Quick life update: I’ve joined @Vercel Labs as a Software Engineer. I’ll be working on agent tooling with @ctatedev: agent-browser, json-render, portless, and more. Open source changed my career. Moved from Lima to Buenos Aires for this one. Let’s ship ▲

npm types can lie scriptc can now check values crossing from npm packages into your typed code against their TypeScript declarations → Mismatches throw a runtime TypeError → No validation code added to your app

> Don't wait for your agents. Let them wait on you. If you worry about TTFT, you're probably doing something wrong. Lean into async. Give them bigger tasks, be more ambitous. Yes
Finally summarized what I've been sending to friends in DMs

This is absolutely stunning! A static physics textbook turned into an immersive, interactive 3D learning experience. You can actually explore the concepts instead of just reading about them. Imagine if more textbooks were built like this.

I used to design my furniture in Sketchup, but these days it's faster, easier, and more fun to just spin up a custom jig for it. (Theme designed @withgraphical of course)!

Joined @vercel labs time to ship cool things lessgooo
Introducing Vercel Labs Tools for devs in the AI era agent-browser, skills, json-render, deepsec, fx, just-bash, portless, vgpu and more We experiment in public: ship early, learn from feedback, and keep working on what people find useful We've been shipping under the Labs name for a while. Now, Labs is an official team at Vercel focused on exploring new capabilities and primitives that change what developers and agents can do. Here's what to expect: → Labs products: maintained, supported, built to be relied on → Active experiments: moves fast, expect rough edges and breaking changes → Past experiments: ideas that become new projects, make it into existing products, or teach us what to build next vercel.com/labs?experiment-i…

I joined @neondatabase 💚 I'll be doing DX and leading open source at Neon. Also I guess I'm their mascot now. 😂 Orcs are green. Neon is green. It was meant to be. 🟢 I love Neon, and I love the team even more. This move just made sense. The channel stays OrcDev. Same orc. Same Horde. Follow along. Things are about to get interesting 👀
It's official. My new chapter. 🟢⚔️

My workflow keeps evolving: local agents → cloud agents → cloud agents + cloud subagents Latest is a graph: - each gets own sandbox - creds stay outside sandboxes - agents can message each other - github writes go through approvals - interactive sessions survive disconnect
