Meet Sebastian Pettifer: Building Sites That Perform, Not Just Sites That Look Good

I am a web designer and developer specializing in dynamic, high-performing websites built on WordPress. With an eye for design and a deep understanding of user experience, I build sites that are visually compelling and engineered for functionality, speed and conversions. My approach keeps every build aligned with the client’s brand and business goals, and I stay close to industry changes so the work stays current rather than dated the year after launch.

A site that looks good but loads slowly does not convert. A fast site that confuses people does not convert either. I work across both sides of that problem, so the design decisions and the technical decisions get made together instead of being handed between people who never speak.

Day to day that covers layout and visual design, WordPress theme and template development, page speed and Core Web Vitals, mobile behaviour, form and funnel construction, accessibility, and the security and maintenance work that keeps a site healthy long after launch.

What I Focus On

• WordPress design and development — custom builds and rebuilds, not templates dropped in unchanged
• Performance — page speed, Core Web Vitals, and the technical debt that quietly slows a site down over years
• User experience — navigation and page hierarchy that match how visitors actually move through a site
• Conversion — forms, calls to action and funnel paths built to be finished, not abandoned
• Security and maintenance — hardening, firewall configuration, updates and monitoring across every site we manage
• Brand consistency — keeping the build faithful to the identity the client already owns

Development does not sit on its own here. A site is usually the destination for search traffic, paid campaigns and content, so it has to be built to receive them: clean structure for search engine optimization, landing pages that hold up under paid traffic, and a foundation the content strategy can grow into.
