About Me

Hey, I’m Sam Joe Chalissery, a 20-year-old developer who writes code like it’s second nature. I started off building Discord bots during lockdown, and these days I’m deep into full-stack development, automation, and exploring the world of Web3 and blockchain. I’m currently studying Computer Science, but most of what I know comes from diving into real projects and learning by building. I love taking bold ideas and turning them into software that actually solves problems. Got something cool in mind? Let’s build it.
