Custom WordPress Themes That Perform
Hand-coded themes without bloated page builders. Fast, secure, and built to rank.
Your Premium Theme Is Costing You Conversions
Most "premium" WordPress themes from marketplaces ship with dozens of scripts, font loaders, and CSS frameworks your site never uses. The average premium theme makes 47 HTTP requests on initial load and ships over 800KB of unused CSS. A custom-built Aleksandar Rasevic theme typically loads in under 12 requests with a 90+ PageSpeed Insights score on mobile. That difference directly impacts bounce rate, search ranking, and revenue.
Performance First
No builder bloat, no unused scripts. Themes score 90+ on PageSpeed Insights and load in under 1.5 seconds on 4G.
Built Secure
No nulled code, no hidden backlinks, no dependency on abandoned third-party libraries. Full ownership of your codebase.
SEO-Native
Semantic HTML5 markup, structured data, and clean permalink structures that search engines understand without plugins.
A theme engineered for results
Custom Gutenberg Block Development
We build custom blocks using the official WordPress Block API with block.json metadata files, register them via PHP with register_block_type(), and compile JavaScript assets through Webpack with @wordpress/scripts. Your content editors get intuitive, visually consistent blocks that match your brand without relying on shortcodes or third-party builder plugins. Each block includes inline documentation and follows WordPress coding standards for long-term maintainability.
Performance-First Architecture
Every theme is built with zero jQuery dependency, deferred JavaScript loading, and critical CSS inlined into the document <head>. We use wp_enqueue_script() with defer and async strategies, implement resource hints via wp_resource_hints() for preconnecting to CDN origins, and load Google Fonts through font-display: swap. The result: a typical Aleksandar Rasevic theme scores 95+ on PageSpeed Insights mobile and achieves sub-1.2s Largest Contentful Paint on standard hosting.
Booking & Reservation Integration
We build native booking and reservation flows directly into the theme β conversational or form-based intake, real-time availability checks, and confirmation emails/SMS β instead of bolting on a generic plugin. Session resume means a visitor who leaves mid-booking picks up where they left off. Every flow is wired to conversion tracking (Google Ads, GA4) so you know exactly what a completed booking is worth.
theme.json Design System
Every theme ships with a comprehensive theme.json file that defines the entire design system: color palettes, typography scales, spacing presets, border radius values, and custom CSS properties. This locks the editor experience to your brand guidelines and prevents content editors from applying off-brand colors or fonts. We define custom settings.color.palette arrays, settings.typography.fontSizes, and settings.spacing.spacingScale so your site stays visually consistent as content grows.
Accessibility (WCAG 2.1 AA)
All themes are built to meet WCAG 2.1 Level AA standards. We use semantic HTML5 elements (<nav>, <main>, <article>, <aside>), implement skip-to-content links, ensure 4.5:1 contrast ratios on all text, and build keyboard-navigable menus with aria-expanded states. Forms use proper <label> associations and error announcements via aria-live regions. We test every theme with axe-core, WAVE, and NVDA screen reader before delivery.
SEO-Ready Markup
Themes ship with structured data implemented as JSON-LD via wp_head hooks: Organization schema, LocalBusiness markup, Article schema for posts, Service schema for bookings and appointments, and BreadcrumbList structured data. We implement Open Graph tags and Twitter Cards via wpseo_add_opengraph_additional_images integration, use canonical URLs on every template, and generate XML sitemap-friendly permalink structures. The breadcrumb navigation outputs itemListElement microdata automatically on all archive and single templates.
Multilingual Ready
Themes are built with internationalization in mind: all strings wrapped in __() and _e() functions with proper text domain registration, RTL stylesheet support via rtl.css, and full compatibility with Polylang and WPML. Custom blocks expose translatable attributes through i18n domain declarations in block.json. We also implement hreflang link tags for multilingual SEO and test all layouts in both LTR and RTL orientations before launch.
Post-Launch Support
Every theme delivery includes 30 days of bug-fix support, a detailed handover document covering file structure, block usage guides, and video walkthroughs for content editors. We provide a CHANGELOG.md for version tracking, semantic versioning for theme releases, and a staging-to-production deployment workflow using WP-CLI. Ongoing maintenance plans include monthly security audits, WordPress core compatibility checks, and performance monitoring via Query Monitor and New Relic integration.
How we work
Discovery & Requirements
We audit your existing site with GTmetrix, Query Monitor, and Screaming Frog to document current performance bottlenecks and SEO issues. We interview your content editors to understand their publishing workflow, define user personas, and map the required template hierarchy: which post types need custom single templates, which archives need faceted filtering, and what role-based access is needed for the admin dashboard. Deliverable: a technical specification document with sitemap, wireframe annotations, and template list.
