Senior Developer / Technical Lead · Frontend and mobile
I'm Nelson Aranda. I work with React, React Native, and Flutter, combining engineering, architecture, and technical leadership to make products and team workflows clearer.
Two examples of how I approach mobile architecture, integration, and technical collaboration.
A mobility product covering rides, access, and onboarding.
I established a mobile foundation to support growth and built reusable components and the technical side of a design system.
We prioritized a structure that could accommodate new features and support shared quality and delivery practices.
Two microapps integrated into the ueno bank app.
I led the technical integration of both and supported the development teams.
We worked within an existing Flutter foundation, following its conventions to add new modules consistently.
