As a multidisciplinary professional in tech, I work at the intersection of user needs, ethical technology, product development, customer success, and QA, translating complex insights into clear, actionable outcomes that improve digital experiences, customer satisfaction, and strategic decision-making. I also bring 7 years of experience in customer service, where I developed strong skills in communication, problem-solving, and handling user needs with empathy and clarity. This experience allows me to effectively support users, manage expectations, and resolve issues while maintaining a positive and professional experience. Alongside this, I have experience in QA and product testing, where I review platforms to identify bugs, inconsistencies, and usability issues. I’m comfortable reproducing issues, documenting them clearly, and collaborating with teams to improve both functionality and overall user experience. Over the past ten years, I’ve focused on creating impactful digital experiences through UX research, UX design, and UX strategy, and in the past year, I’ve expanded into product management. Working closely with cross-functional teams, I’ve supported delivery planning, stakeholder alignment, roadmap definition, and customer-centered execution, strengthening the connection between user insights, business goals, and long-term customer success. I recently completed a Master’s in Design for Responsible AI at Elisava in Barcelona, where I focused on data governance, ethical frameworks, and building technology with a strong social and environmental lens. I’m committed to shaping digital experiences that are not only human-centered and inclusive but also responsible and climate-conscious. ⸻ Skills: UX Research · Qualitative & Quantitative Methods · Usability Testing · User Interviews · Survey Design · Data Analysis & Synthesis · Agile Collaboration · Cross-Functional Teamwork · Product & Project Delivery · Roadmapping Support · Backlog Management · User Stories & Requirements · Human-Centered Design · Customer Experience (CX) · Customer Support & Success · QA Testing & Bug Reporting · User Journey Mapping · Process Improvement · Stakeholder Communication · Problem Solving · Ethical AI · Data Governance Awareness Languages: English and Spanish (bilingual) · Learning Portuguese Interests: • Responsible tech and AI ethics • Cross-functional product delivery • Climate-positive innovation • User-centered digital experiences
