Hi! 👋
I'm Horacio Herrera, a product-minded frontend engineer and designer from Panama 🇵🇦, based in Barcelona. More about my journey →
I build rich-text editors, local-first apps, and collaborative publishing tools. I'm currently building Seed Hypermedia, a desktop and web platform for decentralized knowledge collaboration — combining fine-grained linking, embedding, cryptographic authorship, and community-controlled publishing.
My work sits at the intersection of product design, frontend architecture, and open-source software. I've contributed to editor ecosystems like Plate and BlockNote, and I care deeply about tools that help people write, publish, discuss, and organize knowledge.
You can find me in X, Bluesky, Youtube or email
