ChartHustlez — Trading Platform UI
Pro-grade trading dashboard with custom charting engine, Stripe subscription billing, and real-time market data API integration. Built to compete with Bloomberg Terminal aesthetics.
Proof of Build
Systems we've deployed. Results we can measure. Every project starts with intent and ends with working software.
Four builds. Four different system types. All shipped on schedule.
Pro-grade trading dashboard with custom charting engine, Stripe subscription billing, and real-time market data API integration. Built to compete with Bloomberg Terminal aesthetics.
Zero-trust authentication overhaul. CSP headers, parameterized queries, rate limiting, MFA, and pen-test-ready infrastructure built in from day one.
End-to-end workflow automation bridging Stripe, Airtable, and Slack. Custom webhook orchestration, error handling, and audit trail logging. Zero manual intervention.
High-conversion SaaS landing page with Three.js hero scene, GSAP scroll-pinned sequences, and A/B tested CTA architecture. Built for lead generation at scale.
Client needed a professional-grade trading interface that could compete with Bloomberg Terminal aesthetics — without the six-figure enterprise price tag. Existing solutions were generic, slow, and failed to convey trust to serious traders.
The brief: build a subscription-based trading dashboard with real-time data visualization, a custom charting engine, and a Stripe-integrated billing layer. Timeline: 14 days to MVP.
The visual target was command-center grade — dark interface, dense data density, zero wasted pixels. The system needed to feel like a professional tool, not a consumer app.
Stack: Vanilla JS + Vite for the build system, custom canvas-based charting engine for performance-critical price rendering, Three.js for the hero visualization layer, and GSAP for all UI transitions.
Stripe integration handled subscription tiers, checkout, and webhook-driven access control. The dashboard itself used a custom layout engine — no CSS frameworks — to achieve sub-12ms render times on complex data grids.
Security hardening was baked in from day one: CSP headers, input sanitization, rate-limited API calls, HTTPS-only delivery via Vercel Edge Network.
Deployed on day 14. Zero post-launch critical bugs. Stripe subscription flow converted at 2.3x the previous static landing page.
Lighthouse scores: Performance 96, Accessibility 94, Best Practices 100, SEO 100. First Contentful Paint under 0.8s on Edge Network. Total Blocking Time: 0ms.
The platform runs live at charthustlez.online with active subscribers on the Pro tier. The client received full source code, Vercel project access, and a handoff document on day 14.
404 Labz handled the full stack: visual design, component system, custom charting engine, Stripe integration, security hardening, and production deployment.
No third-party design tools. No UI component libraries. Every pixel, every animation, and every integration was built from scratch to match the client's command-grade brief.
Post-launch: provided 2 weeks of monitoring, bug resolution, and feature iteration included in the original scope. Client owns the full codebase and Vercel project.
