Meet Julian — Practical GenAI for Data Engineering
Julian Wiffen, Chief of AI and Data Science at Matillion , has a simple reputation: he makes AI usable. Starting out in chemistry and early computational modeling, he learned to value experiments that actually lead to outcomes—not just interesting theory.
On The Executive Outlook, Julian shares how GenAI is changing data engineering in real terms: making unstructured data like text and documents usable, and speeding up ETL work through copilots like Maia. His examples show why reliability comes from constrained outputs and why context, schemas, and documentation are now the real foundation for AI success.
His approach is clear: build AI for daily work, define what “good” means early, and make it easy for teams to trust and adopt.
