We gathered again at Working & Co in Buenos Aires for another Ruby Argentina meetup. As always, the event was streamed live on RubySur’s YouTube channel, and our sponsors (SINAPTIA, Rootstrap, OmbuLabs, and Crunchloop) kept us fed and hydrated throughout the night.
Vacas, Rails y Blockchain
Ignacio Cesarani presented his thesis project: a cattle trading platform built with Ruby on Rails and blockchain. The interesting part is the architecture: it uses Ethereum RSK as a sidechain to record transactions immutably, while keeping operational data in a traditional database.
Break
After the first talk, we had time to eat, drink, and chat. The sponsors put together a good spread, and the atmosphere was the classic meetup vibe: people sharing what they’re building, making connections, and discussing both old and new problems.
De Heroku a Kamal
Fernando Silva Jacquier showed how he migrated a multi-tenant Rails app from Heroku to a VPS (Virtual Private Server) with Kamal. The most interesting part of the talk wasn’t the migration itself, but how he did it. Fernando shared that he worked with a Claude Code to perform the migration. And he didn’t show only the happy path: he shared all the problems he encountered, the failed attempts, the fixes, and the real experience of migrating infrastructure with AI assistance.
This meetup was possible thanks to the organizers, the sponsors (SINAPTIA, Rootstrap, Ombulabs, and Crunchloop), and everyone who showed up. We’re already looking forward to June’s online meetup.
