Demi Hayashi

Hi, I’m Demi, and I’m a full-stack developer based in Los Angeles who’s passionate about building thoughtful, user-friendly digital experiences.

My background is a mix of art and technology. I studied fine arts at the University of Florida, and somewhere along the way, I fell in love with code. Now I spend my time creating modern web applications that are accessible, performant, and actually enjoyable to use.

Over the years, I’ve worked with a wide range of technologies, from React and TypeScript to Node.js, SQL databases, and AWS. I’ve helped small businesses launch their first online presence, supported startups through fast-paced sprints, and currently contribute to a national publishing company where I’m leading front-end modernization efforts.

Whether it’s improving accessibility, refining UI interactions, or untangling legacy code, I care deeply about the little details that make a big impact. I love collaborating with teams that value clean design, clear communication, and meaningful work.

Outside of coding, I’m usually playing video games, learning a new language like Java and Russian, or watching true-crime documentaries with a cup of tea in hand.
