Senior full-stack engineer building scalable, modern web apps with microfrontends and AI-augmented workflows.
ArgentinaWhat I'm looking for
I’m a Senior Full-Stack Engineer with 8+ years of experience building scalable web applications, with a strong focus on frontend development in enterprise banking environments. I’ve consistently owned end-to-end delivery, from architecture decisions to production outcomes.
At BBVA, I led a zero-downtime migration from AngularJS to React and TypeScript across core banking modules, improving long-term maintainability. I also designed a scalable Microfrontend ecosystem using Lit-element and Cells to enable independent deployment and team autonomy.
On the backend, I design RESTful microservices and BFF layers with Node.js and NestJS, and I lead integrations with internal and third-party banking systems to keep data consistent and highly available. I augment my development workflows with LangChain and Pinecone, while maintaining reliability through CI/CD with Jenkins and Docker plus automated testing using Jest, Karma, and Cucumber.
