How This Works

This portfolio demonstrates Hotwire Turbo with TYPO3, providing a fast, SPA-like experience without JavaScript frameworks.

Turbo Frames: Filter buttons update only the grid area via <turbo-frame id="portfolio-grid">. The rest of the page stays intact - no full page reload.
Turbo Drive: Clicking a project navigates via data-turbo-frame="main-content", replacing only the main content while the sidebar remains static.
View Transitions API: Modern browsers show smooth crossfade animations between page states using native CSS View Transitions.
Session Persistence: Your active filter is stored in the PHP session, so it's remembered when you navigate back from a project detail page.
Server-Side Rendering: All content is rendered by TYPO3 on the server. Turbo fetches HTML fragments - no JSON APIs or client-side templating required.

TL;DR:

creative frontend — animation, scroll, interactive maps, data-viz, demanding designs
full-stack on TYPO3, senior frontend on any backend (Nuxt, Rails, Craft, Node…)
25 years in web dev, still shipping modern code
high-traffic sites running smooth in production (700k+ monthly users)
journalist turned coder — fluent in both code and human
got a pilot's license because it's difficult
