I am currently working at Trifacta.

I was previously a Node.js software engineer at Zendesk. I wrote their real-time notification infrastructure (Radar) and many other things.

Before that I was a doctoral student (Information Systems Science) at Aalto University School of Economics. I have a Masters in Cognitive Science from Helsinki University, and am proud to be a United World College graduate.
