Jonatan Jansson
Summary
Senior full-stack developer and technical architect with a track record of owning projects end to end, from architecture through deployment. Deep expertise in WordPress ecosystems, modern static-site generators and CMS solutions, and AI-augmented development workflows. A natural problem solver who is equally comfortable shipping production code and enabling non-technical teams through clear documentation and hands-on training.
Full-stack across JavaScript/TypeScript, PHP, and Python with strong specialization in WordPress and Laravel, payment integrations, GDPR-compliant architectures, and CI/CD automation. Proven results in performance tuning, conversion tracking, tag management (GTM/GA4), structured data, growth engineering, AI tooling optimization, and delivering digital properties that move the needle on business outcomes. I like solving problems for a living, simply put.
