I am a Computer Science undergraduate at the University of Cambridge, with a focus on full-stack development, AI applications, and software systems. My experience includes building responsive interfaces, secure authentication, serverless backends, and reliable integrations with large language models.
I also have a strong interest in visual design and human psychology, particularly how they influence the way people use software. I enjoy bringing engineering and design together to build applications that work well and are intuitive to use.
I use AI tools throughout development and am interested in how coding agents can support that work, as well as how to build reliable AI features into products.
