Hi, Kareem here. Your priority is stabilizing and hardening a live Java backend for a taxi-hailing platform—improving reliability and efficiency without disrupting working Flutter apps or the website. I’ll focus on server-side diagnostics, performance tuning, and targeted bug fixes, with careful profiling to remove bottlenecks and reduce error rates. I’ve maintained and optimized production backends in Java (Spring) with real-time workloads, applying caching, async processing, safer concurrency, and observability to improve uptime. I propose starting with Phase 1: backend audit (logs, hotspots, DB queries, API latency), then rolling fixes and efficiency gains behind feature flags. Changes will be regression-tested to ensure zero client impact. Let’s align on current pain points and SLAs. I can start immediately.
