Web Design & Development — Case Study
JELON
An AI-powered trading assistant for crypto, forex and stock traders — a marketing site, a trading platform and a mobile app, designed as one clear system.
COMPLEX MARKETS. CLEAR DECISIONS.
Jelon turns raw market data into structured trade ideas. We designed the whole ecosystem — the marketing website and landing pages, the trading platform itself, the mobile app and the account interface — on one design system: dark, precise, and built so a trader can read the market in seconds, not minutes.
Every screen follows the same rules the product does: colour instead of paragraphs, a signal card instead of a cluttered dashboard, and a clear status hierarchy — so what matters is never buried.
