Custom web applications, built around your workflow
Off-the-shelf software makes your business bend around it. A custom web application does the opposite: client portals, booking engines, quoting tools and operations dashboards shaped to the way your team already works — then made faster.
I design, build and ship the whole thing myself: data model, backend, interface and deployment. You brief the person writing the code, and you see working software on a private staging link every single week.
What I build
Client & customer portals
Secure logins where your clients see the status, documents and history that matter to them — instead of emailing you for updates.
Booking & quoting engines
Availability, pricing rules and follow-ups handled by software, so a quote goes out in minutes rather than days.
Operations dashboards
The numbers your business runs on — jobs, margins, pipeline — live on one screen instead of scattered across six exports.
Workflow tools
The process that currently lives in one person’s head or a fragile spreadsheet, turned into software the whole team can run.
How an engagement runs
Every build starts with a free thirty-minute discovery call and a written, fixed-price proposal — what gets built, what it costs, when it ships. Full web applications typically take six to twelve weeks, with a demo of real working software every week so you steer while steering is cheap.
You own everything from day one: the repository, the infrastructure and the documentation live in your accounts. Most projects land between $6k and $60k AUD depending on scope, and you’ll know the number before any work begins.
Fair questions, straight answers
How is a custom web app different from a website?
A website tells people about your business; a web application runs part of it. Logins, data, workflows, integrations — software your team and clients use daily, not a brochure.
What stack do you build web applications with?
React and TypeScript on the front end, Node.js and PostgreSQL behind it, deployed on AWS or similar infrastructure with monitoring and backups from day one. Boring, proven technology — chosen so any competent engineer can maintain it after me.
Can you take over or rescue a half-finished build?
Usually, yes. Rescuing stalled projects and integrating with legacy systems is a specialty — I’ll audit what exists, tell you honestly what’s salvageable, and quote from there.
Tell me what’s slowing your business down.
