At @100xDevs, when you get a p0 task, you know you’re in for a ride—a chance to build something from scratch destined for the main repo, and I embraced the challenge head-on. Warning: TL;DR ahead—but worth it! #Thread aptitude-test-web.vercel.app… (Thread 1/8)

introducing @zerithstudio from ideas to execution. built for the internet generation.

We just released react-native-runtimes! 🥳 👉 Render React components on separate JS Runtimes 👉 Share state (Zustand) across Runtimes, synced in C 👉 Dual-Thread-approach for rendering/business logic We plugged this into MetaMask which made the app start substantially faster:

AI is a multiplier, not a replacement. If you don’t know what you’re building, the agent will happily give you garbage at high speed. And then we blame AI. But whose fault is that really?

Top three things to optimise list performance in React Native: 1. Use LegendList 2. Load thumbnails first, defer full-res images 3. Prefetch real images when needed

Software Engineering Expectations for 2026 - The majority of your code should be written by AI now - Cursor/Codex/Claude Code/Gemini/etc - You should try all the tooling and switch between them, as each one gets an edge over the others depending on the release cycle. - You should be using AI to check the code that is written by AI - Have AI write tests - Have AI read logs - Have AI navigate your browser - I don't do this every time because sometimes it's simple enough to check it myself - You should still skim code changes - This can be a lighter skim on internal tools and a heavier read through on customer facing code - Use AI to help you define specs

React Native 0.83 is now available! This release includes React 19.2, new React Native DevTools features, and support for new Web APIs. And, it's the first React Native release with no user facing breaking changes. reactnative.dev/blog/2025/12…

Unofficial holiday!

Using the blur trick for optical alignment

Half the fun of CS now is exploring the unknown. AI knows the 95%, the last 5% is where you feel accomplished/challenged

Don’t blame the game. Learn to play.

we are all just pattern-recognizers.

To your point, having AI-assisted tools to build apps (with React Native or anything else) is part of your experience IMO and interviews should account for that. At Expo I tell the team using AI is a skill and in 5 years we will be glad to have been practicing it day by day (or regretful and possibly feeling threatened if we do not). We are also embracing AI in interviews for this reason. However it can be useful to show or tell an interviewer about an actual RN app or native module you built. Having run into the “unknown unknowns” is valuable especially with how inconsistently (un)reliable LLMs are. It’s worth going through the motions at least once. On this tangent we are working on dependable AI, most recently with Expo MCP Server which feeds up-to-date docs to LLMs and lets agents interact with mobile simulators (tap, screenshot) and verify their work before interrupting the human. In the future I hope we can feed app state, the view hierarchy, and all types of errors to the agent.

Today we also want to celebrate React Native turning 10! What started as a small hackathon project is now used by millions of developers around the globe.

With 0.82 now the latest stable version of React Native, 0.79.x moves to unsupported. For more information on React Native release scheduling and support status, check our revamped releases page. reactnative.dev/releases
