Hey, I'm Andy Li

Senior Software Engineer from Hong Kong

As a passionate full-stack developer, I create amazing websites and web apps to make the internet a better place. I am an advocate for web performance and accessibility as well as a JAMstack enthusiast with experience in serverless technologies.

I am √1,024 years old and have been a web developer for as long as I can think. The technologies I work with are JavaScript, HTML and CSS with a focus on the frameworks React.js, Gatsby, Next.js, Node/Express, Python/Django, PHP/Laravel as well as data science. I use code not only to do my day-to-day job, but also to solve everyday problems I come across.

When I am not writing code I love to spend time with my friends at the gym doing sports like tennis. Every weekend we friends team meet & play the computer games relaxing stress piled up during the week's hard work. I myself speak 2 languages (English). Furthermore I enjoy cooking fresh food when I come home after a long day.
