CURRICULUM VITAE

Marketing Engineer

summary

I build web platforms: the sites themselves, the pipelines that ship them, and the integrations that tie them to the rest of a company's tools. I've been doing it for over ten years, most often for marketing and sales teams, and the goal is always the same: the people who run a site should be able to change it themselves.

The work usually starts with someone pointing at a step that is still done by hand. I automate that step, with an off-the-shelf tool if that is enough or a small service if it isn't. Then I write the documentation and run the training, so the people who asked can keep it going without me. I look after the measurement as well, with analytics and A/B tests judged on conversion. Otherwise nobody knows whether any of it worked.

That has meant different things in different places. At Nordhealth it was eleven sites in several markets. I replaced a fragile manual release process with pipelines that deploy without downtime, and built agents with Claude that write CMS components along with the Playwright tests that check them. Publishing stopped waiting on a developer. At IPTOR I was responsible for more than twenty sites across the GENII group, including the single sign-on, CRM and CMS integrations and a consent audit of every domain. At Block Labs I led a team of three on a real-time platform with thousands of people on it at once. Before all that, at Duva, I worked directly with more than fifty clients in e-commerce, the public sector and large companies.

Around the building sits the less visible work: Core Web Vitals, accessibility, GDPR compliance, and integrations with whatever a company already runs. I write JavaScript and TypeScript, PHP, Python, Bash and SQL, and I'm as comfortable in what sits underneath them: Linux, Docker and CI. I'm happy alone with the details, and just as happy in a room with four other teams.
