**Main Talks**

**1.** **Using Hugging Face's smolagents framework to create a Fantasy Premier League AI Agent** - [Geir Freysson](https://www.linkedin.com/in/geirfreysson)

How do you ground AI agents in real-world data so they don’t hallucinate? This talk shows how I built a Fantasy Premier League agent using Hugging Face’s smolagents - a minimal, \~1,000-line framework. It connects directly to structured FPL data to give accurate, context-aware answers. Even if football isn’t your thing, it’s a practical talk of how to expose real data to LLMs and build useful agents without heavy infrastructure. The agent is at fpl.withrobots.ai and the source-code for the agent template so you can build your own is at https://github.com/geirfreysson/smolagents-template

**2\. No More Boilerplate: Data\-Driven Testing Made Easy \-** [Antonio Feregrino](https://www.linkedin.com/in/antonioferegrino)

Learn how to streamline that process using PyTest fixtures. We’ll look at a fixture-based approach to reading test data across multiple formats (JSON, CSV, YAML, JSONL, plain text), and how it can make your tests cleaner, more maintainable, and easier to scale. I’ll also introduce a decorator that lets you parametrise tests directly from data files, enabling true data-driven testing without the clutter.

**⚡ Lightning Talks**

2. USearch: The Engine Behind Most New Search & RAG Pipelines - [Ash Vardanian](https://www.linkedin.com/in/ashvardanian/)

**Logistics**
Doors open at **6.30 pm** (get there early as you'll need to sign in with building security). Talks start at **7:00 pm**, with drinks afterwards from **9:00 pm** at The Banker (EC4).

We have reduced capacity for this event, but there will be plenty of people to discuss data science questions with!

Please unRSVP in good time if you realise you can't make it. We're limited by building security on the number of attendees, so please free up your place for your fellow community members!

PyData Seattle Conference 2025

Online event

**Join us this Saturday, November 8, 2025, from 7:00 – 8:00 PM (PHT) for another DEP DataMasters talk:**
🖥️ Topic: Importance of Data Visualization
🎤 Speaker: Macky Sunga

**Can a simple scatterplot be powerful enough to prevent a tragedy?**

Join us as we listen to another great storytelling session on how data visualization is an **essential tool for communicating events/phenomena** that are observed from **collective data**.

Avoid the common pitfall of doing visualization just for the sake of doing it. We are reminded to be intentional with every chart that we create.

👨‍💻 About the Speaker:

**Macky Sunga** is a full-time Tech Hub Engineer with a solid 14 years of experience in IT. He's also a part-time faculty for DLSU and NBS College, while juggling his MS in Data Science at AIM.

From Idea to Acceptance: How to Craft a Standout Tech Talk Proposal

DEP AI Study Group: Building a Chat Agent Using Chainlit
🗓️ Date: November 14, 2025 (Friday)
🕕 Time: 6:00 – 7:30 PM
📍 Venue: Online via Discord
🎙️ Speaker: Johann Tagle, Infrastructure Architect at Packetworx

In this session, we’ll explore how to build an intelligent chat agent using Chainlit: a powerful framework for developing conversational AI applications. We’ll start from a simple chatbot and progressively enhance it with tooling, Retrieval-Augmented Generation (RAG), and guardrails for safety and control.
The demo will use the OpenAI API, but participants are encouraged to experiment with their own LLMs. The UV package manager will be used for environment setup, so please have it installed prior to the session.
