In this episode of The CTO Podcast, Lucas and Luna dig into how Notion's engineering team reduced notification noise by 70 percent, a project that started with a simple question: why do users keep muting our alerts? They walk through the technical decisions, from consolidating event streams to building a relevance scoring model, and the surprising trade-offs that came with it. Along the way, they talk about measuring user engagement without falling into vanity metrics, and how a small team can drive a big infrastructure change without breaking the product. If you're building a system that sends notifications, or just curious about how real engineering teams tackle user experience problems, this one's for you.

They explore real-world strategies like rightsizing instances, leveraging read replicas, and adopting serverless options, using examples from companies like Airbnb and Shopify. The conversation covers how to approach cost optimization as a proactive practice rather than a fire drill, and why focusing on data lifecycle management can yield significant savings. Tune in for practical advice you can apply to your own infrastructure.

In this episode, Lucas and Luna dive into the engineering decisions behind Datadog's observability platform, which processes trillions of data points daily. They explore how the company evolved from simple dashboards to a full-stack monitoring powerhouse, the trade-offs in balancing real-time ingestion with long-term storage, and the recent shift toward AI-powered anomaly detection. Learn how Datadog accelerated its feature velocity by standardizing on a common data platform, and why that architectural bet paid off even as rivals like Grafana and New Relic intensify the competition. The hosts also discuss the cultural challenges of scaling an engineering org from a hundred to over five thousand people, and what other CTOs can learn from Datadog's approach to hiring and team topology. Plus, the episode touches on the broader trend of observability as a critical business function, not just a tool for debugging. A must-listen for technical leaders navigating the complexities of modern distributed systems.

In this episode of The CTO Podcast, Lucas and Luna dive into the engineering decisions behind Figma's dramatic reduction in prototype latency. They explore the shift from a synchronous request-response model to an event-driven architecture, the adoption of WebAssembly for client-side computation, and the importance of caching at every layer. Along the way, they discuss the trade-offs of moving logic to the edge, the challenges of maintaining consistency in a distributed system, and how Figma's team balanced performance with feature velocity. Tune in for a masterclass in latency reduction that any engineering leader can learn from.

In this episode, Lucas and Luna dive into the meteoric rise and sudden fall of disposable vapes. They trace how a single device went from a California startup's novelty to a global phenomenon, and then to a regulatory casualty. With the FDA's market denial orders and a looming 2026 federal ban, the hosts examine the economics of the industry: the razor-thin margins, the supply chain race, and the unintended consequences of regulation. They break down the numbers behind the boom—how a product that cost $2 to make sold for $12—and the bust, as inventory piles up and companies pivot or perish. The conversation also touches on the bizarre aftermarket for flavored vapes and what the crackdown means for the broader e-cigarette market. If you've ever wondered how a product can conquer the world and disappear in under a decade, this episode has the story.

In this episode of The CTO Podcast, Lucas and Luna dive into how Shopify cut build times from over an hour to under five minutes using Bazel, remote caching, and a carefully managed monorepo. They explore the engineering trade-offs, the cultural shift required, and the surprising win that came from treating developer tooling as a product. If you run an engineering org wrestling with slow builds, this is the roadmap you've been waiting for.

Lucas and Luna dig into how Duolingo slashed translation costs by 40 percent by building a custom machine-translation pipeline for its course content. They walk through the tradeoffs between generic MT engines and a tailored model, how the team balanced quality with speed, and what lessons any engineering org can take when considering build-versus-buy for AI. Along the way, they touch on the surprising role of human reviewers and the economics of running your own inference infrastructure. A concrete case study for anyone wrestling with AI costs and quality at scale.

Wikipedia is one of the largest websites on Earth, yet its engineering team is famously small and its codebase famously pragmatic. In this episode, Lucas and Luna dig into how Wikipedia keeps its technical debt low despite running on MediaWiki, a codebase older than most of its contributors. They explore the decisions that keep the platform maintainable: the strict policy on backward compatibility, the use of feature flags to manage risk, the practice of eating your own dog food by running beta features in production, and the culture of 'boring technology' that avoids shiny rewrites. They also look at how Wikipedia handles the tension between innovation and stability, and what any engineering leader can learn from a project that has been running continuously for over two decades without a major rewrite. If you're a CTO or a staff engineer wrestling with legacy systems, this episode offers a refreshing counterpoint to the constant pressure to modernize.
