Prometeo: Building Banking APIs at Scale
I joined the podcast Cuando el río suena from Acueducto to talk about Prometeo, the experience of building API infrastructure at scale, and why usability always wins over technical purity.
Takeaways
- Perfect bank connections do not help if the product is painful to use.
- You have to watch logs and user behavior constantly to find the real drop-off points.
- Rebuilding and measuring repeatedly is often the only way to get adoption.
- Production bugs still happen. The job is to resolve them quickly and quietly.
- AI helps most when you already know what you are trying to build.
- Security and usability are tied together. A system that is hard to use usually suffers in adoption.
The conversation also covered operating critical infrastructure where failures affect real money, the challenge of keeping payments reliable, and the reality that technical perfection does not matter if the user flow fails.
