Lasse Reedtz is a Senior Data Scientist and Machine Learning Team Lead based in Copenhagen with 11 years of experience moving research-grade models into high-throughput production. He specializes in language modeling, transformers and document understanding, leading systems at Visma that analyze over 110 million documents annually and pretrain/finetune large generative models. Comfortable across Python and Kotlin, he combines deep ML research with hands-on engineering from his background in R&D roles at Samsung Display, Tradeshift and enterprise consulting. Lasse is drawn to cutting-edge techniques but stays product-focused, ensuring models deliver strategic value in real-world workflows. An understated strength is his history of shipping end-to-end solutions—from mobile and backend components early in his career to scalable ML pipelines today—making him as effective at integration and delivery as at model design.
