Freelance engineer, founder of Studio Nordwerk
I build small, quiet software.
I'd rather ship a few things that are finished than many that are loud. After ten years of software for others I now also build my own, and I still work freelance, currently for a large European beauty retailer and a marketing attribution company.
I can build and I can sell, but not both at once. So I am looking for founding partners who take on the selling.
