Overview
Apex Platinum is an ultra-premium fintech platform for a licensed Electronic Money Institution (EMI) based in Vilnius, Lithuania. It combines a visually immersive public marketing site with a simulated institutional dashboard — covering SWIFT/SEPA payments, correspondent banking, merchant acquiring, crypto exchange IBANs, multicurrency accounts, and a private wealth concierge experience.
01 · Problem
Institutional fintech platforms need to convey trust, sophistication, and regulatory credibility while delivering complex financial data in an intuitive interface. Off-the-shelf templates fail to communicate the premium positioning required for high-net-worth and institutional clients.
02 · Strategy
Build a visually stunning, enterprise-grade fintech portal that serves as both a conversion-optimized marketing site and a simulated institutional dashboard — showcasing portfolio management, vault custody, market terminals, and concierge advisory.
03 · UX
Interface and workflow priorities: Immersive landing with shader backgrounds, Hyperspeed effect, and Lightfall particles; 7 solution pages covering payments, banking, accounts, e-shop, financing, and crypto; 4-tier pricing (Business, Business Plus, Business Exclusive, Individual).
04 · Development
Architected and built the entire platform — from 3D shader backgrounds and Hyperspeed effects to the institutional dashboard with portfolio visualization, vault custody ledger, and market terminal. Implemented dark/light theming, smooth scroll, and page transitions.
05 · Challenges
Balancing heavy 3D visuals (Three.js, OGL, postprocessing) with page performance — required careful dynamic imports with ssr: false. Creating a design system that feels genuinely premium and institutional rather than template-like.
06 · Business impact
Delivered a production-ready fintech platform with 14+ routes, immersive 3D visuals, and a complete institutional dashboard simulation that convincingly demonstrates wealth management capabilities.

Takeaways
Premium fintech UI requires obsessive attention to micro-interactions, typography, and color — small details (metallic shine, brushed platinum textures, scan line animations) create the perception of institutional quality. Dynamic imports are essential for Three.js-heavy pages.
