I am currently working as a software engineer at Zendesk, working on our pubsub/presence/status API and infrastructure and related front-facing features. It's kind of like what Pusher does, but different.

I was previously a doctoral student (Information Systems Science) at Aalto University School of Economics. I have a MA in Cognitive Science from Helsinki University, and am a United World College graduate.
