  • Why Your React App Renders 400ms Slower Than Necessary

    Lucas and Luna unpack a real-world performance bottleneck that silently plagues many React applications: unnecessary re-renders caused by unstable callback references. Using a concrete example from a mid-size e-commerce site, they walk through how useCallback and useMemo work under the hood, when they actually help, and when they make things worse. They also reveal one surprising React profiler reading that showed a 400-millisecond render delay from a single inline arrow function. If you write React code—or review it—this episode will change how you think about component memoization.

  • How One Serverless Function Cost a Startup 28 Hours

    Lucas and Luna kick off The Web Development Podcast by dissecting a single real-world failure: a serverless function that ran wild and racked up a $47,000 bill for a 12-person startup. They break down why 'it works on my machine' thinking is dangerous, how cold starts actually work under the hood, and what a proper error budget looks like. Along the way, they preview the show's style — specific numbers, real cases, and a refusal to hand-wave about 'best practices' without showing the trade-offs. No hot takes, no tool-worship. Just two developers talking through the decisions that actually matter when you're shipping to production.

About The Web Development Podcast with Fexingo: Frontend, Backend, and Modern Web Stack

From the publisher's feed

The Web Development Podcast with Fexingo is Lucas and Luna's weekly exploration of the modern web stack, from frontend frameworks to backend infrastructure. Each episode dissects a specific technology or workflow — think React Server Components vs. traditional SSR, the economics of cloud-native databases, or the practical trade-offs of a micro-frontend architecture — with real benchmarks and open-source case studies. Lucas, a former full-stack engineer turned journalist, asks the hard questions about developer productivity and deployment costs, while Luna, a senior architect in a high-traffic fintech org, brings battle-tested insight into scaling and maintainability. Their conversations avoid hype: no breathless takes on the latest framework until they've stress-tested it against production data. The listener is a working developer (mid-level to senior) who needs to make informed decisions about tooling, architecture, and team practices. Expect arguments backed by numbers — like Redis vs. Memcached under 100K QPS — and candid postmortems of real outages. You'll leave each episode with a sharper mental model of the web's moving parts, and maybe a new library to try. But Lucas and Luna won't sell you a silver bullet; they'll hand you a weighted decision tree.
