About Aldren Santos

Personal Website

Hi, I’m Aldren Santos and I’m a freelance graphic designer/illustrator for 3 years now. I’ve been assigned on making this site awesome as much as my skills can. I do hope my illustrations catch your attention on learning Python with these tutorials our team worked so hard for!

Also, you can check my artist shop for some merch that you might like.
