I build and improve digital systems for businesses — from software, integrations and automation through to cyber security, web performance, SEO and AEO.

My work tends to sit where development, infrastructure, commercial performance and technical strategy overlap. I work directly with businesses through erryn.io, including fractional CTO support for organisations that need senior technical capability without building a full internal function.

• Software & integrations — bespoke tools, APIs, CRM/telephony integrations and workflow automation
• Cyber security — Cyber Essentials, security hardening, infrastructure review and incident response
• Web performance — WordPress and WooCommerce optimisation, Core Web Vitals and page-speed engineering
• Search & discoverability — technical SEO, AEO, structured data, indexing and search architecture
• Technical strategy — platforms, infrastructure, migrations, architecture and Fractional CTO support
