Build
New sites, small tools, dashboards, and online systems built from nothing.
- Websites
- Internal tools
- Dashboards
INDEPENDENT DIGITAL PRACTICE
Websites, software, and digital services for businesses.
I help businesses build, fix, and improve the digital things they rely on — the site, the workflow, or the small tool that's currently held together with a spreadsheet and hope.
Direct — you work with the person doing the build, not an account manager.
Clear scope agreed before anything gets built.
WHAT I HELP WITH
Most digital problems fall into one of three buckets.
If your problem doesn't fit neatly into any of them, tell me anyway — that's usually still a yes.
Improve
Existing websites, workflows, and data made faster, clearer, and easier to use.
- Redesigns
- Workflows
- Data cleanup
Solve
Technical problems, integrations, conversions, and the odd job nobody else wants to touch.
- Integrations
- Automation
- Migrations
SELECTED WORK
A few things built to show how I work.
Independent sample builds, not client projects — open any of them and use it.
WEBSITE
Website rescue
The problem: a small-business site nobody could read on a phone, with a contact form that led nowhere. What was built: a rebuild around a clear service list, a readable layout at any width, and one obvious way to get in touch.
Demonstrates design, responsive layout, and a conversion path that actually works.

AUTOMATION
Lead intake
The problem: every enquiry landed in one inbox and had to be sorted by hand. What was built: a routing workflow that reads each enquiry and sorts it into a visit, a schedule, or a no — with test fixtures proving the routing logic.
Demonstrates business logic, workflow design, and repeatable automation.

INTERNAL TOOL
Operations board
The problem: jobs, technician load, and unpaid invoices lived in three different spreadsheets. What was built: one screen showing open jobs, who's busy, and which invoices are aging, with working filters.
Demonstrates software UI, data organization, and business-logic thinking.

HOW I WORK
Four steps, no surprises in between.
- Understand The problem, and what done looks like.
- Build The site, the workflow, or the tool.
- Test The path that has to work.
- Deliver The finished work, with notes when they're useful.
WORKING PRINCIPLES
What working together actually looks like.
Clear scope
You know what's being built, and what isn't, before work starts.
Direct communication
You work with the person doing the implementation. No account layer in between.
Practical execution
The goal is a working solution, not unnecessary complexity.
Visible work
Representative builds are on this site to open and inspect, not just describe.
