Hello

I'm Joyce Lee

I'm a Software Engineer based in London. This is my life in code.

This is my story

I'm a software engineer based in London, currently working at Post Op, where I design intuitive mobile apps to make healthcare accessible to everyone, everywhere. Outside of work, I dive into the fascinating world of AI, where I experiment with different machine learning models to explore the potential of data. When I'm not immersed in coding, I enjoy playing a game of chess, reading a good book, or hiking up a mountain where I question all my life decisions around the third mile.
