Frequently Asked Questions
Why does website loading speed matter for Waterford businesses?
Fast-loading websites rank significantly higher on Google, keep potential customers engaged, and reduce bounce rates. A high-performance website ensures visitors stay on your site and convert into paying customers.
What is John Riordan's approach to high-performance web development?
John Riordan builds websites engineered for rapid load speeds and clear customer conversions. This is achieved through lean code, modern image compression (like AVIF), lightweight scripts, and clean mobile architectures. The aim is to deliver a smooth user experience while minimising data consumption and securing top Lighthouse scores.
How does private on-premise AI work without sending data to the cloud?
Open-weight AI models are installed directly on your own computer or office server rather than a third-party cloud service. Everything runs locally and offline, so confidential client details, documents, and correspondence never leave your premises, with no ongoing AI subscription fees.
What is the difference between an installable web app and a native App Store app?
A Progressive Web App (PWA) installs straight to iOS and Android home screens from the browser and works offline, without needing separate codebases or App Store approval delays. Updates go live immediately at a fraction of traditional native development costs.
How much does a website or app cost, and how does the process work?
Every project is scoped around the pages, integrations, and features you need, starting with an initial chat or in-person consultation across Waterford and the South East. You receive a clear fixed-price quote before any work begins, with no surprise fees or platform lock-in.
