About HLL

Häggander Liden & Lundberg Computer Systems (HLL) was founded in 2000 as a company where the founders shared ownership of a patent. The founders soon started to get frequent requests to work as consultants. Rather soon, the company pursued this change of direction. By employing well known software developers, the company turned into an expert consulting company. Our innovative, talented and often very experienced staff is mainly working on consultant assignments targeting the Software Engineering industry.
