"Progress is when yesterday's magic becomes tomorrow's infrastructure."
PhD in biophysics. Today I build AI that runs inside SAP landscapes: ABAP coding agents on BW/4HANA, RAG over SAP data, LangGraph pipelines on SAP AI Core.
I like systems that behave predictably, and complexity that earns its keep.
Methods from super-resolution microscopy, published in Nature-family journals and BMC Bioinformatics.
Compressed sensing plus CNNs for confocal dSTORM. Handles corrupted PSFs that break standard fitters.
Image registration, structure analysis and automated quality control for microscopy data, with nanometer precision.
Coding agents that write and test ABAP on BW/4HANA. RAG over SAP data on AI Core. Deployed, not demoed.
From research prototypes to production systems
Production Sports Analytics Platform
Endurance sports platform with ML-based performance prediction and training analysis. Live at endurexai.de.
AI for Scientific Imaging
Compressed sensing plus deep learning for confocal lifetime localization microscopy. Recovers emitter positions from irregular PSFs. Published in BMC Bioinformatics.

Have an SAP landscape and an AI idea? Bring the problem. I'll tell you honestly whether it is a two-week proof of concept or a bad idea.
