Summary

I led the UX/UI design for the project, collaborating with brand design, illustration, and animation teams to ensure a cohesive and engaging user experience.

My role included working closely with the engineering team to understand the complexities of cryptocurrency, arbitrage, and trading, ensuring the platform was functional and user-friendly. I conducted extensive stakeholder and user interviews to align the project with user needs, creating detailed personas and identifying key features. I also managed the design and delivery of illustrations, animations, and videos, coordinating with both internal teams and external freelancers. Throughout, I employed a user-centered approach, continuously validating and refining the design to deliver an intuitive and effective product.
