Multi Crypto Trading Platform

I’m ready to move from concept to code on a full-featured cryptocurrency trading platform. The core objective is clear: users must be able to trade multiple digital assets in a fast, reliable and secure environment. The minimum viable product therefore revolves around three pillars:

1. Real-time market data – tight latency on price feeds, order book depth and recent trades is essential. Whether you hook into existing exchange APIs, aggregate several sources, or build your own feed handler, the ticker and order book must update instantly without page refreshes.

2. Multi-currency support – at launch I want Bitcoin, Ethereum and at least three additional top-tier coins live, with the system architected so that adding new pairs later is straightforward.

3. Seamless order execution – limit, market and stop-limit orders with immediate feedback on fill status. A matching engine of your own design or a proven open-source core is fine as long as it can scale and pass a basic stress test.

Beyond those pillars I’m happy to phase in extras such as advanced charting or automated bots after the MVP ships, so design with extensibility in mind.

Deliverables
• A web-based trading interface (React or similar) wired to the back-end.
• Back-end services (Node, Go, Rust—your choice) handling authentication, wallets, order routing and matching.
• Real-time data layer using WebSockets or gRPC.
• Postman collection or Swagger docs for every public and private API endpoint.
• Deployment scripts (Docker/Kubernetes) and a short hand-off guide so I can reproduce the stack.

Acceptance Criteria
• Depth of book refresh <200 ms round-trip.
• Successful trades across at least five currency pairs on a staging instance.
• Security review with no critical findings (OWASP top-10 baseline).

If this scope excites you and you have prior exchange, fintech or low-latency experience, let’s discuss timelines and milestones.
