Business oriented backend development with F# at eBay 

eBay is a market leading company within their line of business. eBay owns and runs a long list of online sites within the same segment – online buying/selling of goods and advertising. Examples are BilBasen, BilInfo,, ebay.***,,, Craigslist, BrainTree and lot of other sites.

In Denmark, the business units are joining in the backend systems – some of which are running in Denmark and some abroad.

When migrating the danish business unit from a local setup with a critical backend system, to a distributed cross-cutting solution hosted in the cloud, Strongminds has helped integrate the systems correctly and safely.

Part of the solution was developed in F# in a RESTful micro-service architecture. F# is a functional language with a programming model which supports "no side-effects", shorter development cycles, a more compact codebase and an intelligent data transformation engine.


We're an independent software development and technology business. Our ambition is to be among the top three recognized development houses. Our competitors are big - we're small, efficient and flexible.
