Hey there, I’m Andreas.

I’m an independent software engineer living in Linz, Austria.

I am a fan of creating well-designed, scalable and reliable Backend systems that stand the test of time.

This is achieved by using the appropriate technologies for the case at hand that allow for great productivity and a fast time to market.
