We’re looking for an experienced developer to improve an existing exchange platform built with React, TypeScript and Cloudflare.
Our priorities are faster market loading, reliable price and liquidity updates, and a polished frontend. The current version uses REST; previous streaming experiments need reviewing before choosing the right architecture.
Scope: - Audit the existing code, API integration and market-data flow. Source code and technical documentation are available. - Recommend REST, streaming or a hybrid, with a clear architecture and milestone plan. - Implement the approved design for market data and server-side order handling. - Reduce loading times and improve frontend navigation, responsiveness and stability.
Performance targets will be agreed after the audit and verified in staging, covering loading times, data freshness, smooth updates and reliable order handling.
Please share one or two relevant Exchange API projects, your approach to the audit and your availability.
We will start with a short audit with an agreed hours cap, followed by separately approved implementation milestones.
