Building the web
with precision
and intent.

I'm Lucas Oberstaller — a frontend developer from Retz, Austria with a sharp eye for detail and a deep respect for the craft of building digital interfaces. I work at the intersection of design and engineering, translating complex ideas into fast, accessible, and visually strong web experiences.

My work ranges from editorial websites and brand platforms to interactive tools and progressive web apps. I believe in using the right tool for the job — whether that's Astro for static-first performance, HTMX for hypermedia-driven interactivity, or plain HTML and CSS when that's all it takes.
