Cases & testimonials §

Videlicet is system to enable researchers to extract information from and search in 18th century American newspapers. It allows them to experiment with custom information extraction prompts, run custom evaluations, and makes extracted information searchable.

Seekerbase is a search engine and data platform I built for the company of the same name. It allows searchers to find products and manufacturers to administrate products on this two-sided marketplace platform.

Markus has been absolutely brilliant in taking our idea to reality. At Seekerbase, Markus combined strong technical skills with a practical, no-nonsense approach. He turned complex requirements into clean solutions and kept everything on track. Markus is reliable, clear, and excellent at his work.

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.

Cloud migration for Ejendomstorvet §

I was a consultant for Ejendomstorvet, providing architectural strategy and implementation work to modernize the platform and move it to the cloud.

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.

Constantly meeting deadlines, working hard to improve the stability and quality of our products, Markus is a high performer and a great example for others.
