About Me
In the Beginning was UX
Thank you to my parents for being good teachers all my life.
And they helped me take the first steps toward my dream back
in school. So, I found my way into design. It was a long journey through several experiences along the way.
Design Thinking and User-Centered Design are at the core of my approach. These methodologies help us frame the challenge, empathize with users, and prioritize their needs and pain points. Rapid prototyping is a crucial component, and I use tools like Figma to create interactive prototypes that simulate user interactions and flows. And Figjam to facilitate collaborative ideation sessions.
This approach fosters creativity, problem-solving, and a deep understanding of user needs, which are crucial in the fast-paced environment of Design Sprints. Go to Presentation Design Sprint
Besides work
During my off-project hours, you'll often spot me sweating at the gym or exploring different corners of the world. My heart sways between the beats of music and the tranquility of solitude, so you'll typically find me navigating a path somewhere in between these contrasting worlds.
My spectrum of interests spans various domains such as relationships, wellness, education, psychology, finance, entrepreneurship, blockchain,
and the ever-evolving landscape of technology.

Like anyone else, I cherish moments with my family, finding solace in books, reveling in celebrations, and embarking on global adventures. My devotion is reserved for a select few individuals and passions, considering everything else transient and fleeting.
