Product Design

I've honed my skills in designing user-centric products that boost business performance. With experience in user research, usability testing, and design implementation, I've successfully led projects from initial concept to continuous improvement. I've also collaborated effectively with cross-functional teams across various departments.

UX Design

I create low-fidelity wireframes and high-fidelity prototypes to visualize and iterate on design concepts, design intuitive interactions for user tasks and goals, and analyze user test data to identify optimization opportunities while ensuring everything is accessible and legible, which sometimes requires making the logo bigger ;)

UI Design

I design the UI's visual elements, such as colors, typography, icons, and imagery, to create a pleasing aesthetic while also incorporating motion and animation to improve usability. I use After Effects and Lottie to add microinteractions to the UI. In addition, I ensure that the UI adapts and functions properly across a variety of devices and screen sizes, working closely with the development team to ensure easy implementation.

Brand Strategy

I research the target audience, market trends, and competitors while working with stakeholders to define the brand's identity, which includes values, personality, voice, and visual elements. I also create guidelines for brand consistency across digital interfaces and marketing materials. I have experience developing new brands as well as rebranding both small and large businesses.

User Research

I conduct user research activities such as interviews, field studies, surveys, and usability testing. I also facilitate workshops and encourage cross-functional team collaboration. I analyze the collected data to identify patterns, trends, and insights that inform my design decisions.

Design System

I analyze design assets to establish fundamental principles for the design system. Utilizing tokens and variables in Figma, I develop reusable components. I collaborate closely with other designers and developers to ensure alignment between design system goals and implementation.

My design thinking

Designer generalist with an artistic background

Scalable design

I always design products with scalability in mind, ensuring they can evolve within a dynamic ecosystem.

My process

I customize my design process according to the unique needs of each project. I analyze data, engage users, identify obstacles, and map out a plan that leverages our strengths. Then, I deliver solutions that delight users and drive business growth. I always design products with scalability in mind, ensuring they can evolve within a dynamic ecosystem.

"Gut feelings"

I value designer intuition's power, which is often overlooked. While data-driven decisions are key, intuition lets us spot complex problems early. Embracing this gut feeling sparks productive discussions and leads to confident, well-rounded designs, especially when data is limited.
