Senior AI Engineer at Heyra

Interactive version: laufrandsen.dk

Designing and building AI and ML systems end-to-end, from problem to prototype to production. I build both purely agentic flows and traditional ML wrapped in agents, delivering the real AI experience: chat with your data and get predictive insights from the same system.

Passionate and results-driven AI Engineer & Data Scientist with a solid background in software development. As both a Data Scientist and Team Lead on a DSB x Netcompany project, I took part in developing and implementing AI-driven predictions for Danish trains, a solution with customers in all of Denmark. That experience taught me to run Proof of Concept projects and scale them into machine learning solutions that deliver tangible business value through productionised models.

I have worked with traditional ML such as predictive maintenance, data clustering, classifiers, time-series prediction and regression, as well as Deep Learning, where my expertise has been computer vision. I have strong experience with LLMs, including agentic workflows, document extraction and LLM evaluation.

I thrive in collaborative teams, using a strong technical foundation and a versatile skill set to move projects forward. I'm proactive by nature, taking initiative so goals are met and obstacles are dealt with promptly.
