Case studies
Work that speaks for itself.
Real stores we've built and shipped, alongside deep technical rebuilds — migrations, integrations, and the numbers behind them.
eCommerce platform development
Full platform development for a Swiss flash-deals and experience marketplace
Realdeals.ch runs flash-deal campaigns across French-speaking Switzerland — experience vouchers and discounted products sold side by side, each with its own pricing and rules. We built and still maintain the platform behind it.
- Catalog architecture split into Experience Deals and Flash Deals, each with its own redemption and fulfillment logic
- Regional targeting and content rules for five Swiss cantons — Vaud, Fribourg, Valais, Genève, Neuchâtel-Jura
- Time-limited pricing engine, gift certificates, and a user-to-user resale marketplace built on top of the core platform
eCommerce store development
Catalog and store development for a Dutch professional tools retailer
Superhandig.nl sells tools, workwear and chemicals to tradespeople, carrying brands like FORMAT, Wera and Knipex, each with its own attributes. We built the catalog and commerce layer: attribute filtering, live stock, and B2B support alongside retail.
- Multi-brand catalog with attribute-based filtering (tool type, size, material) across dozens of product lines
- A free-quote request flow for bulk B2B orders — build a cart, get a priced PDF offer, convert it straight into an order — running alongside the standard one-click retail checkout
- Live stock feed synced from the wholesale distributor's warehouse system, so the catalog only ever shows what can actually ship today
Retail & E-commerce
NovaMart survived Black Friday — and turned 14 hours of downtime into €420K in new revenue
NovaMart's Magento 1 store collapsed every Black Friday — 14 hours down, €114K lost in 2023. We rebuilt it on Magento 2 with a headless storefront and auto-scaling that pre-warms before every campaign.
- 340% more peak traffic handled without the site going down
- Page loads dropped from 2.8s to 1.5s
- €420K in additional revenue in year one
“Our first Black Friday on the new platform was the calmest day of the year. Zero incidents. The team actually enjoyed it — which hadn't happened in four years.”
Markus Riedel — CTO, NovaMart GmbH · Frankfurt
Catalog & localization
A supplement catalog of more than 1,500 products, rebuilt for multilingual browsing, certification content, and repeat orders
Sunday Natural sells supplements where almost every product carries its own dosage, origin and certification. We built the commerce layer around that structure, plus multilingual templates and subscription paths for repeat buyers.
- Catalog and filtering structure built around supplement-specific attributes — dosage, format, certification, ingredient origin — across a product range in the thousands
- Multilingual product templates with consistent presentation of specs, certificates, and compliance content across language versions
- Subscription and reorder logic for repeat purchase of core supplement and nutrition lines
Personalisation & gifting
Name personalisation built into the product page, cart, and production handoff for a baby and kids gifting retailer
My 1st Years sells personalised baby and kids gifts where free embroidery is the reason people buy. We built the personalisation flow — input, preview, and handoff into production — so every order prints right the first time.
- Personalisation step on the product page — name entry, placement choice, and a live preview carried accurately through to checkout
- Cart and order logic that keeps personalisation data attached to the correct line item through to the production and embroidery handoff
- Seasonal collection builds, including Christmas, with their own personalisation variants and gift-oriented merchandising
Integrations
How a 150K-product store stopped losing orders — by fixing how its systems talk to each other
A 150,000-product retailer kept losing orders because its store, PIM and CRM talked over synchronous calls that collapsed under load. We replaced them with message queues and a dead-letter safety net.
- Sync reliability improved to 99.4%, up from an estimated 85% under the old synchronous setup
- Failed syncs dropped to under a dozen a day, down from dozens during peak traffic
- Manual data fixes cut by roughly 90% — down to a handful a week instead of every morning
“We used to start every Monday untangling weekend sync failures. Now 200,000 messages a day flow through the queues without a hiccup. The operations team finally trusts the data — and we haven't lost a single order in three months.”
Daniel Kravchuk — Head of eCommerce Operations
E-commerce development & support
One storefront serving retail shoppers and professional clients
Yon-Ka Paris sells facial and body care through its Ukrainian distributor to two very different audiences — retail shoppers and professional salons — from the same catalog. We built the storefront around that split.
