I specialize in crafting intuitive, playful web interfaces and love building products that blend functionality with delightful user experiences.

Whether it’s boosting accessibility, scaling design systems, or mentoring teams, I bring thoughtful engineering and creative problem-solving to every project.

</AboutMe>

Hi! I'm Stafny — my love for computers started way back in 5th grade when I thought opening Paint was pure magic. By age 10, I designed my very first website and never looked back.

What began as childhood curiosity turned into a passion for designing fun, functional, and beautiful things for the web. I quickly realized the browser was my favorite canvas.

These days, I spend my time building creative and accessible web experiences. I love bringing ideas to life with clean code, playful interactions, and a touch of digital flair.
