Technology Stack
Building eCommerce that converts.
The difference between an eCommerce store that generates revenue and one that collects digital dust comes down to three factors: speed, SEO, and user experience. Aleksandar Kuzmanovic engineers all three into every eCommerce project, producing measurable results like 200% conversion lifts and 900% traffic growth.
Speed is the single most impactful factor in eCommerce conversion. Research consistently shows that every additional second of load time reduces conversion rates by 7-10%. Aleksandar has built Serbia's fastest automotive eCommerce platform with sub-1-second load times using Next.js server-side rendering, image optimisation, and edge caching. Fast stores sell more — it's that simple.
eCommerce SEO requires specialised knowledge beyond general SEO. Product schema markup earns rich snippets with prices, ratings, and availability in search results. Category page architecture determines whether you rank for high-volume commercial terms. Internal linking between categories, products, and content pages distributes authority and improves crawl efficiency. Aleksandar implements all of this at the code level.
Headless commerce has emerged as the dominant architecture for performance-critical eCommerce. By decoupling the frontend from the commerce backend, you get the speed of Next.js with the inventory management of WooCommerce, Shopify, or a custom API. Aleksandar has built headless WordPress eCommerce stores that combine the content management ease of WordPress with the performance of a modern React frontend.
The admin experience matters as much as the customer experience. Aleksandar builds custom admin dashboards that give store owners complete control: product management, order processing, customer data, inventory tracking, discount codes, and sales analytics. No monthly platform fees, no feature limitations, and no vendor lock-in.
