Main Talks

1. Agentic Workflows for Data Engineers: How AI Agents Are Changing Our Daily Work - Yusuf Ganiyu
   Last month, I debugged a critical pipeline failure in 4 minutes that used to take 30. The difference? An AI agent that understands my data infrastructure.
   This isn't about replacing data engineers, it's about eliminating the toil that keeps us from high-value work. In this talk, I'll share practical experiments with agentic workflows from my work at AstraZeneca and teaching 20,000+ students at DataMasteryLab.
   We'll explore:

• What agentic workflows actually are (beyond the hype)
• Live demo: AI-assisted pipeline debugging with LangGraph
• Practical patterns: Schema evolution, data quality monitoring, self-healing pipelines
• The feature engineering bridge: Helping data scientists love you
• What AI still can't do (and why that matters)

Whether you're skeptical about AI hype or already experimenting, you'll leave with concrete patterns you can implement in your pipelines next week.
2. Explore the Kingdom - Cursor the Data Engineer - Jethro Reeve
I built explorethekingdom.co.uk over Christmas using Cursor with Opus-4.5 and GPT-5.2 for the data engineering and UI.
I've pulled ~15 Government data sources and have them represented on a map of the UK. This kind of data aggregation tool sells for thousands to niche consultancies. I built it while playing Minecraft on Boxing Day.
What would you use it for? (Why) Is the software world so slow to catch up with the capabilities of vibe coding?

Lightning Talks

1. Github Codespaces for Data Analysis with Python - Stelios Christodoulou
2. TBC
   --------------------------------
   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.
If you want me to trim lightning talks down to two or shorten any abstracts, say which ones.
