Jonatan Jansson
Full-Stack Developer, MarTech and Automation
I own the web platforms marketing and sales run on, and the integrations between them and the systems the revenue teams work in. At Nordhealth that meant 11 multi-market properties: I replaced a fragile manual release process with pipelines that deploy without downtime, and shipped AI agents built on Claude that generate CMS components together with the Playwright tests that check them. Publishing no longer waits on a developer.
I work with RevOps rather than for them. They point at a step still being done by hand in a Go To Market initiative and I automate it, with Zapier or a small service written for the job. I look after the measurement too: GA4, Tag Manager, HubSpot CRM, and A/B tests run against conversion.
At Block Labs I led a team of three on a real-time platform carrying thousands of concurrent sessions, and at IPTOR I had ownership across 20+ properties in the GENII group, including HubSpot integrations (SSO, CRM, CMS) and CMP audits of every domain in the portfolio. Before that, I delivered for 50+ clients in e-commerce, the public sector and enterprise at Duva.
I work as comfortably across JavaScript/TypeScript, PHP, Python, Bash and SQL as I do in the tooling around them. I write the documentation and run the sessions that let non-engineer teammates serve themselves. I take things end-to-end, and I'm as useful alone with the details as in a room with four other teams.
