Hire a WordPress Developer.
Custom. Fast. Headless-ready.
Looking for a freelance WordPress web developer? I'm Aleksandar Kuzmanovic — a full-stack developer with deep WordPress expertise. I build custom WordPress themes, WooCommerce stores, and headless WordPress solutions that are dramatically faster and more SEO-friendly than standard WordPress sites.
Whether you need to improve your WordPress website speed, build a custom WooCommerce store, or migrate to a headless WordPress architecture with Next.js — I deliver WordPress solutions that perform. My headless WordPress eCommerce book store achieves perfect Core Web Vitals scores and is optimised for organic discoverability.
WordPress still powers over 40% of all websites on the internet, but most WordPress sites underperform because they rely on bulky themes and excessive plugins. I build WordPress differently: custom themes with clean code, optimised database queries, server-side caching, and when maximum performance is required, headless architectures with Next.js frontends.

Technology Stack
Modern WordPress development explained.
WordPress powers over 40% of all websites on the internet, but most WordPress sites are slow, insecure, and poorly built. The difference between a template-based WordPress site and a professionally developed one is dramatic: 5-10x faster load times, significantly better security, and SEO performance that drives measurable organic traffic growth.
Page builders like Elementor, Divi, and WPBakery have made WordPress accessible to non-developers, but at a significant performance cost. These tools generate excessive DOM elements, load unnecessary CSS and JavaScript, and create render-blocking resources that tank Core Web Vitals. A custom WordPress theme, built by hand, eliminates this bloat entirely — loading only the code your site actually needs.
Headless WordPress represents the future of high-performance WordPress development. By using WordPress as a content management backend and building the frontend with Next.js, you get the familiar WordPress admin interface that content teams love, combined with the performance and SEO benefits of server-side rendering, automatic code splitting, and image optimisation. Aleksandar has built headless WordPress eCommerce stores that achieve perfect Lighthouse scores.
WordPress security is a critical concern that most site owners underestimate. Outdated plugins, weak passwords, and default configurations are exploited by automated bots daily. Aleksandar's WordPress development includes security hardening from day one: file permission configuration, login attempt limiting, XML-RPC disabling, security headers, and regular update management.
For WooCommerce stores, the quality of development directly impacts conversion rates and revenue. Custom product page templates with structured data earn rich snippets in search results. Optimised checkout flows with fewer steps and guest checkout options reduce abandonment. Server-side rendered pages load instantly, keeping impatient shoppers engaged. Every WooCommerce store Aleksandar builds is engineered for both speed and conversion.
Common questions.
Clear answers.
- Why hire a WordPress developer instead of using page builders?
- Page builders like Elementor add significant bloat, slowing your site and hurting SEO. Custom WordPress development means clean code, faster loads, unique design, better security, and full control.
- What is headless WordPress?
- Headless WordPress uses WordPress as a content backend while the frontend is built with Next.js. You get the familiar WordPress admin with dramatically faster loads, better SEO, and superior UX.
- How can I improve my WordPress website speed?
- Quality hosting, server-side caching, image optimisation with WebP, minimising plugins, CDN setup, database optimisation, deferring non-critical JS, and potentially going headless.
- Can you migrate my WordPress site to headless?
- Yes. I migrate existing WordPress sites to headless architectures with Next.js frontends while preserving all content, SEO equity, and the familiar WordPress editing experience.
- How much does it cost to hire a WordPress developer?
- Costs depend on project scope. A custom WordPress theme takes 2-4 weeks. A WooCommerce store takes 3-6 weeks. A headless WordPress migration takes 4-8 weeks. Contact Aleksandar for a detailed quote based on your specific requirements.
- Can you build custom WordPress plugins?
- Yes. Aleksandar develops custom WordPress plugins for specialised functionality — custom post types, admin interfaces, API integrations, and workflow automation. Clean PHP code that follows WordPress coding standards.
- Do you provide ongoing WordPress maintenance?
- Yes. Aleksandar offers WordPress maintenance including plugin updates, security patches, performance monitoring, backup management, and content updates. Keeping your WordPress site secure and fast post-launch.
