Tamizh SK Portfolio

Hi, I'm Tamizh 👋

Artist turned into a Developer. I love building things and helping people. Very active on LinkedIn.

About

Started as a graphic designer, freelancing and creating for the community. Along the way, I became a TEDx Speaker, blending creativity, storytelling, and a good dose of humor. Now, as an undergrad student, I’m all about exploring new tech, staying curious, and pushing limits - because giving up isn’t my thing!
