Teaching experience
"Students don't struggle because blockchain is hard.
They struggle because it's explained badly."
Parvathiney
Founder & Blockchain Educator — ISA
I started learning blockchain during my college days and noticed how confusing it felt for beginners. What began as helping friends slowly grew into college workshops, beginner sessions, and live classes.
Today, I focus on helping students and non-tech learners understand blockchain clearly and confidently, in English and Tamil, without jargon or hype.
