I manage Switch/Aghate, a real-time financial app used heavily during market peaks. The moment trading volume climbs, the transaction-processing flow on both our iOS and Android builds crawls—requests that should clear in milliseconds often sit for several seconds. The rest of the app remains snappy, so we know the bottleneck lives squarely in that transaction leg. I need a performance specialist who can trace, diagnose, and remove the congestion that appears during those high-traffic windows. Whether the fix involves server-side tuning, smarter queuing, edge caching, or code-level refactoring on the mobile clients, I’m open, as long as the end result is consistent sub-second performance when users hit “Send.” You’ll have direct access to our current monitoring dashboards, API logs, and a staging environment that mirrors production load patterns. Deliverables I expect: • A concise report pinpointing the root causes of the peak-hour latency • Implemented optimizations (code, configuration, or architecture) pushed to our repo and compiled in both iOS and Android builds • A before-and-after metrics snapshot demonstrating sustained improvement under simulated peak load Once we confirm the numbers hold in production, the project is complete. If this sounds like your specialty, let’s make these waits disappear.
