ABOUT ME

Builder. Shipper.

Profile photo

I build products end-to-end. I have shipped platforms used by thousands at Nation Media Group, led a full digital transformation for a multi-branch business from brief to deployment, and I am currently in Tallinn working on peer-to-peer learning infrastructure at Kood/Jõhvi. I work across product, engineering, and design — because good products require all three.
