That’s how Double looked like when I’ve joined and started working on in January, 2024.
Strategy CustomizationActivityDeposit MoneySimulation Overview
My initial plan was to create and implement the most essential features the platform needed. However, as a side project, I also started working on small adjustments and improvements that would provide long-term benefits.The platform's look and feel should remain consistent throughout, creating a seamless, cohesive experience. It should feel like a unified system, not a collection of disconnected elements that evolved out of necessity.
There’s no mobile version, and essential features like Settings and Notifications are missing—both of which are standard and crucial for any product.
From Chaos to clarity
With limited resources, I gradually started working on the design system while simultaneously handling new feature requests.
My primary focus was on these new features—let’s say about 75%—while building the design system in parallel. The new system needed to be more flexible and seamlessly integrated into our design language.
Systems aren’t built overnight—they require continuous testing, iteration, and refinement. Every system evolves through multiple updates and improvements, demanding careful attention from designers to ensure it remains effective, intuitive, and user-friendly.

Strategy Card
The strategy preview should be clear, informative, and instantly valuable to users. Since we are new to this industry, it's crucial to present key information at a glance, ensuring users get what they need immediately.
That should include essential details such as risk level, minimum investment, top sectors, top holdings, expected returns, and a brief description.
Additionally, it should be clear that more in-depth information is available by clicking on "Details".
Also, I’ve created 50+ special covers for strategies.
Every strategy has it's cover image showing the main information, it's very useful to see the whole important information just right away.
Strategies
The main getaways on a strategy page are:
1. Headers of the categories are way too small
2. Naming of the strategies in the card are different, they are hard to fit properly into card, it jumps
3. Everything is a little bit mess, hard to navigate
4. Very hard to distinguish one sector from another
How to avoid previous problem and make it more cleaner for the users that is browsing for the first time, and what I did there? (See version 2)
1. Updated cards, now they are looks much more clean with bigger image and clean name on the top
2.
Applied background to the sections to make it more visible, also added extra padding for the category headers
3.
Removed horizontal scroll, now all cards fit into container
Smooth Pusher to Sign Up
We want a welcoming approach, avoiding aggressive tactics like intrusive modals or blockers.
Instead, we gently remind users that signing up unlocks more features and a better experience. To achieve this, I introduced a subtle sliding block that appears as users scroll down—providing a seamless nudge without disrupting their journey.
Plus, they can easily dismiss it anytime.
A few additional modals were implemented to help people be more active and tell other people about our platform is to share what they have.
Mobile
As Double continues to grow, users are increasingly requesting mobile access.
Now that the core app is established, our developers and designers have collaborated to create a seamless and intuitive mobile experience.
