Hello, I'm

Cristian Paul Castañeda.

Making things with websites and web-applications.

I'm a web developer specializing front-end development ( occasionally working with backend development ). Currently focusing in building accessible, client-server, JavaScript technology and its frameworks.


You can call me Paul, and I am passionate building things. I maintain, re-design, and can build from scratch. I started to keep up with web development in 2016. When I built a landing page website by searching what tools, environment, and asking communities what are the possibilities. I find it that people are actively looking for something around their phones browsers and making businesses online.

Fast forward to my current situation, I am now a freelance front-end web developer. Helping people and online businesses.

Actively working with:
