open to summer 2027 internships
Arjun Nair
full-stack developer
Second-year computer science student at CUSAT, Kochi. I ship small products, break them at hackathons and write about what I learn.
01 / about
I like building things people use
I started with a Telegram bot that told my hostel when the mess menu changed. Two hundred people joined in a week, and I have been hooked on shipping ever since.
These days I work mostly in TypeScript, Go and Postgres. I care about fast pages, boring infrastructure and writing the README before the code.
