EssJayKay.dev — experiments, software, engineering notes and selected work by Subhojit Karmakar. Solo full-stack developer and software engineer building web systems and interactive graphics.

I DON'T JUST BUILD INTERFACES.
I ENGINEER DIGITAL VELOCITY.
EVERY PIXEL IS A
CALCULATED MOVEMENT
IN USER EXPERIENCE.

I build software independently, with equal attention to how it works and how it feels. The work here spans products, experiments, and the technical decisions behind them.
