Summary
👤
Senior🎓
Top SchoolMathieu Orhan is an AI Research Engineer based in Paris with nine years’ experience building production-ready ML and computer vision systems. He has progressed from deep learning scientist roles into senior research and manager positions, leading core research teams and delivering high-impact engineering such as 10x inference speedups and large-scale training and inference infrastructure on AWS and TPUs. Mathieu combines hands-on modelling—residual error analysis, synthetic data engines, multi-view geometric reasoning and GNNs—with ML Ops expertise to turn research into robust, explainable products that enabled full automation and multi-million-dollar savings. He has a strong track record in document understanding and OCR (boosting text detection from ~60% to 99% on noisy Japanese faxes) and in multi-view vehicle damage assessment. Trained at École normale supérieure Paris-Saclay and École des Ponts, he blends rigorous academic foundations with pragmatic product-driven experimentation. Colleagues would note his appetite for principled problem framing and for improving tooling and pipelines that raise team velocity and reproducibility.
