Hi, I'm Constantin Krieg

I worked for 2 years as a Product Designer at Fluctuo, a SaaS startup specializing in shared mobility data. During that time, I contributed to products such as City Dive, a data exploration tool used by cities, journalists, and operators, as well as several internal platforms and B2B dashboards.

Within a small and agile team, I tackled a wide range of design challenges. My work was closely tied to product KPIs, with a focus on usability, client engagement, and overall platform attractiveness.

Aside are a few examples that reflect my design thinking, methodology, and impact on product performance.
