The Personality Database Platform
Personality Database marks my transition from architecture to product design, in which I had the opportunity to lead a large-scale project from the ground up, with full creative freedom to shape its structure, experience, and identity.
Everything that irritates us about others can lead us to an understanding of ourselves
― Carl Gustav Jung
Everyone lives in their own universe, longing for love and understanding.
We hope to create a community where people not only discover themselves, but also find the courage to explore the worlds of others.
The Double Diamond Model serves as our guiding framework throughout the design process. Our approach follows these key steps: first, we analyze the market and users, then narrow down the problem, and finally, apply creative solutions to address specific challenges effectively.
80% of PDB users are Gen Z. To define PDB’s market position, we conducted research on their favorite social media platforms and psychology-focused websites, identifying key engagement trends and user behaviors.
