Hey, I’m Mary.

I’m a front-end engineer who loves turning complex, AI-powered products into clear, thoughtful experiences. I bring a strong design eye, an organized workflow, and a deep attention to detail to everything I build.

How I Work

Collaborative

I work closely with designers, product managers, and engineers to translate product goals into interfaces that feel intuitive and trustworthy. I believe the best products come from thoughtful collaboration and clear communication across teams.

Iterative

I prototype early, test often, and refine continuously. My goal is always to ship interfaces that are simple, accessible, and carefully crafted down to the smallest details.

Detail-oriented

I care deeply about the details—design systems, accessibility, performance, and clean code. Small improvements add up to products that feel polished and reliable.
