Online store FAHRENHEIT
FAHRENHEIT is a Ukrainian functional clothing brand for tourism, fishing, and the military segment: membrane jackets and pants with PrimaLoft insulation, YKK AquaGuard hardware, and Cordura and
Gelanots fabrics. Three audiences (men, women, children), dozens of models across multiple lines, a complex dual-graded size grid, and color variations. The brand needed a full-featured online store that handles the
complexity of a variant-heavy assortment with multiple sizes and colors, provides automatic two-way product and order synchronization with the ERP, and gives the buyer a smooth path from search to payment - with
comparison, favorites, pre-orders, and one-click purchasing.
Task
Develop an online store for FAHRENHEIT with a complete ecommerce cycle: a catalog with multi-level filtering, size and color variants, product card grouping by color, product comparison,
favorites, and a discounts section. Implement two-way ERP integration (product import, stock updates, order export), a pre-order system with email notifications on stock changes, one-click purchase, and in-checkout
account login. Connect Nova Poshta, LiqPay, and call tracking. Perform initial SEO optimization and page speed optimization. Deliver a bilingual interface (UA/EN).
What was done
- Developed a PHP framework backend with a product variant architecture: each model supports multiple sizes with dual grading (size and height) and color variations with individual stock levels and imagery. Product cards in the catalog are grouped by color so the buyer sees all variants of a single model side by side.
- Built a catalog with multi-level navigation: a mega menu by audience (Men, Women, Children), categories by purpose (Tourism, Fishing, Military), special sections (Bestsellers, Solar Guard), and a dedicated "Discounts" section with a red "Hot" badge in the navigation.
- Implemented full-featured catalog filtering: by category, size, color, price range, material, and other attributes with AJAX updates without page reload.
- Created a detailed product page with a gallery, size and color selectors, a size chart link, availability status, price, "Buy" and "Buy in one click" buttons, wishlist and comparison icons, quantity counter, and social sharing.
- Built a tabbed "Description & Specifications / Reviews" block on the product page: a structured technical parameter table (material, insulation, hardware, waterproofness, breathability, weight) and a reviews module with ratings.
- Implemented a product comparison system with a header counter: the buyer adds models and views a side-by-side specification table to aid decision-making.
- Created a wishlist with a header counter and quick navigation to purchase.
- Implemented in-cart size changing: the buyer can adjust the size directly in the cart without removing and re-adding the item, with automatic stock availability validation for the selected size.
- Built a pre-order mechanic: when a product is out of stock, the buyer submits their email and automatically receives a notification when stock levels change.
- Implemented in-checkout account login: the buyer can register or sign in during the checkout step without losing cart contents.
- Integrated with the ERP in both directions: product import with stock levels, prices, and specifications from the ERP to the website, and automatic export of new orders from the website back to the ERP for manager processing.
- Connected Nova Poshta API for automatic shipping cost calculation and warehouse selection with autocomplete, and LiqPay for online payment.
- Integrated call tracking to monitor calls from different advertising channels with a "Call us?" button and dynamic number substitution in the header.
- Performed initial SEO optimization: meta tags, structured data, human-readable URLs, XML sitemap, heading and image alt attribute optimization for search engine indexing of the catalog.
- Optimized page load speed: image lazy loading, CSS/JS minification, server-side caching to retain mobile traffic.
- Built a "FAHRENHEIT & Life" section with a masonry grid of lifestyle photography and a "See more" button to build an emotional brand connection.
- Delivered a bilingual interface (UA/EN) with a header toggle.
- Built responsive layouts: mobile version with vertical category stacking, burger menu, optimized product cards, and a streamlined checkout.
