithm.

After the talks, we'll enjoy some drinks and pizzas with you all.

Location: Wallapop Office, Avda Meridiana 89, 7th floor
