Unified Trades & Payments Platform Systems

I’m building a single online hub where users can trade assets and move money without jumping between services. The vision is to pull together proven capabilities from leading payment gateways, stock-trading APIs and crypto exchanges, then layer on a set of custom tools that make the experience faster, safer and more insightful than anything that’s out there today.

What I need from you is the full build: database design, secure API layer, responsive front-end, real-time data feeds, trade execution, and friction-free fund settlement. I’m flexible on the exact mix of third-party integrations as long as they are reliable, well-documented, and give us the essentials—instant deposits/withdrawals, live market quotes, and swift order routing.

On top of those integrations, you’ll craft features such as portfolio analytics, advanced charting, role-based user controls, a multicurrency wallet, and a switch-friendly admin console so modules can be enabled or disabled without touching code. Security has to be airtight: encryption in transit and at rest, 2FA, audit logs—the works. Scalability matters too; the architecture should accept new asset classes and traffic spikes without rewrites.

Deliverables
• Clean, well-commented source code (back-end & front-end)
• API documentation and a concise setup guide
• Deployed staging environment for my review
• Final hand-over session so I’m fully comfortable operating and extending the platform
