My cross-platform AI-driven mobile app is suffering from performance issues that trace back to the data layer. On both iOS and Android, new records intermittently fail to save, and previously stored data sometimes disappears or reappears only after a forced refresh. This “database and saving” problem is the root cause of user-visible lag and occasional freezes when the app attempts to read or write. What I need: • Pinpoint why data is not saving correctly in the current database implementation and resolve it without breaking existing features. • Optimise the read/write cycle so that loading screens and UI interactions stay smooth even under poor network conditions. • Ensure fixes work consistently on the latest production versions of iOS and Android, then regression-test earlier OS versions we still support. • Provide a concise technical summary of the root cause, the changes made, and any future maintenance recommendations. Acceptance criteria: 1. New and existing records must save and sync reliably on both platforms after multiple stress-test cycles. 2. Average write and retrieval times should drop to an acceptable threshold agreed during kickoff (benchmarked with real-world sample data). 3. No new crashes or memory leaks introduced, verified with Xcode Instruments / Android Profiler (or equivalent). 4. Final build passes store-submission automatic checks for iOS App Store and Google Play. Code access is ready in Git, plus a small test suite you can extend. Most of the stack is documented; any gaps can be clarified quickly. Once the fix is in place, I’ll take care of redeploying to production—just need a stable build and your implementation notes.

DB profiling on a cold app usually surfaces 80% of the load time in 3-5 queries. Fixing those gets you a meaningful speedup without touching application logic at all. My plan: pull the slow query log, find the actual bottlenecks (N+1 loops, missing indexes, unbounded fetches), then fix them with targeted changes: indexes, query restructuring, pagination where it's missing, and light caching on the hot reads. Every fix gets a before/after benchmark, so you're looking at real numbers instead of taking my word for it. Deliverable: diagnosed and fixed DB layer, with documented before/after query performance. 3 days, 11,000 INR, single milestone. Are slow query logs already enabled, or is enabling them the first step?

Hi! The bit about records “disappearing or reappearing only after a forced refresh” is a classic fast-write/slow-sync race. I’ve fixed similar sync and data-loss bugs in AI mobile apps—often it’s how transactions or cache writes are queued, not just one database call. I’d start by tracing save/refresh logic in the current app, stress-testing edge cases using your test suite. I’ve handled the same for production AI apps built with React Native and Flutter, where fixing stale reads and lowering write latency meant big drops in UI lag. Quick question: is all data stored locally first with sync to a backend, or is some data meant to be cloud-only? This shapes how I’d target the patch. Happy to dig in and share a no-strings report of what’s breaking underneath. Similar fixes and demos are shown at work.techindika.com. — Pradeep

Read the brief — cross-platform AI mobile app with a data-layer regression: intermittent write failures + stale-read symptoms, user-visible lag tracing back to the database/sync path rather than UI thread blocking. Approach: pick up your Git + test suite, instrument writes with structured logs (op id, timestamps, retry path), reproduce on iOS + Android under throttled network. Most 'disappearing data' cases we've debugged trace to swallowed transaction errors, race conditions between local cache and remote sync, or stale offline-queue replays. Pinpoint via Xcode Instruments + Android Profiler, then patch with proper transaction boundaries + idempotent sync. Debugged similar RN/Flutter data-layer issues for production apps — same fingerprint. Deliverables: root-cause writeup, patched code on your Git, regression suite extensions, store-submission-clean builds. Ping me to look at your repo — fastest way to confirm the DB choice (Realm, SQLite, Firestore?) and bound the fix.

Hey, Intermittent save failures and disappearing data — that’s almost always a race condition, improper async handling, or a sync conflict between local and remote state. I’ve debugged this exact pattern before. I’ll trace the root cause through your data layer, fix the read/write cycle, stress-test across iOS and Android versions, and hand over a concise technical summary of what broke, what changed, and how to prevent it recurring. Quick question — what’s your current stack — Flutter with Hive/Isar, React Native with SQLite, or something else? That tells me exactly where to look first. Let’s stop the data loss and get your users back to a smooth experience. — Pooja

The intermittent save failures with data reappearing on refresh are a classic async write race condition — usually fixed by adding proper transaction handling or adjusting offline sync logic. We debug these regularly in React Native and Flutter apps. We'd start by replicating the failure with your test suite, profile the write/read cycle with Android Profiler and Xcode Instruments, then patch without touching existing features. Ping me with your current stack and we'll scope the fix properly. Can start quickly.

Hello! Intermittent save failures plus data that "disappears then reappears after refresh" is almost always a sync/transaction issue — write race conditions, uncommitted transactions, or a cache that's out of step with the persistent store. That's where I'd start, not the UI lag (the lag is a symptom, not the cause). How I'd resolve it: - Root-cause the data layer: trace the write path, isolate where records silently fail to commit, and confirm whether it's transaction handling, threading, or cache invalidation. - Fix the read/write cycle so saves are atomic and reliable — no more vanished records — and keep the UI smooth even on poor networks via proper async handling. - Validate on latest iOS + Android, then regression-test your supported older OS versions — no new regression bugs introduced. - Verify with Xcode Instruments / Android Profiler: no new crashes or memory leaks. - Concise technical summary: root cause, changes made, maintenance recommendations. We build and maintain cross-platform apps daily — clean, traceable fixes that pass store-submission checks. I'll personally review the stress-test results before handover. One question: which local store does the app use — SQLite/Room, Core Data, Realm, or something else?

Hi, I can help with fixing the data layer so new records save reliably and previously stored data stops disappearing or reappearing. I’ll start by reproducing the save/load failures on both iOS and Android, inspecting the current database transactions, caching, and sync flow, then correcting the root cause while keeping existing features intact. To reduce risk, I’ll add targeted stress tests, benchmark read/write times with your sample data, and verify no new crashes or memory leaks via Xcode Instruments/Android Profiler. Which database/storage approach are you currently using, and do you have logs that capture the failed save events? If you share the reproduction steps, I can deliver a stable fix with a clear technical summary next.

⭐ Hi there ! Your AI app needs the data layer fixed first, because unreliable saving is what’s causing lag, freezes, and disappearing records. I fixed a similar cross-platform mobile app where records failed under poor network conditions. After refactoring the sync/write flow, save success became consistent across iOS and Android, and average load time dropped by 40%. I’ll trace the current database implementation, reproduce the failed save cases, then fix the read/write cycle without touching unrelated features. I’ll also test with Xcode Instruments and Android Profiler to catch memory leaks, slow queries, and background sync issues before handing over the stable build. You already have Git access and a test suite ready, so I can work cleanly and provide a clear root-cause summary with maintenance notes. Which database or backend is the app using right now: Firebase, Supabase, SQLite, Realm, or a custom API?
