Hello, I'm Darrien!

I build applications and poke at new technology to solve real problems, mostly turning messy data into something people can actually use.

• About Me

I am a Computer Science and Statistics ex student at BINUS University, currently focused on Next.js and Artificial Intelligence. I work as a Product Specialist and founded Neurasphere, where I build the things I kept wishing existed.
