About me
I explore Design as a dialogue between logic and humanity, with a clear understanding of what is truly possible to build. For 15 years, I have worked across projects in sectors such as finance, real estate, healthcare, insurance, and automotive, contributing to digital experiences that aim to create clarity, connection, and value, while strengthening my sense of responsibility behind every design decision. My Career, grounded in Design:
As a graphic designer, I learned to observe hierarchy, contrast, and organization. I developed a strong awareness of the relationship between form, function, and context, and came to understand that every visual choice communicates something.
As I moved into digital, I began designing interfaces for web and mobile products (iOS and Android). I deepened my knowledge of information architecture, interaction patterns, and accessibility best practices.
My specialization in HCI — Human-Computer Interaction — led me to design interfaces with a focus on human behavior, interaction patterns, and how people perceive and use digital systems across different contexts.
As I transitioned into User Experience, my focus shifted toward people. HCI helped me turn opinions and personal accounts into evidence to inform decisions. I learned to approach these narratives with curiosity, attentive listening, and an open mind.
More recently, I began exploring conversation design and the application of artificial intelligence in digital products, investigating how conversational systems can inform, guide, and interact with people in more natural ways.
This journey led me to the topic that now guides my Master's research: Design Ethics in the context of AI. My interest shifted beyond understanding whether a product works to investigating what it produces in the world.
Expertise
Research & Strategy
I use research to support decision-making, not simply to produce reports. I translate behaviors, needs, and contexts into insights that help products and businesses make more informed and conscious decisions.
Human-Computer Interaction (HCI)
My background in HCI helps me connect research to engaging and functional interaction solutions, while organizing information and experiences to improve findability, discoverability and Usability and overall user experience.
AI Experience (AIX)
My background in Human-Computer Interaction (HCI) connects with AI Experience (AIX) to create more natural, contextual, and trustworthy conversational interactions between people and systems. I design dialogues, behaviors, and personalities for AI agents, delivering the right information to the right person, in the right way, at the right time.
Ethical Design
I investigate the relationships between Design and Ethical Principles, exploring ethical approaches to understand how product decisions can create impacts that extend beyond the interface. My focus is on making these impacts more visible and incorporating responsibility, transparency, and ethical reflection into the design process.
