•OnlineDurable Agentic Workflows with Temporal.io
OnlineBuild a Multi-Agent Deep Research System with Temporal - Alexey Grigorev
In this hands-on workshop, you'll build a durable deep-research agent and learn how to make LLM-powered systems reliable enough for real production environments.
We’ll walk through:
- Building a deep-research agent step by step
- Handling failures and unpredictable LLM behavior
- Designing agentic workflows with Temporal + PydanticAI
By the end of the workshop, you'll know how to take an idea from PoC to a production-grade multi-agent system with Temporal: observable, fault-tolerant, easy to extend, and designed to survive real-life conditions.
About the speaker:
Alexey Grigorev is the Founder of DataTalks.Club and creator of the Zoomcamp series.
Alexey is a seasoned software and ML engineer with over 10 years in engineering and 6+ years in machine learning. He has deployed large-scale ML systems at companies like OLX Group and Simplaex, authored several technical books including Machine Learning Bookcamp, and is a Kaggle Master with a 1st place finish in the NIPS'17 Criteo Challenge.

•OnlineFoundations of Analytics Engineer Role: Skills, Scope, and Modern Practices
OnlineDuring this session, we’ll take a practical look at the Analytics Engineer role: what it actually covers, how it fits into modern data teams, and which skills matter most.
Rather than a step-by-step tutorial, this talk focuses on core concepts, real examples, and recurring patterns that define the work of Analytics Engineers today.
We’ll cover:
- What the Analytics Engineer role really includes and how it complements data engineers, data scientists, and business teams
- Technical foundations that keep an AE effective: SQL, data modeling, testing, version control, and development workflows
- Soft skills that quietly shape impact: cross-team communication, stakeholder alignment, and systematic thinking
The talk draws on key insights from Fundamentals of Analytics Engineering, with Juan sharing lessons learned while writing the book and working with data teams.
By the end, you’ll have a grounded view of why the Analytics Engineer role exists, how it has evolved, and which capabilities are worth prioritizing if you want to advance in this career.
About the speaker:
Juan Manuel Perafan is an analytics engineer, educator, and community builder based in Utrecht. He’s the co-author of Fundamentals of Analytics Engineering, host of the SQL Lingua Franca podcast, and a dbt Community Award winner. Juan founded the Analytics Engineering Meetup Netherlands and the Dutch dbt Meetup, and has spoken at events like dbt Coalesce, Linux Foundation OS Summit, and Big Data Expo NL.

•OnlineData Engineering Zoomcamp 2026 Course Launch
OnlineAlexey Grigorev, the course creator, will officially start the new cohort of the Data Engineering Zoomcamp in this live session. He’ll walk you through the course structure, key topics, and what you’ll build.
What You’ll Learn During the Session
Alexey will walk you through:
- What’s included in the course: topics, tools, and hands-on projects
- How assignments, feedback, and scoring work
- How to approach the material, even if you’re new to ML
- What it’s like to learn together with thousands of learners in the DataTalks.Club community
You’ll also have a chance to ask Alexey your questions live.
Thinking About AI Dev Tools Zoomcamp?
Data Engineering Zoomcamp is a free 9-week course covering infrastructure setup, workflow orchestration, data warehousing, analytics, batch processing, and streaming. The last three weeks focus on a capstone project in which you'll build an end-to-end data pipeline using a dataset of your choice, demonstrating data lake and warehouse solutions with documentation. Projects are peer-reviewed by fellow participants.
The new cohort of the Data Engineering Zoomcamp starts on January 12, 2026. You can join by registering here.

•OnlineFact-Checking with Wikidata
OnlineHands-On Methods Using MCP and Beyond GenAI - Philippe Saadé
In this hands-on workshop, we’ll explore practical solutions to fact-check with Wikidata. We will start by setting up the Wikidata MCP and giving an LLM the tools needed to explore Wikidata and test claims. Then we will move beyond GenAI and build a small experimental fact-checking system that uses semantic retrieval and a natural language interface classifier for a more controlled and interpretable approach.
We’ll cover the following steps:
- Introducing Wikidata
- Setting up the Wikidata MCP
- Fact-check with the MCP and GenAI
- Setting up a fact-checking solution beyond GenAI
- Retrieving Wikidata statements with semantic search
- Filtering statements with a reranker LLM model
- Classifying statements for fact-checking with an NLI model
By the end of this workshop, you’ll be able to understand how to use Wikidata for exploration and claim verification and build a small fact-checking pipeline in a controlled and transparent way.
About the speaker:
Philippe Saadé is the AI/ML project manager at Wikimedia Deutschland. His current work focuses on making Wikidata accessible to AI application with projects like the Wikidata vector database and the Wikidata Model Context Protocol.
