tumnus.
Tumnus is Jakob Berglund. I work with ambitious organizations when they're in the middle of something hard — scaling a frontend team, introducing a design system, or figuring out how engineering, design and product should actually work together. The problems I'm most useful for live in the space between disciplines. I bring technical depth and strategic thinking to the same table.
Services
A few situations where I'm most useful:
When you need technical leadership
Strategic direction, architecture decisions, team coaching, and a clear point of view on what to build and how.
When engineering and product are misaligned
I work at the intersection of frontend, UX and product — translating between them, removing friction, and helping teams move in the same direction.
When you're building a design system
I've built and led design system teams from scratch. I can help you set direction, establish the right structure, and get cross-functional buy-in.
