ArgentinaWhat I'm looking for
I’m a Senior Frontend Software Engineer with 9+ years of experience building high-quality web and mobile applications for Latam, U.S., Canadian, and European clients. I specialize in React.js, React Native (Expo), and TypeScript, and I’m deeply focused on component-driven architecture, state management, and cross-platform mobile development.
I consistently partner with product and design teams to translate wireframes and requirements into responsive, accessible, and performant user interfaces. I also lead cross-functional engineering efforts through technical discovery and strategic planning, and I mentor junior developers through structured 1:1s and code reviews to raise code quality and frontend best practices.
In my recent role, I served as Tech Lead for WeCollab, an end-to-end collaboration platform built with Ruby on Rails (backend) and React Native (mobile) serving 1k–5k users. I designed scalable, modular architecture, integrated BindX banking APIs for CVU creation and transfers (including real-time webhooks plus refunds/cancellations), and supported reliable deployments using AWS and CI/CD pipelines with tools like Docker, GitHub Actions, and Terraform.
