# Maria Jose Reyes > UX/UI Developer & Engineer | Translate User Needs & Business Goals into Interfaces that Delight Users | Mobile & Web Applications | Human-Computer Interaction (HCI) | Publish to Apple App Store and Google Play Store Location: Cambridge, Massachusetts, United States Profile: https://flows.cv/mariajosereyes I’m an experienced User Experience / User Interface (UX/UI) Developer and Engineer with 6+ years of experience in React and React Native. I have proven ability to translate user needs and business goals into intuitive, engaging, and responsive user interfaces. My specialties include Human-Computer Interaction (HCI) and creating user-centered mobile and web applications with attention to accessibility, UI coding standards, and best practices. I publish apps to both the Apple App Store and Google Play Store. My fluency in English and Spanish have empowered me to gain hands-on localization experience in both languages. I collaborate with designers, backend developers, and scientists to integrate domain-specific requirements and deliver high-quality solutions that delight users and exceed expectations. In 2020, I was part of the team that earned a CES Innovation Award. I create wireframes, mockups, and interactive prototypes to visualize and test ideas. I’m experienced with tools like Figma, InDesign, Illustrator, Photoshop, Premiere Pro, and Axure RP. On the development side, I am experienced with JavaScript, TypeScript, and Java, and I build interfaces using React and React Native. I’m technologically agnostic, if there’s a tool or approach better suited to solving a problem than what I already know, I’ll learn it and use it. My background in both design and development helps me contribute across the entire product lifecycle, and I’m always looking to grow and adapt with the field.
