What I'm looking for

I'm looking to lead and build high-quality frontend products, especially applications involving payments, billing, analytics, and meaningful customer experiences.

At Tsoft, I lead frontend developers and build the core TUENTI application for bill management and checkout payments using React and TypeScript.

I've also integrated Google Tag Manager and Google Analytics, and previously delivered frontend features and store-partner integrations for Rappi and Mercado Libre clients at Avalith.
