Our production stack (Laravel API, Flutter mobile app, and a Vue admin dashboard) has started to misbehave and I need a developer who can jump in immediately, trace the roots of each problem, and deliver solid, maintainable fixes within the next 1–2 days. Top priority is the Flutter app because users are being blocked by crashes. Right now I’m seeing all three patterns: • App crashes immediately on load • Crashes when navigating to certain screens • Intermittent crashes during normal usage Beyond that, several API endpoints occasionally return mismatched or incomplete data, the Vue dashboard shows minor layout glitches and sporadic loading stalls, authentication tokens expire earlier than configured, and a few pages feel slower than they should. What I’m looking for from you • Systematic debugging across Flutter, Laravel, and Vue codebases (Git access and staging server are ready) • Clean, well-commented fixes that avoid regressions • Short written summary outlining root causes, code changes, and any follow-up recommendations • Clear, timely progress updates so I can relay status to stakeholders If you’ve handled production-level debugging before and can suggest performance or architectural improvements while you’re in the code, even better. Everything is ready for you to start as soon as we agree. I’ll test changes on staging first, then deploy once we’re both confident nothing else breaks. Let’s get this platform stable again.
