At Stellar, we don’t just optimize — we help you grow. Our solution-first approach focuses on real results, improving sales, user experience, and revenue.
From eCommerce to fintech, our clients span 20 countries and every project is different.
How we moved retail and trade to Shopify Plus on native B2B, no custom backend - B2C on schedule, trade portal a month later.
How we rebuilt the storefront, split the EU and US into separate stores, and set up Shopify Markets for Europe - without pausing orders.
How we rebuilt the store on Online Store 2.0, simplified checkout, and automated inventory and marketing with NestJS, Klaviyo and Zapier.
How we moved the widget to App Blocks and pre-built insurance variants - so merchants self-install and protection reaches the cart instantly.
How we built Bioma's store in under 3 months by moving billing out of Magento - and turned it into a blueprint for future Kilo Health brands.
How we moved Côte&Ciel's three Shopify storefronts out of the PageSpeed red zone without pausing sales.
How we built a breed-based quiz, calorie calculator and multi-discount cart on Web Components and Alpine.js - for a store where 87% of traffic is mobile.
How we rebuilt search, performance and analytics on a live Magento 2 store, cutting order processing time by 22% and lifting ROAS by 18%.
A new theme, rebuilt subscriptions and ClassWallet payments - with every customer, order and subscription carried over.
How we moved a hardcoded Dawn theme to Horizon and metaobjects - so the marketing team updates menus, banners and promotions on its own.
How we rebuilt the storefront on Hyvä, upgraded Magento to 2.4.7-p1, and rebuilt the prescription consultation engine - with zero downtime.
How we moved a legacy monolith to async Laravel queues so sellers manage Amazon orders right in Shopify.
How our six-person team builds market-specific checkout logic, maintains REST API integrations, and ships fixes without putting live sales at risk.
We built a free Shopify app that checks storefront pages, scores their SEO health, and turns findings into practical next steps.
