01 — About
A little about my story.
I believe that technology can be used to change how we experience and navigate the world around us. My curiosity for what happens behind the user's experience led me to hours of research on how web applications come together, and how developers and designers are working towards more accessible applications.
My background is in psychology, and I care deeply about community and wellness. But it turns out I'm truly a problem-solver at heart. My love for web accessibility is accompanied by a drive for troubleshooting and debugging code.
Most recently, I completed the AI Engineering Fellowship at Resilient Coders in June 2026, deepening my ability to build AI-powered products responsibly and thoughtfully.
