Why I built Lumina

I work in SEO and web development every day — managing websites, running audits, optimizing for search engines, and increasingly, for AI-powered search. I kept switching between five different browser extensions, browser tabs, and tools just to get a complete picture of a single page.

Lumina started as a personal tool to solve that problem. One extension that gives me everything I need: on-page checks, SERP preview, schema validation, AI crawler analysis, Google Search Console data, GA4 insights, keyword research, and AI-powered content tools.

I made it free because the best SEO tools shouldn't be locked behind expensive subscriptions. Your API keys, your data, your browser — no middleman.

What I do

I'm the Web Development Lead at bazuba, a bathroom renovation company with 20+ franchise locations across Austria, Germany, and Switzerland. I'm responsible for the website, UX, SEO, GEO (Generative Engine Optimization), and digital marketing — from Google Ads to tracking infrastructure.

Previously, I worked as a GEO & SEO Consultant at Otago Online Consulting, one of Austria's leading digital marketing agencies and a Google Premier Partner. There, I focused on SEO strategy, GEO innovation, and presented on topics like AI Overviews and AI Mode at the Otago Summit.

Beyond tech, I serve as a Gemeinderat (municipal councillor) in Mödling, Austria — working on finance, legal matters, and local governance as part of a governing coalition.

Skills & expertise

I work at the intersection of web development, search optimization, and AI — building tools and strategies that bridge all three.

Connect

I'm always happy to hear from SEO professionals, developers, and anyone interested in GEO. Feedback on Lumina is welcome — it's how the extension keeps getting better.
