Optimize Booking Slot Monitoring & Response Speed

I’m looking for an experienced freelancer who can help me optimize the performance of a booking/slot-monitoring system. The main issue is that available booking slots appear for a very short period of time, and they are often taken almost immediately. Even though the current system is running fast, we are still missing available slots. I would like an expert to review the current implementation and identify performance bottlenecks, particularly around: * Request/response latency * Monitoring and polling efficiency * Network and server-side latency * Concurrency and request handling * Detection speed when a slot becomes available * Overall application architecture and performance optimization * Reliable handling of temporary errors, timeouts, and rate limits The goal is to make the system as efficient and responsive as possible **while respecting the booking platform's rules and technical limitations**. Please apply only if you have strong experience with high-performance web applications, real-time monitoring, asynchronous programming, and latency optimization. Must have experience without Full Depending on AI Tools In your proposal, please briefly describe similar performance-optimization projects you have worked on.
