Senior Engineer 路 Sana Labs
"Amazingly creative and level-headed are words that come to mind when I think about Nils. I had the pleasure of being in a startup with Nils as both a developer and CTO for a year, creating both bleeding edge web and mobile applications. Nils has the ability to quickly grasp problems and consider numerous solutions that helped the team maintain a rapid progress. He was also a great mood lifter with his finger dexterity on the guitar that seems to come effortlessly. Nils would be a true asset to any positions requiring any web based development such as deployment, testing, backend, frontend and has certainly my full recommendation."
