Custom WordPress Theme Development
Stoneberg Design specializes in custom WordPress theme development that bridges design vision and technical execution. We build enterprise-grade themes for organizations that need more than off-the-shelf solutions, companies where brand consistency, performance, and content flexibility are non-negotiable.
Our theme development process starts with a component inventory and design system audit. This foundation ensures every theme element is intentional, reusable, and accessible. We build with Gutenberg-first architecture, creating custom blocks and block patterns that give content teams powerful editing capabilities while maintaining design guardrails.
Performance is baked into every theme we build. We optimize asset loading, minimize JavaScript dependencies, implement efficient caching strategies, and rigorously test against Core Web Vitals. Our themes for enterprise clients like Tableau and Salesforce handle high traffic volumes while delivering fast, responsive experiences across devices.
Accessibility isn't an afterthought; it's integrated from the first component. We follow WCAG 2.1 AA guidelines, test with screen readers, ensure keyboard navigation works throughout, and provide semantic HTML that supports both users and SEO. Every theme ships with comprehensive documentation, including component libraries, style guides, and developer handoff materials that set your team up for long-term success.
