Each episode of The CTO Podcast with Fexingo examines a specific engineering leadership challenge — from scaling a microservices architecture without creating a distributed monolith, to managing the cognitive load of a 200-engineer org, to choosing between a monorepo and polyrepo strategy based on team topology. The conversations are grounded in real-world cases: how Etsy restructured its data pipeline after a 2019 outage, why Stripe’s API versioning policy reduces breaking changes, or what Basecamp’s choice of SQLite over PostgreSQL says about product philosophy. Lucas brings the journalistic rigor — citing commit histories, RFCs, and postmortems — while Luna pushes back with the pragmatics of org dynamics, hiring constraints, and technical debt. There are no hot takes, no vendor pitches, no ‘best practices’ without trade-offs. Each episode ends with a specific tension left unresolved: the optimal number of direct reports for a VP of Engineering, the point at which a monolith should be broken apart, or whether a platform team should own the CI/CD pipeline.

In this episode, Lucas and Luna explore how Walmart rebuilt its supply chain on real-time data from edge to shelf. They break down the 2019 shift from batch processing to streaming events, the use of Kafka at massive scale, and how a machine learning model called 'Eddie' predicts demand by the hour. Lucas explains why Walmart moved its inventory management from mainframes to a cloud-native architecture built on Google Cloud, and how real-time visibility reduced out-of-stocks by 16% in pilot stores. The conversation covers the technical trade-offs—why they chose Apache Beam for processing, how they handle data locality across 4,700 stores, and what happens when a hurricane disrupts the supply graph. Luna pushes back on whether smaller retailers can replicate this, and Lucas outlines the core principles that transfer. This is a deep, non-obvious look at how the world's largest retailer treats logistics as a data platform. #Walmart #SupplyChain #RealTimeData #ApacheKafka #ApacheBeam #GoogleCloud #MachineLearning #InventoryManagement #DataEngineering #TechArchitecture #BusinessAndTechnology #CTO #Logistics #RetailTech #StreamingData #EdgeComputing #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Walmart's supply chain is the largest in the world, moving over 5 billion units annually.
