Fullstack Software Engineer — Munich

Software that runs. And gets found.

I build scalable microservices and AI agents at Check24 Factory. Here I show both sides: how I architect systems — and why they stay invisible to both humans and AI models without SEO and llms.txt.

About me

Fullstack Software Engineer focused on scalable microservices and high-throughput web applications — built with Go, Node.js and PHP (Symfony), complemented by modern frontend frameworks. Currently at Check24 Factory, responsible for architectural decisions, asynchronous message queuing, and AI-driven workflow automation.

Previously: end-to-end development at Vivid Planet Software and frontend work at Eyedea Werbe. B.Sc. in MultiMedia Technology (FH Salzburg), focused on web technologies and human-computer interaction — where my interest in how systems get read by humans and machines started.

My second specialty

Why SEO & llms.txt matter now more than ever

The best code is worthless if nobody finds it — neither humans via Google, nor assistants like ChatGPT, Claude or Perplexity. That's my second field: building systems that stay readable, citable and discoverable for both search engines and language models.

Classic SEO isn't dead

Crawlability, Core Web Vitals, semantic HTML and structured data (Schema.org / JSON-LD) still decide whether a page shows up in Google at all.

New: llms.txt as a second front door

llms.txt is an emerging standard — akin to robots.txt and sitemap.xml — that gives AI systems a curated, plain-markdown overview of a site's key content. No navigation, ads, or JS rendering to slow crawlers down.

  • Visibility in AI Overviews, ChatGPT answers & Perplexity citations
  • Accurate, current information instead of outdated or hallucinated summaries
  • Less rendering overhead for crawlers & agents → better odds of indexing
  • Future-proof: search behavior is measurably shifting from classic SERPs to conversational interfaces

This page practices what it preaches: semantic HTML, a Person schema (JSON-LD) in the source, a bilingual hreflang setup — and a real, live /llms.txt.
