Overview

I've spent 15 years on iOS apps - first at Lazada, now at VNG. Built the experimentation framework 31 product teams use to ship changes safely. Wrote the Swift service that now handles 59 million requests a day. Before that: SoftBank and Atlassian. Most at home with Swift and Core Data. I read too many books about cities.
