SELECTED PROJECTS

The projects below are the clearest examples of how I work. Each one combines product decisions, implementation detail, and technical ownership under real constraints.

E-Commerce solution

Cocoon Company Ecosystem

Lead Developer / Full Stack Developer

Saw a revenue increase of +102.2%, order increase of +183.5%, and growth from 2 to 5 webshops.

The current role is not just frontend work. It is ownership across storefronts, operational tools, and ongoing growth.

Design and development foundation

The period where the fundamentals were built: shipping websites, learning by doing, and getting comfortable handling both design and implementation.

  • Developed the instincts that later scaled into broader ownership.
