A dark promotional graphic for an App.js ’26 Watch Along event in Kiel. The left side features bold text announcing the React Native and Expo community watch-along, including event details, icons, and meetup information. The right side shows a cozy office-style watch party with developers sitting together, watching an App.js conference talk on a large screen. The design uses React blue, yellow highlights, and a modern tech meetup atmosphere.

A graph comparing development time over multiple React Native versions for projects using Expo versus those without. The red line (No Expo) shows a steadily increasing development time, while the green line (After migration to Expo) initially has a spike for migration effort but then grows at a slower rate. Labels indicate ‘The migration’ and ‘After migration to Expo,’ suggesting that migrating reduces long-term development effort. The y-axis represents ‘Development time’ and ‘Profit / Time for features,’ while the x-axis represents ‘Time / React Native versions.’

A screenshot of a view saying: Oliver Kwast: The React Native Maestro of Bluesky! 🎶 Navigating code like a GPS in a labyrinth of recursion, Oliver's posts are a masterclass in nerdy finesse. " A quirky blend of tech enthusiasm and endearing self-reflection, sprinkled with cryptic memes for flavor.

Image of a code snippet of the Bluesky app showing a component that uses let for the component definition. Later this variable gets the memoized value of itself before it is exported.
A popular meme showing a man sweating as he contemplates pressing one of two red buttons. The man has his hand over his mouth, looking stressed as he decides which button to press. The first button is labeled ‘React Native 0.76 / Expo 52,’ and the second button is labeled ‘End-of-Year Work.’ The meme humorously conveys the struggle between prioritizing a software upgrade and completing important work tasks before the end of the year.
