About me
Discover what I do
Full-stack developer with experience across multiple technologies and a love for free software.
Hi! My name is Andrés Puello and I greet you from beautiful Cartagena, the city where I was born and raised. My adventure with technology started as a kid with an old Windows XP PC; today I'm a Linux enthusiast (proud NixOS user — formerly Arch!) and passionate about development and design. I love learning something new every day, building plugins and helping the community solve code or design problems. If you're looking for someone who puts heart and craft into your web project or graphic design, you're in the right place! How can I help you today?
