I’m a senior mobile + backend engineer with 20+ years in software (PHP since 2002; professional since 2005) and 10+ years building mobile apps. I help teams ship and stabilize real products—especially apps that are “almost done” but stuck on crashes, performance, flaky networking, or release blockers. What I can help you with (fast, practical): • iOS (Swift, SwiftUI, UIKit): crash fixes, performance/memory, concurrency issues, architecture cleanup • Flutter (iOS/Android/macOS): reliability, state consistency, networking/retry behavior, release readiness • Backend stability (PHP/Laravel or custom, Python/Django, Rails): idempotency, queues, DB performance, webhook safety • Firebase + mobile reliability: Auth/Firestore rules, Cloud Functions patterns, analytics/instrumentation • Monetization + shipping: RevenueCat/IAP reliability, App Store Connect/Play Console, CI/CD, rejection handling Recent work includes taking a messy iOS codebase (CakeClub) to production-ready with a Firebase Cloud Functions v2 backend, stronger security patterns, CI/release automation, and RevenueCat integration; and delivering major cross-platform Flutter work (BillBlaster) including design refinements, admin tooling, and push notification features. If you come with logs/screenshots (Crashlytics traces, network errors, repro steps), I’ll give you a clear diagnosis and a prioritized fix plan—and if it makes sense, I can execute the fixes as a focused sprint.
