WealthX Trading — VIP Investor Portal

2026

One-liner A members-only investment portal that turns automated trading data, market statistics and AI-written news into a calm, easy-to-read dashboard for VIP clients. Overview I redesigned WealthX Trading from an open course-and-signals website into a closed VIP portal for copy-trading clients. Members get no self-signup; accounts are issued by the team after broker verification. Inside, clients see live performance from our trading EAs, a personal portfolio view, market insight in plain language, and team announcements. I owned the product end to end: UX/UI, front end, back end, database design, data pipelines and deployment. Highlights Live EA performance. MetaTrader 5 accounts report deals and equity through an HMAC-signed API, feeding a performance chart, a profit calendar and key metrics such as win days, profit factor and max drawdown — all from real data. Asset Insight. A daily pipeline (Twelve Data + FRED) computes discount/premium zones, historical probabilities, seasonality and cross-asset sensitivities. An AI model turns the numbers into short Thai/English summaries, with no buy/sell calls. Market Radar. Flags what changed overnight and ranks upcoming US economic events, showing how each asset reacted on past release days. Automated news. Market news is rewritten by AI and published automatically with impact tags. All AI-generated HTML is sanitized before saving and before display. Client care workflow. Watches each copy-trading account for going offline, drawdown, stopped copying and low balance. Admins can send a 3-strike warning by web banner, LINE, Telegram or email. Resilience. Keeps serving the last known good data when the database is slow or down, with timeouts and a read-only degraded mode. Design. A custom "Black Gold Jade" dark theme with reduced-motion support. Bilingual (Thai/English), mobile-first, with hand-built SVG charts. Security and privacy - Login rate limiting and forced password change on first login - Encrypted broker account numbers - Anonymous member IDs - CSRF protection and strict security headers - Audit log of every admin action Role: Product designer & full-stack developer (solo) Status: In private showcase, preparing for first clients
