I am a machine learning / AI applied scientist, engineer, and basketball player. I am interested in the complete lifecycle of learning-based systems from research to development, deployment, scaling, and improvement. I have worked with the full spectrum of data (tabular, graph, language, image, video, and 3d), and have developed various discriminative and generative models from LLMs to diffusion operating on such data.

I studied computer vision at NTNU and completed my MSc thesis on unsupervised image segmentation at KU Leuven. Then, I had a PhD adventure at TU Delft, where I worked on fast registration algorithms for incomplete point cloud data.

Previously, I led the research and development of deep networks for automated image editing and the architecture of the ML cloud infrastructure at one of the leading visual content companies, Bright River. You have definitely seen my models in action on your favorite e-commerce website. Later, I worked on massive ML systems for measurements, analytics, and ad fraud at Bol, the largest online shop in the Benelux.

I also sometimes write about ML & AI at InfoQ, you can check out my articles here.
