What I've Learned

  1. Structuring AI Algorithms

Because a single inventory item affects multiple menus, it was important to design a consistent underlying structure. By collaborating with engineers, I mapped out what data existed, how it functioned, and where it applied, breaking down and organizing the system step by step.

  1. Rapid Prototyping & Design Iteration

Working in a fast-paced startup environment, I focused on rapidly turning ideas into prototypes and refining them through iteration. Instead of aiming for perfection upfront, I prioritized quick experimentation, learning from feedback, and improving designs in cycles. By working closely with engineers throughout this process, I was able to evolve solutions efficiently while keeping the user experience at the center.

  1. Internal A/B Testing

In early-stage MVP conditions with limited real users, I learned the value of conducting internal A/B testing. Testing with team members helped us move beyond fixed perspectives and maintain a more objective view while iterating on the product.
