In developing the investment system, I focused on creating a flexible and user-friendly interface that allows investors to easily manage their assets. Leveraging my extensive experience in product design, I implemented advanced UX/UI practices to ensure ease of use and transparency throughout the process. We designed various investment periods to meet the needs of different types of investors, from perpetual investments to fixed terms of 30, 60, 90, and 120 days. The result is a product that accommodates diverse investment strategies and preferences while ensuring a high level of flexibility and convenience for users.
