About

Sturnus Engineering was established in 2003 and with the exception of a small break in 2018-2020 the Company has been active for 15 years.

I also worked periodically as an employee and thus offer 25+ years of  experiences from multiple business, including several patents and a bag full of evaluation and calculation tools.

Please see some product examples and descriptions below.

Kind Regards Lars Stæhr
