After building dozens of closed source websites (for customers) in the last 10 years, this is my very first public / open source project.
It's actually just my playground website to experiment with modern Front-End tech but I also try to offer interactive experiences like nature and cultures discovery. I'm using a design based on nature's philosophy and modern design.
I've designed it first in Figma. Figma is an awesome free (browser-based) design tool with plugin support and prototype functionalities. It works almost the same as Sketch but faster and for free.
After that I just started developing using html, scss, nodejs and jquery.
