Current work

Technology work with a practical edge

John Finnerty is based in Christchurch and works across software development, websites, business email, DNS, networking, technical documentation, and support workflows for small teams. The focus is simple: useful systems that are understandable, maintainable, and easy for real people to operate.

Project notes and static-site work

Web applications, public source archive projects, portfolio pages, structured data, metadata, and technical SEO foundations.

Business technology

SME systems

Automation & evidence

Cleaner workflows

Repeatable checks, data quality, documentation, browser diagnostics, support trails, and practical automation for common tasks.

Working style

Clear, evidence-led, and maintainable

The common thread is practical problem solving: make the system understandable, document what changed, validate the result, and leave the next person with a cleaner path forward.

Plain-English support

Useful technical help should make decisions easier, not hide behind jargon.

Search-ready structure

Pages need accurate metadata, schema, canonical URLs, and internal links to support discovery.

Documentation that survives handover

Good notes, repeatable checks, and rollback paths reduce stress when something changes later.

Practical support paths

These pages translate the professional profile into practical support areas for websites, DNS, email, networking, fibre, VoIP, and SME technology setup.
