Senior Frontend Developer at IBT Health building HIS-FHIR clinical screens and a Storybook design system.

Argentina

Message

At IBT Health, I work on HIS-FHIR, a clinical records system based on HL7 FHIR. I develop frontend areas including scheduling, patient registration, admissions, and clinical screens.

I integrated a design system with tokens, primitives, and Storybook into the product. I also use Cursor to move GitHub issues through to pull requests and work with tests and FHIR contracts.

Previously, at BANCO GALICIA ARGENTINA, I developed features for business home banking across React Native and web, and built NestJS microservices. I’ve also worked on mobile and web products in health, tourism, e-commerce, and energy logistics.
