Overview
A streamlined, secure trading experience
Optimus Dime is my own live cryptocurrency platform at optimusdime.com, built to give retail investors a streamlined, secure and visually engaging trading experience.
As a personal venture into fintech UX/UI, it covered everything from branding (the name is a playful nod to an “optimised dime”) to the interface for buying, selling and tracking crypto, demonstrating complex application design end to end.
The challenge
Complex, real-time data, made beginner-friendly
The challenge was simplifying very complex, real-time financial data and actions for beginners, while still meeting experienced traders’ expectations, lowering the barrier to entry without losing confidence in security and reliability.

As approachable as a banking app, without overwhelming jargon.
A clear dashboard showing the whole portfolio at a glance.
Easy, low-risk workflows for buying and selling.
Simple, informative charts for tracking performance.
Strong security cues, like 2FA prompts and withdrawal confirmations.
A cleaner, dynamic look that stands out from dark, data-dense trading platforms.
Process
Research, brand, design, test
Domain research
Analysed Coinbase, Binance and Robinhood, and spoke with hesitant would-be investors, whose confusion about charts and fear of mistakes shaped a focus on simplicity, education and error prevention.
Brand & concept
A name evoking optimism (with a nod to Optimus Prime), and a futuristic yet friendly identity: a coin icon combined with a shield, energised by a vibrant green.
Wireframing user flows
Onboarding with educational tooltips, a minimal dashboard of portfolio value, movers and alerts, a clear trade form with a big confirm button, and a Learning Center.
UI design
Responsive web and mobile screens in Figma with plenty of white space, simple charts with advanced data tucked away, human-readable confirmations and a rotating-coin loader.
Prototype & testing
An interactive prototype tested with four users. Novices felt comfortable; experienced traders wanted more detail, so an advanced mode with candlestick charts and an order book was added.
Security & visual cues
2FA and password reset flows, plus restrained green and red price cues that inform without overwhelming.
