In Episode 2, we pick up where the packets left off and zoom inside the browser to see how raw data turns into pixels. We break down HTML, CSS, and JavaScript, peek inside the JavaScript engine and its sandbox, and finally reveal the browser’s secret obsession with boxes. By the end, you will never look at a web page, or a buy button, the same way again.

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.&nbsp; 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.&nbsp; 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.&nbsp; 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.&nbsp; Find Allan at linkedin.com/in/aleinwand and @leinwand.
