I'm Mandar.

Engineer·Developer·Pentester

A computer engineer who writes code that works and scripts that fail working code. I build backend systems. I penetrate applications to fix loopholes and secure the internet.

I love science, math, technology, the ocean, space, time, and maybe everything that keeps me obsessed.
