About

Structured, engaging and curious – I combine deep mathematical training with modern software engineering and AI integration.

I am an experienced mathematician with a strong background in teaching, data analysis and software development – with a particular focus on the practical application of artificial intelligence (AI).

After more than a decade teaching mathematics, I formalised my passion for technology through a Datamatiker degree and specialised courses in AI integration and MLOps. Today, I lead AI-Dev Solutions ApS, where I design and implement AI-supported systems that create real value for learners, teachers and small businesses.

I thrive in cross‑disciplinary teams, translate complex theory into intuitive solutions, and always keep ethics, pedagogy and GDPR at the centre of every AI product.

Beyond the keyboard

When I am not working with AI and software, I spend time with my husband and our three children. Sport is an important part of my life – I love cycling, running and playing football.

I also enjoy reading news and staying connected with friends around the world on social media. Chess is another favourite – a way to challenge my brain and explore new strategies.
