The best thing about Sundays is that Opus 4.6 (max) is as fast as Haiku on a Monday morning.

[Pablo Postigo @iamposti]

Do you use Studio as part of your dev workflow? I want to talk with you, we are working on something exciting :)

🚀 Relentless shipping util finding a home stops being a nightmare.

Solo hay algo más caro que tu hipoteca: tu tiempo.

¿De qué sirve un piso barato si pierdes 2h al día en el metro?

🚀 Hoy Lanzamos "Travel Time".

Busca por tiempo de trayecto, no por barrios:
🚶‍♂️ 5' andando a la playa
🚴 15' en bici al trabajo
🚇 20' en metro al centro

I rewrote a full React + GraphQL SPA into Phoenix LiveView in just 2 days.

We originally chose React purely for the DX. LiveView has non-obvious conventions, but with AI handling the boilerplate, we get all the performance benefits with none of the headaches.

[Javier Cuevas @javier_dev]

One of the cool things about AI-assisted coding is that you can start choosing your tech stack based on actual performance, even if it means sacrificing some DX.

Two examples I've experienced lately:

[Javier Cuevas @javier_dev]

React Native is seeing an explosion of libraries tapping into native code for superior UX, like the new `react-native-ease` or the WIP `vercel/aix`.

Finally got to build this. Create animations that use Core Animation on iOS and Animator on Android with zero JS overhead.

Same animation. But one keeps running smoothly even when the UI thread is lagging.

Introducing react-native-ease 🍃

I haven't had this much fun building things since I was 11 and learned Microsoft FrontPage.

The "Severance" workflow

[Jamon @jamonholmgren]

My current agentic workflow is about 5x faster, better quality, I understand the system better, and I’m having fun again.

My previous workflows have left me exhausted, overwhelmed, and feeling out of touch with the systems I was building. They also degraded quality too much.

This is way better.

I’m not ready to describe in detail. It’s still evolving a bit. But I’ll give you a high level here.

I call this the Night Shift workflow.

was playing around with claudecode, ended up building a new portfolio (●´ω｀●) hope you like it !!

Google Imágenes 🤝 Buscar casa

Hemos enseñado a Keli a "ver y entender" las fotos de todas las casas de Madrid 📸

Literalmente, todas.

Prueba con lo siguiente:
🛋️ "Salón estilo nórdico con luz natural"
⛰ "Balcón con vistas a la montaña"
🌴 "Cocina americana con isla"

[Javier Cuevas @javier_dev]

TBH the best thing about this AI coding thing is that we can finally center divs.

[Javier Cuevas @javier_dev]

@walterk My current subscription is the top tier for @GitHubCopilot and I do run out of credits often (40% consumed this month so far 🥶).

I'd switch the Claude Code but I like being able to jump from one model to another (Opus, Gemini 3 Pro, GPT Codex ). I find all of them them useful!

Let's ship while it lasts.

Meanwhile, your average 100+ employee company is still debating whether to allow employees to use AI assistants due to IP concerns.

[Javier Cuevas @javier_dev]

Yesterday I wrote +18,000 LoC for a fully featured new React Native app. In a single Sunday.

The estimate in the original plan (drafted with an LLM) was 7 weeks.

There is no going back 🫨

[Javier Cuevas @javier_dev]

Ah, I also did the back-end in parallel 💅

(feels weird to use "I" here, should I say "we?")

[Javier Cuevas @javier_dev]

@MarkVillacampa monday creo que tiene gym en algunas locations

[Javier Cuevas @javier_dev]

@iamposti @Mr_Abraham_ AH, y los platos de acero inox

[Javier Cuevas @javier_dev]

@iamposti @Mr_Abraham_ En Madrid ya no te dan licencia de apertura si tu local no está pintado en tonos terracota 😅
