About Pixels to Packages

Pixels to Packages dives into the invisible machinery behind modern life, uncovering what really happens between pixels on a screen and a package landing at your door. Through clear, down-to-earth conversations, we explore browsers, packets, Wi-Fi, the internet, data centers, and payments, then follow that trail into global supply chains with fulfillment centers, warehouses, robots, delivery trucks, and packages arriving at front doors. We break down how all of these systems actually connect, where the magic really comes from, and why understanding them matters more than ever. Pixels to Packages is hosted by Allan Leinwand, Chief Technology Officer (CTO) at Webflow and formerly CTO at Shopify, Senior Vice President of Engineering at Slack, CTO at ServiceNow, CTO of Infrastructure at Zynga, CTO at Digital Island and an early engineer at Cisco Systems. Allan has spent decades building and operating the real infrastructure behind the modern Internet, from large-scale networks and data centers to the software platforms that power commerce, collaboration, and the web itself. He has a deep love of technology and a rare ability to explain how it works, not as abstractions, but as concrete systems made of code, hardware, and physical constraints that shape everyday life. Having helped design, scale, and run the systems that connect pixels on a screen to real-world outcomes, Allan brings a uniquely practical perspective to Pixels to Packages, bridging the digital and physical worlds and showing why these hidden systems matter. Find Allan at linkedin.com/in/aleinwand and @leinwand.

Episode 6: The magic of routing

In this episode of Pixels to Packages, we explore one of the most important and least visible systems behind modern life: routing. From internet traffic moving across global networks to physical packages traveling through warehouses, trucks, aircraft, and delivery hubs, the same fundamental challenge appears again and again. How do you move enormous numbers of things through constantly changing systems when no single part of the network sees the entire picture? Along the way, we look at how the internet continuously adapts to failures, congestion, shifting demand, and changing conditions in real time, and why global logistics networks operate in surprisingly similar ways. Routing stops looking like just a networking concept and starts looking like one of the foundational coordination systems underneath modern infrastructure itself.

Episode 5: The complex pixels of commerce (with Shopify's Farhan Thawar)

In Episode 5, we move from pixels and intelligence into the moment money changes hands, following the full flow from landing on a storefront through everything that happens after you decide to buy. With my friend, Shopify’s Head of Engineering, Farhan Thawar, we trace the path from storefront to cart to checkout, unpacking how APIs, payments, fraud systems, and global infrastructure turn a simple tap into a confirmed order. From there, we step into the physical world of fulfillment, where inventory, warehouses, and logistics take over to move a package toward your door. Along the way, we connect it all back to AI and how these systems are starting to act on your behalf, pushing commerce toward a more automated future.

En fantastisk app med et enormt stort udvalg af spændende podcasts. Podimo formår virkelig at lave godt indhold, der takler de lidt mere svære emner. At der så også er lydbøger oveni til en billig pris, gør at det er blevet min favorit app.

Rigtig god tjeneste med gode eksklusive podcasts og derudover et kæmpe udvalg af podcasts og lydbøger. Kan varmt anbefales, om ikke andet så udelukkende pga Dårligdommerne, Klovn podcast, Hakkedrengene og Han duo 😁 👍
Podimo er blevet uundværlig! Til lange bilture, hverdagen, rengøringen og i det hele taget, når man trænger til lidt adspredelse.
