About Me.

Product strategist from 10 years of experience in Product Management and 8 years of Product Design across a series of organizations and teams.

I am a highly motivated cross platform product manager and an advocate for agile methodologies with a deep experience working both in and with large organizations and in startups. I have a passion for working on new products and strategies across users, designers, developers, analysts and leaders.

Born and raised in Greenland. I’ve been lucky to find my career path early (21) in project management and breaking barriers through product design. My natural interests led me on an international journey to start, close and complete software projects in Greenland, Denmark and NYC both in the consumer, enterprise and governmental spaces, eventually making me an experienced product strategist.

We Are From Nuuk

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.
