VBA Developer Needed to Reconcile Inventory

We are looking for an experienced VBA / Database Developer to help us resolve a technical misalignment in our inventory management system's go-live data. The system utilizes a FIFO engine where IngredientBatches controls batch availability, and a movement-led IngredientStock ledger calculates live stock based on receipt/consumption transactions. Currently, a gap in our opening balance setup has caused our live stock dashboard to display negative figures. The strategy and a core fix module (mod_OpeningStockReceipts.bas) have already been outlined. We need an expert to run diagnostics, align the columns, execute the fix safely, and ensure full system reconciliation without disrupting existing consumption history. Scope of Work Module Integration: Import and test a provided VBA module (mod_OpeningStockReceipts.bas) designed to generate missing opening receipt entries in the movement ledger from existing batch data. Column & Data Alignment: Run data validation checks (via a provided macro) to identify and correct misaligned data columns (specifically Status and RemainingQty in the IngredientBatches table). Data Reconciliation: Ensure that: IngredientStock reconciles perfectly with positive opening balances. FIFO batches remain completely unchanged. Existing ConsumptionLedger records stay intact. No duplicate stock movements are created. System Validation: Rebuild and validate the live stock dashboard formulas to ensure future "End of Day" automated runs function reliably. Thank you

WEB app to Native App conversion (Not wrapped)

I have a web app (Zekko Golf, a golf scoring/game app) built in Base44. I need it published as a native app on the Apple App Store and Google Play, with RevenueCat handling in-app subscriptions and one-time purchases. All RevenueCat and store-side configuration is already complete — this is a native build, SDK integration, testing, and submission job, not a build-from-scratch. You must have a Mac with Xcode (for iOS) and Android Studio. Important context (please read before quoting) The app currently lives in Base44, which does not allow native plugins in its managed build. The app needs to be exported (Base44 supports GitHub export) and built as a native Capacitor project. A previous wrapper attempt was rejected by Apple under Guideline 4.2 (minimum functionality). You must be able to ensure the app has enough native substance to pass App Store review. Please explain your approach to this. Phase 1 — Paid assessment first (small, ~1–2 hours) Before committing to the full job, I'd like you to: Export the app from Base44 (GitHub) and confirm it builds as a workable Capacitor project. Confirm it can be made to pass Apple Guideline 4.2. Give me a fixed quote for the remaining work (Phase 2).
