About me

A little about me.

I was born and brought up in Kottayam, Kerala, and I’m a B.Tech graduate in Computer Science. My journey as an engineer has moved from blockchain engineering and open source at Servntire and the Helix Network, through leading distributed teams at NetObjex, to engineering leadership at BitGo.

Outside of work, I enjoy coffee, travel, open source, and the occasional workshop room full of good questions.
