About
I’m Matej Marić, a machine learning engineer based in Zagreb, Croatia. I build end-to-end CV/ML systems, from data pipelines and model training to production inference, with a focus on reliable, scalable solutions for real-world footage and imagery. Most recently I worked on a photography-detection system for a museum and on backend ML services for a retail app.
I enjoy turning complex data problems into maintainable software, collaborating with cross-functional teams, and applying ML to wildlife monitoring and conservation as well as digital experiences.

Work experience
Built a photography-detection system for a 16-camera museum setup, combining YOLO person/phone detection, pose estimation, ByteTrack, and homography mapping to place events on a shared floorplan, plus other CV-based solutions for camera footage analysis. Trained and tuned the event-classification stack: pose-feature extraction, XGBoost pose classifier, plus temporal voting and orientation logic to make detections usable on real footage.
Built and maintained backend ML services for a retail app where users capture store-shelf photos for item detection/classification. Improved model performance through dataset curation, annotation refinement, retraining, and systematic benchmark/evaluation comparisons. Researched and prototyped experimental features, then integrated selected improvements into production backend workflows.