Wireframing & Prototyping
We build interactive prototypes in Figma for every unique template: homepage, single post, archive pages, search results, 404, and any booking/reservation flow templates. Each prototype includes desktop, tablet, and mobile breakpoints at 1440px, 768px, and 375px. We define the theme.json color and spacing tokens at this stage and present a living style guide that becomes the contract for the final build.
Theme Development
We scaffold the theme using a custom boilerplate based on _s (Underscores) with modern tooling: Webpack 5 for asset compilation, Sass for stylesheets, and Browsersync for live reloading. PHP templates are organized under template-parts/ with separation of concerns: loops in template-parts/loops/, partials in template-parts/components/, and custom queries as reusable functions in inc/template-functions.php. We version-control on Git with feature branch workflow and deploy to staging via GitHub Actions.
Content Integration
We import your existing content using WP-CLI migration scripts, map old shortcodes to new custom blocks with programmatic transformations, and configure all navigation menus, widget areas (or block template parts in FSE themes), and customizer settings. Every page is populated with real content, not lorem ipsum, so we catch edge cases early: long headlines, missing featured images, nested categories, and special characters in slugs.
Testing & QA
We run the theme through a 40-point QA checklist: cross-browser testing on Chrome, Firefox, Safari, and Edge; mobile testing on iOS Safari and Android Chrome; accessibility audit with axe-core; performance testing on Lighthouse with 4G throttling; and WordPress coding standards validation via PHP_CodeSniffer with WordPress-Extra ruleset. All custom blocks are tested with the WordPress plugin directory's block validator. Booking and reservation flows undergo end-to-end testing across the full flow, not just the happy path.
Launch & Monitoring
Launch day involves a scripted deployment: database backup, DNS cutover with minimal TTL, search-replace for URLs via WP-CLI, and 301 redirect mapping from old URLs. We monitor the first 72 hours with Query Monitor for slow queries, configure caching via WP Rocket or server-level FastCGI cache, and submit the new sitemap to Google Search Console. A post-launch report documents before/after PageSpeed scores, crawl error resolution, and a 30-day support calendar.
Technologies we use
"Our dental practice website went from page 4 to page 1 on Google within three months of Aleksandar Rasevic rebuilding it. The structured data implementation alone was worth the investment."
Frequently Asked Questions
How long does a custom WordPress theme take to build?
A typical business website with 6-8 unique templates takes 4-6 weeks from discovery to launch. Projects with complex booking/reservation logic or multi-step configurators generally run 8-10 weeks. Large-scale publisher sites with faceted search, membership areas, and custom editorial workflows can extend to 12-14 weeks. We provide a detailed timeline with milestone-based deliverables after the discovery phase so you know exactly what ships when.
Will my theme work with page builders?
We intentionally do not support Elementor, Divi, or WPBakery in our custom themes. These builders inject proprietary shortcodes and lock you into their ecosystem. Instead, we build native Gutenberg blocks that give your editors the same visual flexibility without the performance penalty or vendor lock-in. If you are migrating from a page builder, we provide a shortcode-to-block migration script as part of the project. The result is a site that renders in pure HTML with zero builder overhead.
Do you support booking and reservation systems?
Yes β this is a core specialty, not an add-on. We have built booking and reservation flows for restaurants, clinics, and hospitality clients, with real-time availability, session resume, and confirmation via email, SMS, WhatsApp, or Viber. We also build the AI-assisted conversational booking flows described on our AI Chatbots & Booking Automation page, if a form alone isn't enough.
Can you migrate my existing site to the new theme?
Absolutely. Site migration is included in every theme project. We use WP-CLI for database exports and imports, run search-replace for URL updates, write custom migration scripts for transforming old shortcodes into Gutenberg blocks, and map all URLs with 301 redirects to preserve SEO equity. We schedule migrations during low-traffic windows and perform a full content freeze to prevent data loss. Post-migration, we submit the new sitemap to Google Search Console and monitor for crawl errors.
What happens after launch?
Every launch includes 30 days of post-launch support covering bug fixes, browser compatibility issues, and minor adjustments. After that, you can opt into a monthly maintenance plan which includes: WordPress core and plugin updates, security scanning with Wordfence, uptime monitoring, monthly performance reports, and up to 4 hours of content or styling changes. All maintenance clients get priority support with guaranteed 24-hour response time.
