About Me.

Founder and Designer of Balloon inc. (NYC) and Let It Snow ApS (Greenland).

Born and raised in Greenland. I’ve been lucky to find my professional place early (21), in Project Development and breaking barriers through Product Design. It has led me on an international journey to start, close, complete and develop projects in Greenland, Denmark and NYC both in the consumer, enterprise and governmental markets.

Note: My personal site is new and is still missing portfolio projects. Expected completion: Mid May. Contact me for portfolio or visit my LISA agency at https://lisa.gl

daily tools.

As an entrepreneur and designer my daily tools vary, but I usually have Sketch, Framer X, Slack and Trello open. Other tools I often use depends on the project stage which are Keynote, Fabrics, Numbers, Xcode and Adobe After Effects and Photoshop. As a creative I like to try out new tools in the run and I learn really quickly, if not I typically invest in courses on Udemy.
