Valtech

Leading frontend development across multiple simultaneous client projects — including a React Native post-booking self-service app for Aerolíneas Argentinas, two Flutter apps for Berel (Mexican paint brand), a React Native superapp for Siman (Central American retail), and a React Native e-commerce app with a Fastify BFF for Unisuper/La Torre (Guatemala).

Driving technical health initiatives: incremental dead code cleanup, Redux modernization, and improved test coverage using react-doctor and Knip to measure and reduce unused exports.

Establishing architecture standards across teams: feature-based architecture, BFF patterns, XState for complex flows, and TanStack Query for server state management.
