A language learning app developing

We need to develop an app for Russian-speaking people to learn English words. The idea is that each student will have a personal account, which they can use to view flashcards with words. The flashcards are double-sided, with translations and audio (they work like Anki). We also need a way to test the student's knowledge of the words they've learned (multiple choice). The app shouldn't automatically translate words; I'll be adding all the words manually. The main thing is to have a distinctive design, which I'll describe roughly.

Shopify Developer & Design - product template + metafield system

We're an established UK online building-products retailer (large catalogue) levelling up our Shopify store, supplier by supplier. We're looking for a design-capable Shopify developer — someone who builds clean, well-structured Shopify and has a genuine eye for design. This first project builds the reusable foundation our whole catalogue will run on, then completes one product range (external cladding, ~11 products) as the gold-standard template. What the project involves: Set up a metafield + metaobject structure for product specs (material, colour, RAL, coverage, fire rating, dimensions, lead time, warranty) and per-brand info Build one flexible, well-designed product + collection template that auto-renders spec tables, a brand block, swatches and a coverage calculator from those metafields Configure storefront filters (Search & Discovery) from the metafields Add Product/Review schema and handle canonical/robots on filter URLs (no URL/handle changes — existing handles stay) Complete one cladding range end-to-end as the exemplar, including collection pages with auto-fill rules You must be able to show: Shopify metafield + metaobject experience Storefront filtering (Search & Discovery or similar) Liquid theme section development A portfolio of stores that genuinely look good, not just function Important: there's a design sign-off stage — you'll build the example product page in the template and we approve the look before go-live, as it becomes the template every other product inherits. Strong work leads to ongoing rollout across the wider catalogue at an agreed per-range rate. To apply, please include: Two or three Shopify stores you've built (ideally large catalogues with filtering) One line on how you'd structure metafields for a product that comes in multiple colours and sizes Your availability and rough timeline for a project of this size

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
