AVA—A Vital Archive—is already live on both the Apple App Store and Google Play. I now need a dedicated partner to keep the app running at its best and to shepherd every update through to release. My immediate priority is performance optimisation, so your first weeks will focus on diagnosing slow spots, reducing crashes, and ensuring smooth operation across the latest iOS and Android versions. Once the core issues are ironed out, I’d like you to take ownership of routine maintenance, including store-listing updates and compliance checks, while keeping me in the loop with clear, jargon-free status reports. Key responsibilities • App maintenance & updates • Performance optimisation (profiling, refactoring, resource-usage tuning) Ideal experience You’re comfortable digging into both Swift and Kotlin/Java projects, reading store analytics in App Store Connect and Google Play Console, and shipping incremental releases through TestFlight or closed testing tracks. Familiarity with Firebase Crashlytics, Instruments, Android Profiler, and similar tools will help you hit the ground running. Deliverables for our first milestone • A concise performance audit highlighting bottlenecks • An optimisation plan with estimated effort and measurable targets • A patched build submitted to both stores passing review If this sounds like the kind of long-term technical stewardship you enjoy, let’s talk about timelines and how you’d tackle the initial audit.

Hello, this is exactly the kind of long-term app stewardship I specialize in. Maintaining and optimizing a live iOS and Android app requires structured profiling, disciplined refactoring, and careful release management. Here’s how I’d approach AVA’s first milestone: Phase 1 – Performance Audit (Week 1–2) • Review crash logs in Firebase Crashlytics • Analyze App Store Connect & Play Console metrics (ANR, cold start time, memory spikes) • Profile using Xcode Instruments and Android Profiler • Identify UI thread blocking, excessive network calls, memory leaks, and inefficient rendering You’ll receive: • A concise audit report highlighting bottlenecks • Clear metrics (startup time, crash rate, memory footprint) • Prioritized optimization roadmap with effort estimates Phase 2 – Optimization & Patch Release • Refactor heavy components (Swift / Kotlin) • Optimize API calls and caching • Reduce unnecessary background tasks • Submit patched builds via TestFlight and Closed Testing Ongoing responsibilities I can own: • Regular dependency updates • Store compliance monitoring • Listing optimization • Incremental release management • Clear, jargon-free monthly performance summaries I’m comfortable working across native Swift and Kotlin projects and maintaining clean, production-grade builds. Let’s open the chat. I can outline a 30-day stabilization plan and confirm availability for long-term maintenance. Best, Jenifer

Hi, I will build your mobile application with the core user flows, backend API, and deployment to both app stores. The app will handle authentication, data sync, and push notifications. I will architect the app with offline-first capability where critical data is cached locally so users are not blocked when connectivity drops. Questions: 1) Do you have an existing backend/API, or does that need to be built as well? 2) Are there any specific third-party integrations required? 3) Do you have the Apple Developer and Google Play accounts ready? Looking forward to potentially working together. Thanks, Kamran

Hello, AVA sounds like a meaningful project, and maintaining a live mobile app while improving performance across both platforms is something I’d be glad to help with. Ensuring stability, reducing crashes, and keeping releases smooth is essential for user trust and store compliance. For the first phase, the focus would be a complete performance audit of the current iOS and Android builds. This includes reviewing crash reports, profiling resource usage, and identifying slow or unstable components. Tools such as Firebase Crashlytics, Instruments, and Android Profiler can help pinpoint memory issues, heavy network calls, inefficient rendering, or background processes that affect performance. After the analysis, I’ll prepare a clear optimization plan outlining the main bottlenecks, recommended fixes, and measurable improvements such as reduced crash rate, faster load times, and better memory usage. Once approved, the necessary refactoring and tuning will be implemented, followed by testing and submission of an updated build through TestFlight and Google Play testing tracks. Beyond the first milestone, I’m happy to support ongoing maintenance, manage store updates, monitor analytics, and provide clear progress reports so you always know the app’s status.

Hi I specialize in stabilizing and optimizing live mobile apps, focusing first on measurable performance gains before moving into long term maintenance ownership. I am comfortable working in both Swift and Kotlin codebases, reviewing crash logs in Firebase Crashlytics, and profiling with Instruments and Android Profiler to identify memory pressure, UI thread blocking, excessive re renders, and network bottlenecks. For the first milestone, I will conduct a structured audit covering crash frequency, startup time, screen rendering performance, background task handling, and API latency. You will receive a concise report outlining root causes, prioritized fixes, and clear performance targets such as reduced crash rate, improved launch time, and smoother frame rendering. After alignment, I will implement patches and submit updated builds through TestFlight and Google Play testing tracks, ensuring compliance and clean store review. I value long term technical stewardship with clear, jargon free updates and predictable release cycles. Best, Justin

I’d start by running a detailed performance audit using Instruments and Android Profiler to pinpoint the main slow spots and crash sources on the latest iOS and Android versions. From there, I’ll create a clear optimization plan breaking down tasks, expected effort, and how we’ll measure improvement. Based on similar work on a live hybrid app, quick wins like memory leaks and inefficient database queries drastically cut crashes and boosted smoothness in under two weeks. For your first milestone, I’ll also prepare a patched build with fixes for key bottlenecks and get that through TestFlight and Google Play’s closed testing without hold-ups. To keep updates steady and transparent, I suggest using simple weekly reports focused on app health and release checkpoints to keep you fully informed without jargon. Do you have particular crash patterns or slow screens you’ve seen frequently in store analytics? Also, would you prefer me to prioritize critical crashes over minor performance tweaks initially, or balance both from the start? Ready to start the audit and have a first draft plan within a few days.
