Johan Terpstra

MarTech and eCommerce engineer, serial builder. By day it's email ops, SEO, analytics, WebPerf and customer data. By night I'm building Punditor, a live football room where you watch the match with both sets of fans, pick a side, and react as it happens. No algorithm, no pile-ons, just the crowd. Dutch, Heerenveen season ticket holder. Here to build in public and trade sharp, specific feedback.
