Custom software developer · Auckland, NZ
Off-the-shelf software almost fits, so your team fills the gaps with paper, spreadsheets and copy-paste. I build custom web apps for New Zealand service businesses that replace those workarounds, and I keep them running after launch.
Who this is for
Owner-run service businesses, usually 5–50 people, where the work is too specific for a generic app. If a few of these sound familiar, we should talk:
Recent work
Three different businesses. In each one, work that lived on paper and in people's heads moved into a system the whole team uses.
Case study 1 · Veterinary practice · NZ
The problem. A veterinary practice managing dozens of dairy farm clients had no central system. Five different consultation types — medicine assessments, milk quality reviews, animal health, quarterly planning — all tracked manually. Every report written by hand, every client history scattered across files.
The result. A secure multi-user platform where vets log in with their existing Microsoft 365 credentials and immediately see every client, every consultation history, and every past report. Five structured consult workflows built in. Reports export to PDF or Excel automatically.
All client data sits behind Microsoft 365 authentication — no new passwords, no separate accounts.
Currently expanding with AI-powered clinical recommendations — surfacing insights from consultation history automatically.
Case study 2 · Nonprofit organisation · Auckland, NZ
The problem. A nonprofit running multiple client-facing services was taking all bookings manually — phone calls, paper diaries, handwritten sign-up forms. Each service operated independently. Appointments missed, reminders forgotten, staff time consumed by admin that had nothing to do with serving clients.
The result. An automated booking system embedded into the organisation's website. Clients book online, receive instant confirmation, and get automated reminders — without anyone on staff doing anything. Every service feeds into one central system, giving management a live view across the whole operation.
Built on top of tools the team already used — no disruption to existing workflows.
Case study 3 · Towing & vehicle storage · NZ
The problem. A towing company's office server died — and took with it the on-premise software, dating back to the late 1990s, that ran their entire vehicle tracking operation. With replacement parts weeks away, staff were logging every impounded and accident-towed vehicle on paper and printed dockets, manually tracking cars that had been in storage for months. Storage fees, owner details and billing were all being handled by hand, with no way to add new records.
The result. A cloud-based management platform, accessible from any device, that replaced the dead on-prem system entirely. Staff log every tow with vehicle, owner and storage details; storage fees calculate automatically from intake to release date; and GST invoices generate from the same record. Configurable rate settings handle the different charges for accident versus impound tows.
Because it's online, the office is no longer tied to a single machine — the original point of failure is gone for good.
What I build
Custom business apps
Multi-user web apps built around your process: jobs, clients, bookings, stock, whatever your business runs on. Works on any device, with secure logins for your team.
Bookings & scheduling
Online booking with automatic confirmations and reminders, so nobody on staff has to chase appointments.
Reports & invoices that write themselves
PDFs, spreadsheets and GST invoices generated from the data you already have, in seconds rather than hours.
Connecting your existing tools
Your accounting, email, forms and spreadsheets pass data to each other automatically, so nobody has to re-type it.
Replacing old or failed systems
Ageing software on one office PC gets moved to the cloud. It's fast when something has already broken and planned when it hasn't.
Ongoing support
One person who knows your system inside out. I fix issues, make improvements and add features as the business grows.
How it works
Tell me what's slowing you down
Send a few lines or book a quick chat. I'll tell you honestly whether custom software is the right fix, even if the answer is "you don't need me". No cost, no obligation.
We map it out
I learn how your business actually runs, then come back with a clear plan: what we'll build, how long it takes and a fixed price, all before you commit to anything.
I build it
You see progress as it happens. Launch includes testing, training for your team and handover docs.
I stick around
Once it's live, I stay on to handle support, fixes and new features as the business grows, so you're not starting over with someone new each time.
I'm Hamish, a developer based in Auckland. You deal with me directly, with no account managers and no handoffs. I explain things in plain English and build software your team will actually want to use.
Send a few lines about the problem and I'll reply within 24 hours with honest thoughts on how I'd fix it, and whether it's even worth doing. No cost, no obligation.
