Develop a dietary supplement online store

Need to develop an online store for dietary supplements for sales across Europe, based on the example of healf.com (reference: healf.com/collections/eat). Custom development only — no ready-made platforms (Shopify and similar) to be used. Requirements: Catalog with sections for 4 health areas (Nutrition / Movement / Mental Health / Sleep), filters by goals (immunity, digestive health, longevity, women's/men's health), product type, and brands. Product cards: photo, price, rating and reviews, quick add to cart, favorites. AI mechanism for importing and populating the product database: automatic import from supplier price lists/feeds (CSV, XML, API), AI-generated descriptions, characteristics, and SEO texts in multiple languages, automatic product categorization. Integration with European delivery services (DHL, DPD, GLS, InPost, etc.): cost calculation, shipment creation, tracking. Cart and online payment (cards, Apple/Google Pay, preferably Klarna/PayPal), promotions ('buy 3, get 1 free'), free shipping over a certain amount. Multilingual (minimum EN + DE, expandable) and multi-currency (EUR, GBP). Admin panel: products, orders, promotions, AI import management. Wellbeing blog, brand pages, email subscription. Minimalistic premium design like the reference, mobile responsive, SEO basics, GDPR (cookie banner, policies). We expect a proposal on architecture, tech stack, timeline, and cost, preferably with a prototype.

Instead of describing the approach, here's a live store built for your task (reference — curated wellbeing marketplaces like healf.com). Everything below is already working at the link:

Catalog and Navigation

4 health categories (Nutrition / Movement / Mind / Sleep) + filters by goals: immunity, gut health, sleep, longevity, energy, etc.
Product card: photo, brand, rating and reviews, price, category and goal tags, "Add to Cart" button.
"Frequently Bought Together" block on each product card — recommendations are selected based on matching goals and categories (e.g., creatine with protein and magnesium, not random items).

Cart and Promotions

Cart drawer with a "buy 3, get 1 free" promotion (the cheapest of every four is free) and a progress bar towards free shipping from €50.
Cart is saved when navigating between pages.

Multilingual Support

4 languages are already in the prototype: Ukrainian, Russian, English, German — a dropdown switcher, everything is translated, including menu items. The architecture is expandable to any EU languages.

Mobile Version — adaptive: compact header, navigation by categories in a separate row, product grid for narrow screens.

Admin Panel (link in the footer) — products with stock levels, orders with statuses, customers with CRM segments (new / repeat / VIP).

In the full version, I will add: AI import of product feeds with auto-generation of descriptions and SEO texts in EU languages (with health claims verification according to EU Regulation 1924/2006), Stripe/PayPal/Klarna payments, DHL/DPD/GLS/InPost delivery, PostgreSQL + search with faceted filters.

The prototype was built in hours, not weeks — I will iterate just as quickly going forward: tell me what to change, and you'll see it at the same link on the same day.

Обновление: прототип переехал на постоянный адрес — **https://www.gptaria.com/p/vitalis** (старая ссылка тоже работает и ведёт сюда). Добавились карточки товаров с блоком «часто заказывают вместе» — кликните любой товар в каталоге.
