10:35 Fleming (3rd Fl.) Session architecture From DVDs to Global Streaming: How Netflix’s Commerce Architecture Actually Evolved Kasia Trapszo Principal Engineer @Netflix, Leading Architecture for the Commerce Platform Netflix didn’t start as a global streaming platform. It began as a US-centric DVD-by-mail business, with a commerce system designed for one country, one currency, and relatively simple payment flows. As Netflix expanded internationally, those early assumptions began to break. 11:45 Fleming (3rd Fl.) Session AI/ML Behind Booking.com's AI Evolution: The Unpolished Story Jabez Eliezer Manuel Principal Engineer @Booking.com - Building Next-Gen AI Platform It’s easy to look at a mature AI platform and imagine a grand blueprint. Ours began with none. What started as a few data scientists hacking on Perl scripts and Mysql queries has grown into an AI platform that impacts millions of travel decisions every day. 13:35 Fleming (3rd Fl.) Session architecture Evolving Wise Architecture to Power a Global Account Andrei Tognolo Staff Engineer @Wise, 19+ Years in Software Engineering, Previously Senior Consultant @ThoughtWorks We all strive for loosely coupled and highly cohesive systems, yet as products scale, it is not uncommon for architecture to drift towards a “distributed big ball of mud” where a single change requires cascading changes across multiple services. 14:45 Whittle (3rd Fl.) Session architecture One-to-Many Products, One-to-Many Countries: Scaling Nubank to 127 Million Customers Laís Oliveira Principal Engineer and Platform Engineering Architecture @Nubank Cloud-native tooling and platform engineering promise everything we need to run software at scale: public clouds, infrastructure as code, developer tooling, and well-understood deployment and scaling models that abstract away complexity. 15:55 Rutherford (4th Fl.) Unconference Unconference: Architectures You've Always Wondered About 17:05 Whittle (3rd Fl.) Session Platform Engineering Modernising Retail at Scale: Architecting a Cloud‑to‑Edge Platform for a Global Enterprise Jayesh Bhayani Sr Director Technology @Tesco PLC, Board Member at Tesco Technology and Services Europe, Board Audit Committee Member of Tesco Mobile Modern retail depends on a technology platform that operates consistently across digital and physical channels - from customer experiences to colleague tools and the supply chain that supports them.
