Hi! I’m a UX/Product tester and trilingual translator (English, Spanish & Portuguese) with over 6 years of experience in product validation and customer experience for global brands. In my current role, I validate infotainment systems, connected services and apps for major automotive brands, ensuring seamless user experience and quality across platforms. I’ve also built testing and feedback processes from scratch, so I know how to report bugs, usability issues and improvement ideas clearly and effectively. What I can do for you: • Test your mobile or web app, giving clear and structured feedback (usability, UX/UI, clarity, performance). • Translate or localise your content, product descriptions, or app text between English, Spanish, and Portuguese, keeping your brand tone consistent. • Review your website or marketing materials from a customer perspective. • Write concise and actionable reports with screenshots, steps to reproduce, and improvement suggestions. 🌍 Languages: • English (native level) • Spanish (native level) • Portuguese (native level) 🎯 Detail-oriented, fast learner, and passionate about helping products connect better with users. Let’s make your product easy to love — and your message easy to understand.
