Project description:
"Our live ride-hailing platform is showing some stubborn stability issues on both the PHP backend and the Kotlin Android codebase. I need an experienced developer who can dive straight into our Git repo, trace the root causes, and roll out solid fixes without disrupting active riders and drivers.

Here’s what you’ll find when you arrive: the full Laravel-based admin and API, a Kotlin rider/driver app pair, staging and production environments, and access to recent crash stacks from Firebase along with my own notes on how to reproduce the most frequent failures. Your task is to isolate the offending logic, patch it, push reviewed pull requests, and confirm the fixes on staging before I promote them to production.

Deliverables
• Debugged PHP backend and Kotlin client code committed to Git
• Clear changelog explaining the fixes
• Final APK for testing plus a short deployment guide

Acceptance criteria
1. No repeat crashes after 48 hours of staged load testing.
2. GPS, payment, and trip-state flows behave consistently from login to trip completion.
3. Backend logs stay error-free under normal traffic.

If you’ve already wrangled complex, real-time apps and you’re comfortable profiling both server-side PHP and Android Kotlin, let’s get moving—I’m ready to give you repo access today." (client-provided description)