- Full design and development of the online storefront for Yon-Ka's Ukrainian distributor
- Separate catalog and access logic for retail customers and B2B professionals — salons and cosmetologists
- Threshold-based gift-with-purchase logic — orders over a set amount automatically add the current promotional gift to the cart, no manual rule changes needed each time the campaign rotates
Architecture
A B2B wholesale platform escaped its 8-year-old monolith — and cut deploy time from 4 hours to 8 minutes
An 8-year-old Symfony monolith meant 4-hour deploys, and one pricing bug could take down the whole platform. We split it into services behind an API gateway and moved it onto Kubernetes.
- Deploy time cut by 97% — from 4 hours to 8 minutes
- Incidents dropped to 2 a month
- GMV grew 35% in year one
“We went from being afraid to deploy on Fridays to shipping multiple times a day. The platform finally feels like it belongs to us again, not the other way around.”
Thomas Bergmann — CTO, WholesaleHub GmbH · Berlin
Payments engineering
Noda shipped instant bank-transfer checkout across four store platforms from one shared core
Noda is a European Open Banking provider — customers pay straight from their bank account, no card required. We built one shared payment core, then wrapped it in four plugins: WooCommerce, Magento, OpenCart and PrestaShop.
- One shared payment core behind four platform plugins — WooCommerce, Magento, OpenCart, PrestaShop
- Median payment confirmation time under four seconds after the webhook rewrite
- Each plugin versions and ships independently — WooCommerce v1.7, Magento v1.2, OpenCart v1.3/v1.2, PrestaShop v1.5/v1.0 — against that platform's own PHP and core-version requirements
Order management
How a retailer on 5 sales channels stopped overselling — and grew revenue 22% in 6 months
Selling across Shopify, Amazon, eBay and four stores, Thread & Co had no single source of truth for stock — just spreadsheets and 30+ oversells a week. We built a hub that syncs inventory everywhere within two seconds.
- Oversells dropped to zero
- Fulfillment time cut by 60%
- Revenue grew 22% in six months
“We used to dread every marketplace notification — half of them were oversell complaints. Now we run five channels from one screen, and haven't had a single oversell in two months.”
James Whitfield — Operations Director, Thread & Co · London
AI chatbot & storefront build
An AI consultant that finds the right book — on a storefront we built from scratch
Knygarium is a Ukrainian bookstore with a catalog deep enough that shoppers who didn't know the exact title often gave up browsing. We built the store itself, then added an AI consultant that turns a mood or genre into real matches from stock.
- Full storefront build — catalog, checkout and a dozen-plus genre categories
- AI consultant live on every page, wired into semantic search across the full catalog
- Recommendation conversations convert to a purchase about 70% more often than plain browsing
Platform migration
A 25-year Memphis packaging equipment supplier moved off Magento without losing a single ranking page
Our client is a 25-year packaging equipment supplier based in Memphis whose Magento 2 store had grown slow and expensive to maintain. Over 14 weeks we audited every integration, rebuilt their pricing-tier logic for Shopify, and migrated the catalog, order history and customer accounts — then cut over in a four-hour overnight window.
- 6,200 legacy URLs redirected with 301s, no ranking pages lost
- Organic traffic within 2% of pre-migration levels 90 days after launch
- A 14-week migration — building the Shopify theme and pricing-tier logic alongside the still-live Magento store — ending in a four-hour overnight cutover with zero missed orders
SEO & Google Ads, outdoor retail
A rebuilt SEO foundation and Ads account turned a quiet launch into a steady traffic channel
Trailcrest Supply had a solid catalog, almost no organic visibility, and Ads spend with no real conversion tracking. We fixed the technical SEO groundwork, rebuilt category pages around real search intent, and rebuilt the Ads account from scratch.
- Organic sessions grew from under 200 a month to more than 9,000 within six months
- Cost per acquisition on Google Ads dropped by 47%
- Return on ad spend went from under 1.5x to 4.8x
