About Me

I am a Business Data Science student at Aalborg University, working toward a cand. merc. at the intersection of analytical methods, software engineering, and commercial thinking — shaped by an upbringing in an entrepreneurial environment and hands-on experience as a board member at Gade og Juul A/S.

My project work spans the full stack — statistical modelling, machine learning, LLM pipelines, and production deployments — with real industry collaborations including Neogrid Technologies, Shaping New Tomorrow, and a formal partnership with Lægehåndbogen & Patienthåndbogen for my clinical NLP thesis.

I approach problems with a goal-oriented mindset and always apply coding in an organisational context — grounded by years working in retail alongside my studies, which reinforced my understanding of how business value is created at every level of an organisation.

My entire education at AAU has been group-based and problem-driven, giving me a strong collaborative instinct and the ability to take ownership of a team's progress. My thesis in clinical NLP brings it all together — rigorous methodology, real stakeholder collaboration, and practical system design in a high-stakes domain.
