Email and front-end engineer with ~7 years across design and front-end, focused on building and automating lifecycle email systems. I code responsive, accessible email templates and in-app messages, and I like turning production workflows into fast, reliable pipelines. Most recently at Prezi, I replaced a manual production cycle with an AI pipeline (Claude writes, Cursor assembles, Braze ships), cutting campaign build time from hours to minutes. I’ve also shipped cross-client email experiences and run large-scale A/B tests, iterating winners back into the ongoing lifecycle.…Email and front-end engineer with ~7 years across design and front-end, focused on building and automating lifecycle email systems.
