AI Engineer & Data Scientist
Building intelligent
systems at scale
I'm Jörg — a physicist turned engineer with a decade of experience shipping AI-powered products, from search systems handling millions of queries to production ML pipelines.
About
Where physics
meets engineering
With a PhD in Statistical Physics and years in the trenches of large-scale tech, I bring analytical rigour to messy real-world problems. I've led engineering teams, built AI search from scratch, and shipped systems that directly move business metrics.
Currently freelancing from Tenerife, working with companies that need senior-level AI and search expertise — from architecture to production code.
What I do
Domains of expertise
AI Search
Natural language search systems with semantic understanding, vector retrieval, and RAG — from prototype to production at scale.
ML Engineering
Machine learning models that ship. Price prediction, ranking optimisation, click-through forecasting — validated through rigorous experimentation.
System Architecture
Cloud-native microservices on GCP and Azure. Technical leadership for teams building high-performance, data-driven platforms.
