Sub-Second Commerce.
Zero Limitations.
We decouple your frontend from legacy constraints. Sterk builds high-performance headless storefronts using Next.js 15 and Payload CMS. Keep your backend, upgrade your growth.
Why "Standard" E-Commerce is failing you.
Traditional monolithic platforms (Shopify/Magento) are built for the back-office, not for the modern web.
Latency Kills Conversion
Every 100ms of latency costs you 7% in conversions. Slow sites bleed revenue before the customer even sees the product.
Lighthouse Score Matters
If your Lighthouse score isn't 100, you are visible less often and paying more for ads. Speed is a ranking factor.
Legacy Bloat
Direct database calls on every page load and unoptimized assets create a bottleneck that scaling servers can't fix.
Core Services
Everything you need to modernize your e-commerce stack without starting from scratch.
Headless Migration
We migrate your frontend to a modern React-based stack without the risk of a full data migration. Keep your existing backend logic intact.
Unified API Layer
We build the "bridge" between your existing ERP/CMS and a lightning-fast frontend. Data flows seamlessly without exposing your legacy backend to direct traffic.
PWA Development
We turn your store into an installable app that works offline and sends push notifications. Engage customers like a native app without the app store friction.
