Frontend developer — UI/UX design and implementation.

The Story

The Challenge

Poolder needed an internal platform to run its DeFi trading the way the company actually works: trading managers issue orders, traders execute them, and other departments — compliance among them — step in to do their part. Each of those roles needed its own user flow, designed around what that stakeholder actually does.

On top of that, it had to be genuinely easy to use, with an intuitive interface — and it had to pull information from multiple sources into one place, so traders could make the best possible decision without hunting for data.

The Approach

I started with the people who'd use it. Through multiple interviews with the different stakeholders, I mapped out what each role needed from the platform. To validate those ideas before any code, I built draft interfaces in Figma — and before that, researched UI libraries to find the right fit for the end users. Further interview sessions refined the flows and screens until the MVP scope was agreed.

From there, the build began, with me responsible for the UI and frontend — turning the validated designs into a working, intuitive interface.

The Outcome

A working internal trading platform that brings managers, traders, and compliance into a single, structured workflow. Orders move clearly from manager to trader, each department has a flow built around its real tasks, and key information from multiple sources is surfaced in one place — giving traders what they need to make informed decisions, in an interface designed to stay out of their way.
