Message

At Globant, I worked with three financial-sector clients, including on a cross-platform virtual wallet serving 2.8M active users across five markets. I authored more than 80 components for a React and React Native design system, with 90% test coverage, and helped drive adoption across seven product teams.

I integrated more than 10 utility payment providers for web and native clients handling over 1M transactions per month, and hardened payment flows to cut production errors by about 50%. At TSO Mobile, I rewrote 10 core fleet-tracking modules from Angular to React, building live maps and operator dashboards.
