Summary
👤
SeniorJens Lettkemann is a web designer and developer with 10 years’ experience crafting accessible, high-performing WordPress sites and design systems from Figma to production. He specializes in WCAG 2.2 accessibility, DSGVO-compliant consent UX, semantic HTML and Gutenberg block themes that teams enjoy maintaining. Jens blends UX research, information architecture and a component-driven approach to deliver measurable conversion gains and reliably green Core Web Vitals in real-world usage. He also runs e‑commerce and brand projects end-to-end, so he understands product, ops and legal compliance—not just pixels. His pragmatic focus on understandable forms, visible focus states and screenreader-tested flows reduces legal and usability risk while building trust. If a website should feel natural to every user and protect privacy by design, Jens pairs that ethic with hands-on implementation.
