Cases & testimonials §

I’ve built a prototype for a client in a research project, to search through scans of pages from 18th century newspapers. Both text extraction and cleanup, as well as the search engine itself, were built around LLMs as a central component.

Cloud migration for Boligsiden §

I was a leading consultant for moving Boligsiden to a cloud-based system, enabling faster development of the product and better use of all their real estate market data.

Markus’ technical proficiency and excellent communication skills make him a cornerstone of any software development team.

He is able to single-handedly own key deliverables, working alongside product owners to understand business needs, and ensuring that they are implemented on schedule in a technically sound manner.

He works across the entire software development lifecycle. From the nitty-gritty details of coding and data modelling, to architecting and implementing cloud infrastructure, to operational excellence and sensible processes.

Working with Markus is a pleasure, and I would highly recommend any team looking to deliver serious software to onboard Markus.

Storage Infrastructure at Uber §

I worked as a software engineer on the storage platform team at Uber. My main responsibilities were to build and run software to automatically operate Uber’s realtime storage systems at scale.
